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.

Frequently Asked Questions
What are the symptoms of HPFP seal failure?
Common symptoms include fuel smell inside the motor, cold starting issues, and warm starting issues due to pressure loss and fuel seepage.
Will this kit work with aftermarket fuel pumps?
This kit has only been verified on OEM pumps and may not fit some aftermarket pumps. We recommend checking compatibility before ordering.
Do I need this kit if I'm upgrading to larger HPFP pistons?
Yes, upgrading to larger pistons can overstress and tear the factory seal. Our reinforced seals are designed to handle the increased pressure from piston upgrades.
What makes the Molybdenum Disulfide seal better than OEM?
The Molybdenum Disulfide construction provides enhanced durability, superior friction resistance, and maintains a perfect seal under high-pressure conditions that would cause OEM seals to fail.
