TGK Motorsport High Pressure Fuel Pump Seal Rebuild Kit - Mazda 2.3L

Over time, the factory high-pressure fuel pump (HPFP) Base seal in direct injection engines degrade, leading to fuel leaks, pressure loss, and cold start issues. Additionally, upgrading to larger HPFP pistons—a common modification for high-performance and ethanol (E85) tuning—can over stress and tear the OEM seal, allowing fuel to bypass the seal and mix with engine oil.

The TGK Motorsport HPFP Seal Rebuild Kit is designed to fix factory leaks, replace torn seals from HPFP upgrades, and restore fuel system integrity. This kit also includes a replacement cam roller tappet, which is prone to scouring and premature wear when fuel leaks wash away lubrication. Whether you're performing preventative maintenance or upgrading your fuel system, this kit ensures optimal HPFP operation and long-term reliability.

Fix Factory HPFP Seal Leaks & Restore Fuel Pressure

One of the most common failure points in the HPFP is base seal deterioration, leading to fuel seepage, pressure drops, rough cold starts, and drive-ability issues. Additionally, larger aftermarket HPFP pistons put extra stress on the factory seal, causing tearing and fuel leakage. Our rebuild kit eliminates both issues by replacing worn or damaged HPFP seals with upgraded components, ensuring a leak-free, high-pressure fuel system.

Molybdenum Disulfide Seal for Maximum Reliability

A failing HPFP seal can cause fuel odors, hard starts, power loss, and potential fuel leaks into the engine bay. Our upgraded Molybdenum Disulfide Seal offers enhanced durability, superior friction resistance, and improved longevity, preventing fuel seepage and pressure loss even under extreme conditions. Whether you're running a factory setup or an upgraded HPFP piston kit, this seal is built to handle the increased fuel demands of high-performance applications.
