Audi A6 High Pressure Fuel Pump - APR - Rebuild for 2.9T and 3.0T EA839 V6 (2019-2024). This service rebuilds your factory Hitachi Gen III HPFP to support higher fueling demands with OEM-level reliability.

APR increases the pump’s displacement for roughly 37% more fuel volume than stock, helping stabilize pressure under heavy load, larger turbo setups, and ethanol blends. Internals are precision machined to 0.00004 in/0.00005 in tolerances from heat-treated bearing-grade stainless, with a DLC-coated plunger and a weight-matched spring to prevent float. Each pump is assembled and bench-tested in-house. Compatible ECU software is required. This is a rebuild of your working pump; you will send your unit to APR for the service.
