Mazdaspeed E85 Safe HPFP O-Ring Rebuild Kit

While HPFP internals are a common must-have mod for your Mazdaspeed, the rest of your HPFP is basically ignored. We aim to remedy that with the CorkSport HPFP Rebuild Kit for Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7 Turbo. Included in the kit is a brand new E85 safe O-ring or X-ring for every seal in the HPFP along with replacement stainless steel hardware to get rid of those annoying Torx headed screws.

The CorkSport Advantage

Mazdaspeed 6 high-pressure fuel pump rebuild kit

Reliability Focused:

Since even the newest Mazdaspeed 3 is rapidly nearing 10 years old, the rubber seals and bushings all over the car are starting to show their age. Avoid any potential issues in the HPFP with the CorkSport HPFP rebuild kit. Every seal in the HPFP is replaced with a brand new O-ring/X-ring so you can be confident that your Speed is ready to make power without causing issues with oil and fuel ending up where it shouldn’t!

Ethanol resistant Mazdaspeed Fuel Pump rebuild Kit

Materials & Testing:

With the MS3 and MS6 coming out right around the time ethanol mixes in gasoline were becoming more common, it’s hard to say if the fuel system was ever designed with ethanol in mind. The CS HPFP rebuild kit uses E85 safe materials to ensure your car will operate correctly and stay reliable whether you’re running pump gas with the standard E10 mix, an E30 mix, or even straight E85! We spent months testing various materials both on car and in isolated conditions to find the best fit for gasoline and ethanol blends.

OEM Specifications:

All replacement seals in the CorkSport kit are a direct match to the OEM seals. We even had custom tooling made for the X-ring that fits around the HPFP piston to ensure an OEM quality seal.

Hardware & Accessories:

The CorkSport HPFP rebuild kit also includes hardware to replace the security Torx and external Torx screws used on the HPFP. These are always a pain to remove, even on our zero mile engine, so why reinstall them? We even include a security Torx bit to make the removal that much easier! The CS HPFP rebuild kit comes with full color installation instructions which are a must as it’s very easy to get lost once you have the HPFP all apart.

The video was on point. Just know you might need minor changes when it comes to the autotech internal. Overall, it was a straight forward process. The upgraded filters is WAYYYY better than the OE plastic crap as I lost fuel pressure because of the PRV so I decided to rebuild the pump as well with this great kit. I recommend this to all Speed owners.

This kit comes with high quality parts that I was very impressed with. What was just as impressive was the detailed instructions that do not miss a single step and leave you confident in your install. Cannot recommend corksport enough!

If you are like me and have over 50k on your aftermarket HPFP internals, with most of that being an ethanol blend, you need this kit. Took longer than advertised to clean simply due to the fact that my internals were so gummed up. Every tuner needs to add this to their pre-tuning requirement list. Same as cleaned injectors and new spark plugs. 10/10

Definitely recommend doing this if running E85, or even just have a lot of miles on the HPFP, the instructions were very in depth, the only issue I actually had was the 2 filters on the fuel rail and in the relief valve. Other than that it was smooth. Thanks CS

Any follow up on this kit working with the CP-E pump?

I'm thinking of getting HPFP internals with this aswell, I don't know if that is a good idea or not becuase I'm new to all of this. I was also going to replace the spark plugs before upgrading my car because I don't know the last time they have been changed. But my other question is am I still able to use 91 octane with this or is there no point in installing the rebuild kit if I'm not gonna use E85 and I should just stick with only spark plugs an internals.

With an upgraded E85 safe intake fuel pump, could you run full e85 with this rebuild kit?

Do you recommend using chlorinated or non-chlorinated brake cleaner when cleaning the individual parts of the HPFP housing?
