Description

Overview

Disclaimer Does not fit some AFTERMARKET PUMPS.  These only have been verified on OEM pumps.

Over time, the factory high-pressure fuel pump (HPFP) seals in the Audi 4.2L EA113 engine degrade, leading to fuel leaks, pressure loss, and reduced performance. Additionally, upgrading to larger high-pressure fuel pump pistons can cause the OEM seal to tear, resulting in fuel seepage and oil contamination inside the engine.

The TGK Motorsport HPFP Internal Seal Rebuild Kit is engineered 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 wear and scouring 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.

Do I need this kit if I'm upgrading to larger HPFP pistons?
