APR 17-23 Porsche Panamera 2.9T/3.0T High Pressure Fuel Pump - Rebuild

The HPFP internals must be machined to extreme tolerances and installed in a clean environment or the pump can easily fail. Dimensional tolerances on the APR HPFP are as tight as .00004" and geometric tolerances are as tight as .00005". The plunger and barrel are created from certified and heat-treated bearing-grade stainless steel and the plunger undergoes a special diamond like coating process for exceptional surfaces hardness and ultra-reliable operation. To prevent float associated with altering the plunger's mass, APR supplies each unit with a properly specified spring. All necessary internal seals are replaced. Fits Audi A6 19-24, A7 19-24, A8 20-24, Q7 19-24, Q8 19-24, RS5 18-24, S4 18-24, S5 18-24, S6 20-24, S7 20-24, SQ5 18-24; Bentley Bentayga 20-24, Flying Spur 22-24; Porsche Cayenne 19-23, Macan 19-24, Panamera 17-23 Please note, this is an upgrade of your existing pump and requires sending a pump to APR to be rebuilt. The pump and solenoids must be in working order. We will test the solenoids and visually inspect the pump. Failure to package the pump properly can easily result in damage to the pump's solenoid connectors. For proper operation, the ECU must be updated with compatible software. B9 RS5 Stage 1+ Software available.
