TGK Motorsport High Pressure Fuel Pump Seal Rebuild Kit - 2.9T/3.0T

Over time, the factory high-pressure fuel pump (HPFP) seals in Audi and Porsche 2.9T and 3.0T engines degrade, leading to fuel leaks, pressure loss, hard starts, and reduced performance. Additionally, installing upgraded high-pressure fuel pump pistons can stress and tear the OEM seals, causing similar fuel seepage and drivability issues. The TGK Motorsport HPFP Seal Rebuild Kit is designed to fix factory leaks, replace torn seals from HPFP upgrades, and restore fuel system integrity for both stock and high-performance builds.

Additionally, upgraded HPFP pistons—often used to support higher horsepower and ethanol blends (E85)—can cause premature tearing of OEM seals due to increased fuel system pressure.
