Mazdaspeed High Pressure Fuel Pump Internals

I installed this on my 11 Mazdaspeed3 and for some reason the car goes now rich, STFT is always -7 to -12.50, Replaced Maf, inspected MAf wiring, claps, TB gasket replaced, replaced TMIC with CS TMIC, stock intake/Inlet tried Silicone Inlet+ Custom Intake. When i removed and installed the OEM one values were back to normal, does this need any kind of tune?

should I get the MPS HPFP internals from COBB or CorkSport? what are the differences? is the CorkSport HPFP compatible with the COBB accessport?

Is there a way to order just a piston and tappet or do I need to order whole new set of internals?

i bought a used 2008 mazdaspeed with the corksport hpfp internals already done as of late ive had to order a new oe fuel pump to replace it. can i reuse the hardware i have here and order rebuild kit or do i need new internals.

ive been doing some reasearch here and there, checking forums and all that but i cant seem to find a direct answer. If i buy this hpfp will i need to pair it with some bigger injctors ?

Does it come with a warranty?

Will this work with a CX30, and if not is there a model meant for those specifically? Thank you!

Will installing your hpfp internals make it so my car wont pass smog?

Just purchased a 2010 Mazdaspeed3 with 135,000 miles on it. The car came with a Cobb SRI, but everything else is stock. The next step is to install high pressure fuel pump internals. Will replacing the internals on a high mileage car be fine with the existing fuel pump or should I replace the whole fuel pump and place the high flow internals in a new high pressure fuel pump?

I have a fully stock 2010 speed 3 just lowered it and i need more engine upgrades so will i need a new MAF or tune when i install this?

My current stock hpfp is ticking, will this also fix my hpfp or should I get a new one first and then buy this kit?

First mod of many; can I have my local mechanic do the install?

That will work for Mazda 3 2013 2.5 auto trans (non skyactiv)

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 have a 2006 Mazdaspeed 6 and there is a Service Bulletin 01-022/08 for engine too lean at idle (P2187) will the fuel pump kit fix the weak fuel pressure at low idle?

can i run a sri and cbe with the stock tune?

I have the stage 2 intake and rmm insert, I don't WOT, go to tracks or race, I just use my car as a dd and I just bought the intake because I read that it would help me save on my mpg. Do I really need to upgrade my HPFP? Thank you

I upgraded my pump internals with the CS high flow fuel pump internals. I'ts possible revert the pump internals to stock, with the same stock internals removed?

Is this compatible with gen 2 (2009~2013) speed 3?

How much does this effect the fuel mileage?

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.

I'm running stage 2 intake, boost tubes, and race pipe. Would I be safe for awhile while running theses mods. Still saving for the fuel pump

Can I run a stage 1 map on my 2013 mazdaspeed 3? Mods: corksport sri w/TIP, corksport cbe.

My internals came with the tappet already mated to the collar. Is any further seating needed or just slip on? Sorry if this shows up twice, I got a send error the first time.

Can you do an ots with the stock do pipe

I've been told this should be the first upgrade to my ms6 before anything, true? I already have exhaust and short ram intake.

I feel like im beating a dead horse here but do you need any specific map to run this HPFP?

Is there any sort of break in period needed or recommended after the installing of this pump?

I bought and installed the HPFP and my relief valve blew. Im buying a new relief valve and need to know what the peak pressure the pump will make so buy the correct relief valve. Thank you in advance P.S do you have any advice on the relief valve?

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?

At wot sometimes cuts my fuel like a fuel cut would I need internals?

Wat advantage does this have over an entire hig pressure fuel pump? Stock Speed6

this works for mazdaspeed3 2007-13 correct?

Would this work with a 2014 Mazda 3?

These will work on a 2010+ ms3 right?

What should my fuel pressure be at wot/cruise/idle. Im running stock internals with stage 3 corksport cai and inlet pipe. Also running the cobb stage 1 91 cs cai+inlet. Running 1700 at WOT. I need to upgrade just gotta save up. Am I safe or should I down the map to safe mode?

Would this also fit the fuel pump in a VW/Audi FSI engine?

Do you need an accessport for any changes after install, or is that optional tuning.

Does this work with 2012 Mazda 3 2.0?

After install the internal, do I need to avoid driving full throttle?
