APR 19-25 Audi Q3 2.0T Gen 3 High Pressure 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 A3 15-20, Q3 19-24, S3 15-20, TT Quattro 16-23, TTS Quattro 16-23; VW Arteon 19-21, Atlas 19-23, Atlas Cross Sport 20-23, Golf 15-18, Golf Alltrack 17-19, Golf R 15-19, Golf SportWagen 15-19, GTI 15-21, Jetta 19-24 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.
