how to install Mazdaspeed 3 high pressure fuel pump internals

New features

Bought my speed 3 used with a couple mods on it from a pay here pay here stealership, was very optimistic to find out if it had an upgraded HPFP among those mods, but because of the work required to take of the HPFP and verify upgraded vs. not. So I ordered the Corksport HPFP just incase it was not upgraded and can upgrade right there in then. So it turns out it had the Autotech HPFP already installed which was cool, but it still crazy how i swapped the HPFP with the Corksport one and it really made a difference, yea the car pulled before, but after swapping it its huge difference. Pushing from 1975 - 2000 PSI to 2000-2100 Psi it really pulls. Instructions were very detailed and good to the T, had zero issues upon install. Thank you Corksport for another great product and giving me a set of Autotech HPFP to sell.
Another example of Corksport's engineering prowess.

I had a reputable shop install the Corksport HPFP internals a couple months ago and have been impressed with the difference. Transitional throttle behavior is much smoother now. The new internals eliminated a "jerky" sensation which occasionally occurred when rolling on the throttle from coasting or part throttle. This had been most evident in freeway driving.

Monitoring the car with an Accessport, I recorded a peak pressure of 1750psi during acceleration runs with the factory internals. With Corksport internals, peak pressure rose to 2075psi.

In normal driving (everyday commuting vs attack-mode canyon carving) I have found that the factory tune aggressively leans out the fuel mixture, right to the edge of knock/ping. The internals did not change this behavior, and now that the LTFT has caught up after the install, I still occasionally hear knock/ping when rolling on the throttle. But despite the sound, the car's behavior is sharper and smoother.

My car's motor is basically stock (K&N panel filter, CBE).

I am the original owner and find it hard to fathom (a) that Mazda sold this car with a substandard pump, and (b) that I waited so long to trust the aftermarket advice and replace it. I highly recommend the upgrade, even for a factory tune.
Noticed better fuel pressure immediately after installing these. I couldn't do the install myself but these are well worth it for what should be a first mod on the Mazdaspeed platform. Good job Corksport!
A must have for any speed????. Definitely quality parts I’m hook on CS products I’m a CS fan 4life
My dad and I installed two of these back to back, one in a 07 MS3 and one in a '13 MS3 (funny, its the beginning and the end), the first one took an hour out of caution, the second one was half the time and both cars run great. But really, the best part isn't the fact that the part is extremely well made and feels bulletproof, it's the box it comes in. That is one hell of a box. Seriously kudos to whoever's idea that box was. I don't know what I'll do with it but I'm glad I have it.
One of the few first upgrades I did. I wanted this to be one of the first mods as I didn't want to worry about future upgrades and the benefits over the stock HPFP had me sold. The only downside is it is much easier to justify buying more parts since this essential install was done about 8 months ago. Can't complain, I love my Mazda!
Just installed my hpfp and I didn’t think I would feel as much as a difference as I did. I am so glad i listened to all the speed3 forums. Getting 1800+ psi
Don't know what to say, work flawlessly. Easy to install and I am hitting close to 2100psi now.
Make sure to clean out all the crud from the housings. Be careful not to let dust/dirt drop in the pump housing on the car. As soon as I started removing the pump, about a 1/16" out I could see dirt wanting to drop in. I stopped, pushed it back in and applied a little oil to stick the dirt down and stop it from falling in. Then I removed the pump and cleaned up the dirt.
The install was not horribly difficult. Getting the high pressure line disconnected from the bottom of the pump was the hardest part due to the small amount of room available. I would suggest buying a set of stubby wrenches. The tappet isn't as easy to set as the video shows. I had to use more force to get it seating. I did use a screw driver handle but had to give the opposite end a few love taps with a hammer(not too hard). Reinstalling the pump went well once I figured out it was easiest to run the pump bolts down about 3/4 of the way then reconnect the high pressure line. I wasn't able to connect the line once the pump was bolted in all the way. I will only rate the internals 3 stars for now just because I haven't had a chance to beat on my car yet, but the internals themselves look like they were made with good materials and are nicely machined. I will come back and rerate once I have driven a few miles. On a second note, having made several purchases already, everything I have purchased from Corksport seems to be very good quality.
This definitely took a little longer to install them I thought but the results are incredible. The car runs much smoother, power kicks in quicker and is well distributed across the RPM's. Noticeable increase in power and now I have the piece of mind of finally having this and knowing that my car is ready for the big bad downpipe. Stop wondering if you should buy this and just do it! It's worth it and you need CORKSPORTS version which is the absolute best! Thank you Corksport!
These internals are just as good, if not better than the popular Autotech and come with easy to read and follow instructions. Great pressure at WOT and I'm completely confident in this part. They sold out when I ordered mine and I was worried I wouldn't get them in time for dyno day at the local Mazda shop. I emailed Brett and told him this, and he reassured me they would make it in time. A few days later I get an email with the shipping tracker, and they had upgraded my shipping to priority at no extra charge. Amazing customer service, I will continue to spend all my money at Corksport! Thank you guys!
a bit expensive especially for how small the parts are, but feels so much more smoother and responsive saw a max fuel pressure of 2059psi on my access port, max i hit before was 1857psi , took me a hour and 15 to do it and clean out the crap from the pump put a clean oil film on everything and went together smooth
If you plan on modding your engine in any way, even if it's only a Stage 1 CAI, I recommend purchasing CorkSport's fuel pump internals. They are the gold standard and cheap insurance.

I've got 10k miles on mine with no issues and I have the confidence of knowing I can supply 1800+psi at WOT all day long.

The install was easy with two caveats:

1) A giant bench vise and breaker bar are very helpful.

2) On my car (2006 MS6), during removal, I could not get the fuel pump to clear the bottom fuel line no matter how hard I tried. I ended up finding a clamp securing the line to the engine block that needed to be loosened allowing me to lower the line a little so the fitting on the bottom of the fuel pump would clear. We're talking less than a millimeter here, but it would not come out for me without this step.

Finally, FWIW, I noticed zero noise difference between the OEM and CS internals.

As always, great job CorkSport!

Worth the price buy over all other brands. I had an autotech already installed not my choice obviously. I can speak first hand that corksport is better I logged a 4th gear pull WOT with the autotech results were 1,856 psi in the fuel rail. I ran the same test with corksport and the results were a peak of 2,001 psi in the fuel rail. Corksport internals hands down have a higher flow and send more fuel to the engine. This means more power and safer to run higher boost levels.
This is an addition that I didn't think I really needed, as I am not interested in doing any tunes or any of the mods that I read about on the forums, but I believed someone on a very rude and crude forum that the first mod for a Gen 2 should be to replace the fuel pump internals. So, OK, it was the 4th or 5th addition but WOW, I didn't expect the drivability differences these internals have made! My car now drives in such an amazing way. I am a Pastor, not a technician, so I will likely use the wrong terminology, but let me just say that from the start it takes less gas to start from a stop, and the acceleration is much smoother and more linear.

I am confident that following this advice is a good move on my part.
As with all CS products that I have bought the quality is second to non. Packaging is fantastic and between the YouTube install video and the detailed colour instruction the installation is easier then it looks. Took me about 2 hours including putting all my tools away. Take your time and this is a pretty straight forward install. Took it for a little drive and you can tell right away how much smoother the car is. Thank you CS for all that you do.
These parts are a NECESSARY evil on our engines. Buy them from corksport to ensure quality and quick shipping! Was everything I expected and more. I would recommend this upgrade to anyone looking to mod. As in do this first and be smart. They are expensive but well worth it. Not to mention is comes in a nice case (as do most CS products) as well as the tool used to install it functions as a keychain bottle opener. Always love cracking a cold one with my HPFP tool.. because its badass bro. Buy it
Excellent quality, best features on the market, and as always good tech support from the guys had a technical question and they followed up with me right away.
They're the best in the game, can't even compare how dedicated these guys are to other manufacturers. It makes me question why cp-e,cobb, and jbr didn't even make their own fuel pump internals. It's quality every time I purchase something here. They include everything you need and need to know.
Got them in and installed the same day! I didn't have any problems the instructions were on point and only took an hour to install. The price though for what the part really is isn't cool but you need them to keep modding your car and CorkSport did the best. And I noticed the gains instantly.
Easy installation. No issues with fuel pressure dropping out at high rpms. What more can you ask for?
My car performance is awesome with the new internals. Installing the internals is a little more difficult that the instructions or the video show. It is impossible to get to the fuel pump without removing the battery box. Also if you have the Corksport intake system installed, some of it is going to need to be removed. Other than that the install went well, it just takes a little longer than the 2 hours estimate.
Wow! What a product. Have done a lot of research about which internals to buy and everything kept coming back to corksport. Install was a breeze. Took about an hour and 10 minutes. Instructions were in great detail. I work for Mazda and showed our master Mazda tech the new internals and he was very impressed. Especially after I showed him the before and after data logs. Easily pushing over 2000 CFM's at WOT. HIGHLY RECOMMEND these internals over anyone else's. Great job Corksport
Install was simple took longer to get a torque wrench that to install. I was getting a cel for running lean at off idle but now that's gone and the car runs great. Thanks CS
Derek first of all I know Cody thank you for making it Superior product great fuel pump and it's amazing simply amazing great quality performance is unreal thank you for making awesome products
Easy installation, guide was very helpful. Car is running awesome with the new fuel pump.
Can you do an ots with the stock do pipe
Just got this HPFP installed with a fresh dyno and gained 15WHP! At the same time, i took out the butterfly in the intake manifold and also gained 20WTQ! This fuel pump is incredible people!
I received my CS HPFP internals last week and installed them this past weekend (October 3rd). It took about 4 hours going very carefully. I parked my car Friday night and when I opened the high pressure rail, nothing came out at all. I didn't use relays to cut off the fuel; I just shut down normally the night before. Results may vary! For the 19mm nut, I used a tie-wrap, as suggested in the excellent Youtube video provided by CS that I watched 2x before starting the job. 1 hour of my time was spent with that high pressure line both when trying to slide out the pump and later to slide it in. It seemed like the unit wouldn’t come out, but the problem was just that it is low-tolerance and the force of the high pressure tube was causing the unit not to slide out easily. I pushed down that rail and the unit came straight out. Then straight in, but pulling the tube back up was painful. My setup is all Corksport SRI/TIH, HPFP, and TMIC. I’m using a Cobb with a stage 1 map for the Corksport SRI/TIH and 91/92 Octane, to which I always add $3 O’Reilly octane boost, just for some added margin. The car is smoother and faster and pulls harder to redline. At first I thought it was just the post-mod feeling, but after driving for almost a week, I noticed all kinds of differences in how the car pulls in all gears and all speeds. It really is running better with the exact same map I’ve always used. Now I just wish Corksport made Accessport maps for its own mods so I could take better advantage of the better flow from the TMIC with their intake and HPFP. I guess you can’t have everything.
I just finished installing this last night on a gen2 MS3 (it took about 1.5 hours with help from a friend). I definitely recommend having a friend help, as reinstalling the pump housing and lining up the high pressure fuel line would have been nearly impossible by myself. The majority of our time was spent removing and reinstalling the pump housing. Assembling the internals is a piece of cake - thanks to the clear instructions (I watched the video and read the print instructions twice before installing) and provided tools. The car fired up on the first try with no leaks. Thanks CS for a great quality product!
The fuel pump comes packaged very nicely with well designed tools and amazing instructions. Install was easy, just take your time and have fun. The results were very noticeable with instant smoothing of the raw feel these cars develop. It's still there, just more eager and stout than before.

Save up and spend the money to buy this, it's worth it, and provides ease of mind for later mods.

Corksport is the model by which all companies should strive to be, however them not following in suite is what makes me keep coming back for more.

The customer service is spectacular, when I call with questions I get to speak to an engineer. Being an engineer, there is nothing more frustrating than sales people BS-ing their way through your questions to get to the gold. This is a company that builds a relationship with their customers, does what they can to help them, and build great products because they care.

I got my CORKSPORT Max Flow Fuel Pump Internals installed today. Oh man! I have only driven 5 miles on them and I already feel the difference. Seems smoother so far.

My car has 129k+ miles. On my stock internals, I maxed out at 1735psi, but it didn't really hold and it was high up in the rev range. Still pretty damn good for that many miles and all the mods I have. But, when I want more, I want my car to be safe.

After the install I noticed that I was hitting 1700psi+ while I was keeping the RPMs well below 3500 RPMs!

Can't wait to open that throttle. I want to take her easy for about 100 miles before that though. Thanks Corksport!
Im Hitting 305 HP right now and fuel pressures maintain at 2000psi. Proven reliable.

Last review was a fluke. Forgot to click star rating. Hopefully it doesn't get posted.
The difference between CorkSport's internals compared to the stock internals is night and day. The car feels a lot smoother when you do pulls and it stays aggressive even when you're hovering past 5K on the tac! The install itself was easier than I thought too and the video that CorkSport has on YouTube was really helpful along with the paper instructions. One thing I suggest you do is pull the CIRCUIT fuse in your car and then start the car and let it idle until is dies. I've seen other people do this and their car dies within a few seconds after they turn it over but my car took about 30 seconds until it died so just give it time. Doing this will release pressure and help you loosen the 19mm nut that's on the fuel line. During the actual install of the internals just follow the video and you'll be fine. You don't need gloves when installing the internals, but if you want to wear them then go for it. I personally just had a lint free towel on my kitchen table, a foam pad to put my vice onto, a cup of clean motor oil and a cup of some gasoline from the fuel pump housing, my laptop with the install video on and clean hands. The assembly took about 5 minutes and was pretty simple. When it was time to put the housing back onto the head the fuel line was too high up and causing the housing to go onto the head at a weird angle. After I noticed what was going on I called up my buddy and he pulled the fuel line back as I put the housing in. I definitely recommend two people when you install the housing back into the car because if your fuel line is like mine then you cannot do it alone. After the install I let the car idle for 20 minutes just because I was putting the tools away and getting side tracked by TV. I did take it easy on my car for 100 miles like you do with other internals and not go over 4K just because I wanted to play it safe. Earlier tonight was when I finally went past the 100 mile period and I did my first 3rd gear pull with the new internals. Someone said the car feels like a missile with new internals installed and I have to agree with them. It's also a great feeling to know that I can safely install a downpipe now!
I am running a fully bolted 2007 speed 3. on a stock turbo at 21lbs peak target

through AP. and 3.5 FMIC over my Top mount ETS 3.5

I ran it last year and she struggled to maintain pressure at wot around 5k in 4th and 5th and 6th gear.

Just installed sunday after being one of the first to purchase the CS internal upgrade.

Yes i was intimidated.

Install was easier than i thought and wow. What a seat of the pants difference. smooth till redline in every gear. did my datalog wot to 130 at 21.36lbs peak and all parameters are fantastic.

Should have been my first mod if it was available.

My first mod was the CS MM insert. I should have known then , these was an engineered product !

Best mod ever.

wow. just wow

for anyone who is going to turn up the wick hard on a speed 3 this should be your first buy.

peace of mind.

These folks nailed it.
I mean CorkSport just hits the right note with every product. This was the install I feared the most. In reality it was very simple just make sure to take your time. I would recommend a 2nd pair of hands with putting the pump back in. Install time was right around 45 min to an hour for me and my brother. If your looking for a HPFP then look no further.
Very good product. Install was actually pretty simple. Getting that 17mm and 19mm to loosen up on the high pressure side was a little difficult. Don't be afraid of this install, just watch the video and you will be okay.

The car pulls a lot smoother now, there is no more "step". Once you get into the high end it pulls more. Gotta have the Cobb AP with this. I have Cobb AP, CS SRI/TIP, CS RMM, and CS HPFP and its running like a champ. Overall great product and really gives your car that power that you want.
Hi corksport I just ordered my fuel pump internals just this last Wednesday and I got it Saturday even with the cheapest shipping I got everything super fast I'm really happy. But one complaint I didn't get the installation tool with it ? Do I need that or can I install it without that part?
Pro Tip: Get an electric impact gun from harbor freight tools for 40 bucks and thank your self when you don't have any problems taking off the locking nut on the internals. Until I purchased this, doing this job was a challenge to say the least because you need to push down quite a bit over the factory spring to reach the nut itself and then twist. Neither the provided instructions nor any online videos tell you this explicitly. With an impact gun, its push down and pull the trigger, done.

That aside, I did all the data logging on this during quite a few WOT pulls and the fuel pressure held extremely stable right where it should. Working towards a stage 2 tune, I knew this piece was necessary and it definitely does what it says it will do. I also really like the fact that CorkSport provides all the needed tools to install this easily ... and man, that box it comes in ... so cool, I still have no idea what will have the honor of going inside it yet.

One quick thing I would mention: When I first installed this ... I was scared because the fuel pump seemed much louder than stock. Good news is that this is normal because the spring has more tension and after a 100 miles of working it in, the sound dies down. So if you install this, freak out because it makes a loud rhythmic ticking sound, fear not, its all good. Grinding or arhythmic sound ... pull it out fast, something went wrong.
One of the best purchases I've made for my Speed3. I was going to wait until I had my AP before I installed these internals, and I wish I hadn't waited. I have my AP ordered and on the way, so I installed these in preparation. I could feel the difference as soon as I started driving. The response and ability to maintain power through the entire RPM Range is 1000 times better now that I installed these. Normally I would feel a dropoff in power around 4000 RPMs, but I feel no dropoff at this point. Finally, my engine can keep up with the weight of my foot.

Corksport SRI, Racing RMM, Internals installed.. TIP, AP, Downpipe coming soon.

Thanks Corksport!!
I got my CS stage 2 SRI prior to getting the fuel pump internals and I can feel a difference after installing. Got the AP already and now time for a Downpipe! Corksport is the best in quality and shipping time!! A++
Hi CS team!

I've installed the internal, but I also have heard that I need to wait some miles to drive the Car at full throttle.

It is true? If so, how many miles do I need to wait?
Do you need the access port to tune your car after installing the hpfp internals?
Love this part! Made a big difference in my speed6
I too had my TMIC off during the installation (like Matt G.), and getting to everything was super easy. This was the installation that I worried about the most. But with CS's super instructions and the installation video, this installation was a piece of cake. I installed the CS DP during the same install, and with the 20% increase in fuel flow pressure...I am not worried about running out of fuel at WOT!
I have ordered a few parts from Corksport already for my car. When it came time to get the fuel pump internals i didnt think to go anywhere else. Came here right away. They make a great product!!!! Cant wait to get them in and get going.
Can you put this on a 2013 Mazda 3 Skyactiv? And what would happened if you do?

Check out the FAQ tab for this part for an answer.
Changing pump internals was pretty uneventful due to good documentation and kitted parts. Hardest part was getting to the pump which just requires some time and tinkering. My stock pump held up pretty well with stage 1 mods but looking forward to stage 2 mods while holding steady at 1670 psi. I've accumulated about 1K miles on the mod and it's running perfect.
This item came very well presented. Instruction for install was very thorough and installation was a piece of cake.

Only recommendation is to remove the injector fuse and run the car till it shuts down itself before install. This way you won't have any pressure built up in the high pressure line and will not get sprayed with fuel.

After installation, the difference can be noticed straight away. Much smoother run and maintains plenty of consistent pressure.

Very happy with this product! A must have for all MS3! As always, a quality product from Corksport! Thanks!
Wow! I almost didn't want to take it out of the cool-looking black box, but here's my review...

Shipping and Packaging: A+

Shipping was fast as usual with, and I had this sweet setup in my hands within a couple days from ordering (figure VC to Chicago where I'm at). The shipment packaging was as expected: the cool box containing the good was wrapped in bubble tape and then nested in ruffled brown paper. That aside... holy crap that little black metal box containing the goods made me feel like I was opening up something out of National Treasure! CorkSport really didn't have to go to these lengths, but they did.

Quality: A+

Again with the great presentation. The internals come in a beautiful black metal box, components are stamped with serial numbers and vacuum sealed in plastic, it comes with a higher-grade spring, AND installation tools. Oh, and CS was nice enough to include an 8Gb flash stick with the instructions. You can then use the flash stick for anything! This beats the hell out of competitors on so many levels.

Installation Difficulty: 4 out of 10

This isn't really a hard install, but you MUST take your time! I was sweating this install for quite some time, but the CS instructions (I have some suggestions) and YouTube videos showing the step-by-step install made it a breeze. Take your sweet time, and seriously clean your hands when dealing with the actual internals. DO NOT force the internals piston into place. If the fitting is rigid and sticks, lube it with more clean oil. DO NOT force the HPFP assembly back into its seat! You might find that the lower line catches it. You will need to push it down so that you can properly jiggle the assembly into place. I had to take the assembly out because of the lower line pushing up against the assembly. You need to keep on playing with it.

NOTE: I did remove the TMIC for the installation. It seems like it really isn't needed (shroud only), but I did, and found that it gave more access to the HPFP assembly. You don't need to remove the battery.


You should really own an Cobb AP, in my opinion. I logged the HPFP before and after the internals installation. The peak on stock internals was 1720 psi at WOT, while CorkSport internals created 2098 psi on the same tune selection.


Please add instructions to pull the electrical fuel pump fuse to relieve pressure. Pull the LPFP relay, turn the car on, and then it idle until it dies. There is no need for pressure sprays of gasoline all over the engine. I did this for the installation, and it worked.
Hey guys just a quick note to say the Max Flow Pump Internals were fantastic. Installed over the weekend, instructions were precise the only difficult part was the high pressure line and pushing the pump back against the spring. But this is largely due to my poor mechanical skills.

Purchased via Jase from New Zealand :)
As some others have stated the packaging had me in awe after I openend the box. The quality seems top notch and went in easy as pie! Holding 1800-1900 PSI on stage 2 with no issues so far. As a side note, the tappet came pre installed so you can skip that step!
Have had these and the racepipe installed now for couple weeks and I love them no complaints 2000 wot psi levels and 1800 steady flow no problem. downpipe going in today.
The packaging of this product blew my mind, no other company provides this level of craftsmanship combined with the feeling of purchasing an exclusive product. The white paper sold me on this product and i am happy i purchased. I hit psi levels over 2000 at WOT, but more importantly it is flowing more volume than stock. Install was easy and the pump makes less noise than the stock one. You do not need to be a master mechanic to do this job yourself.
Jut did the install today. Wow,what a difference! There is a seamless pull throughout the powerband. The CS internals made one hell of a difference. This a 'must have'! Thanks Corksport!
This internals are great. Been on them for 600+ miles already and have kept pressure. The packaging is great as well. The shop that I got it installed usually uses the competitors stuff and where very impressed with with this kit included accessories. Thank you CS for a great internal kit...
What modifications to the map should be made after installing these internals. You have OTS maps for the internals, but the directions do not include how to tune for these. Are pressure targets and injector phasing going to be the same for these?
Can you tune with these pump internals with a cobb access port v2?
Just installed tonight in 2hrs just as expected. I am no mechanic, but I make it by. Got your SRI, RMM, AP and now the internals...quite happy. Exhaust is next. One "tapper" came already installed to the that a new thing? kind of threw me.
This upgrade should be the first thing to do. The car's power is so smooth and linear now... Great product and upgrade. If you are thinking about it... I'll make it easy for you. Get this upgrade because you will not regret it. Thanks Spencer for your Tech Support.
IMO, you should add maps for your 3" SRI to the others linked from here.
I've got to say I'm very impressed. I was expecting more power but what I wasn't expecting was how much smoother it would be. I'm super happy and only regret not doing it sooner. Oh and it comes with a thumb drive and a nifty install tool that doubles as a bottle opener for your beer when you're done! Corksport you know where my heart is, fast cars and beer.
will i need to get my mps6 mapped when i fit my hpfp many thanks corksport
Hey guys just purchase this fuel pump internals,was debating for a long time between autotech and corksport.

I had to go with corksport

Was wondering if I just install this on my stock motor with no other upgrades do I need a tune?
I see you there, sitting at your computer wondering "should i buy these fuel pump internals for my mazda?" STOP WONDERING, BUY THEM NOW!

These are easy to install, hold that fuel pressure, and look sexy as all get out!

Seriel numbers? BAM got them, Awesome instructions? BAM, got those too! 1700 psi? Forget about it!

Do the right thing for your mazdas performance and buy these asap
Installed these this afternoon. The instructions were spot on. Felt an immediate difference in the car. Pulls smooth and linear, no "step" as i call it in the delivery. Great product and great service also. Spencer called to confirm the order and let me know on the build out delay, all understandable, answered the few questions i had about these mzr motors. thanks guys will be ordering more products in the future.
Guys I need help with a custom tuner in my area. Please let me know. Miami Fl 33126. Thanks in advance.

CorkSport Reply: We would highly recommend doing an E-Tune with any of the wonderful E-tuners that support our Mazda platform. Some great ones we recommend are Stratified Tuning, RichTune, and FreekTune
got loads of mods from corksport cant wait to fit hpfp on my mps6 love corksport spencer
CS, How does this product compares to Cobb's?
If I plan on installing your stage III intake with TIP, test pipe, and catback exuahst, should I also upgrade the fuel pump internals as well? I know it is needed with the down pipe.
Great product! The installation was painless and straight forward. The pressure hold very and is extremely consistent. These internals are a must have!
First time buying from CS and I have to say best customer service I've had in a long time spencer is awesome and has a great deal of tech knowledge. I could'nt be more happy with my new HPFP I'm glad I made this choice over the Autotech. Thank you CS

Great Product thus far also shipping was great and quick only complaint was I ordered this with a rear race motor mount and got one corksport sticker in white and one in silver wish I had 2 silvers to put on the rear side quarter windows
Great Value for the price! I have one question, I am just starting to mod my Speed3 and am wondering if this is safe to install without a AP? My AP will arrive later on.
Glad I waited for these! Installed in under 2 hours and WOW what a difference in power. Now time for a freek tune!
Had these installed the 14th, tracked on the 16th no issues! Thanks guys!
Put these in today. Took battery out for easier access to 19mm nut. Very pleased. Installed within 1.5 hours and that is with breaks. No more safe mode :-) Thanks CorkSport.
Just installed these, pretty easy except the little nut thingy was already pressed in that washer. Install into the car was tricky because you have to play with that 19 ml socket line. Any ways I got it and it runs great! Thanks CS! What's the break in time before WOT?
Just litteraly ordered these internals snd the ap v3 from you guys...wasnt kidding when i said i would order them right when it hits midnight. Cant wait to install!!
Do you have to slowly break it in? or after installment you can wot?

CorkSport Reply:Give them ~100 miles.
I have a 2013 Mazdaspeed3 and I want to do some small upgrades, such as; SRI or CAI and a CBE. I want to keep my car as stock as possible but I want to have some fun at the same time. The problem is that many people from the forums are telling me that I have to at least upgrade the HPFP. Is that correct? Again, I don't want to change the turbo inlet or the downpipe, just the intake air box and the exhaust system.

CorkSport Reply:Give us a call 360-260-2675
Looking forward to purchasing this kit. Seems to be the best kit out there for the MS3.

Is there a significantly negative impact on MPGs when compared to the OEM pump internals? I would be running the Stage II SRI, TIP TMIC and, in the near future, CBE .. All corksport.

CorkSport Reply:Give us a call 360-260-2675.
I'm glad I held off on buying internals until these came out, they were worth the wait. Glad to see Corksport use the OEM spring keeper too unlike autotech.
By introducing higher pressure levels to an already high-pressure system, how much does this increase the risk of blowing seals/decreasing reliability of OEM fuel system components?

CorkSport Reply:There is no side effects from running more volume in the system. Give us a call for details 360-260-2675.
Such a great investment opened the car right up. Anybody who is skeptical to buy shouldn't be works great And corksport has always delivered top notch parts. Here comes the dp and cbe!
Awesome product, install was painless and the pressure holds very well, pulls also feel very consistent. I highly recommend these internals.
Great product just installed mine today worth all the money so FREAKIN HAPPY that it's works they way it's suppose too

My foot has lost so much weight....waiting for this....just saying...
Im going to buy a CS SRI stage II and a Cobb AP. when I was checking you guys stage I maps for the AP says it is recommended to upgrade the CDFP. Will this piece do the job?

im sorry if this is a question I should know, I'm new at this.... thanks!!!

CorkSport Reply: A stage I MAP with our intake should be fine. The best way to know for sure is to log your fuel pressure.
So this is kind of like the autotech high pressure fuel pump ?

CorkSport Reply: It is similar, but we include: Full Color Install Instructions, Full Install Video, Customer Accessport Maps, Specialized Install Tools, and it is the only pump made specifically for the Mazda MZR engine. Take a look at the chart above for more info.
WOW I cant wait.. I was gonna go with the CP-E unit but the price and the benefits it seems you guys did with it are impressive. All the extra features are a plus. I cant wait till tax season

I went to install these internals and noticed that the little O-ring that the piston passes through had degraded in my stock pump. Any ideas short of buying a new pump would be greatly appreciated?!?

My HPFP makes a loud clicking at the lightest touch of throttle between 2000-3000rpm. I've had CS internals in the hpfp for about 4 years. I replaced the fuel relief valve and even put in new CS HPFP internals and the problem persists. Does anyone on your team know the issue I'm experiencing and how to resolve it?

I'm assuming that with the tappet already mated to the collar there is no further seating required? This is the only step in the process that differs from the instructions.

Hello, I installed the corksport internal in a brand new hitachi pump in my gti mk5 fsi engine 2008. The stock pump works perfectly fine, however with the corksport internals the car would have difficulty to start, like if the pump is not primed, and when the car does start the ecu throw the code p2293 Fuel Pressure Regulator 2 Performance code, and the car appears to be a limp mode. No boost no power. Apparently the car is experiencing fuel starvation. When I put back the stock internal in the pump, everything is normal. Any suggestion? Should I try with the stock spring?
