APR High Pressure Fuel Pump Rebuild - Audi/Bentley/Porsche EA839 2.9T/3.0T
The factory HPFP on the EA839 2.9T/3.0T V6 is a common failure point, and APR's rebuild service returns it to spec with tighter tolerances than OEM. SKU MS100211 covers the rebuild using bearing-grade stainless internals, giving your fuel system a genuine second life instead of a costly replacement.
This listing covers the HPFP rebuild service for Audi, Bentley, and Porsche vehicles fitted with the EA839 2.9T or 3.0T V6 engine. Exact model and year coverage should be confirmed via the tabs above before ordering.
Note: This is a rebuild service for your existing pump core, machined and assembled in a controlled clean environment. It is not a new replacement unit.
