Fuel Pump

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 internal seals are replaced, including the spring seal, and the tip of the pump retains the factory pivoting head to reduce cam follower wear and piston side loading.Internal testing:All APR HPFPs are assembled in house under strict assembly guidelines. Each pump is then tested on our test rig to ensure the pumps operate as designed. This step is important for several reasons. It's critical in determining if a pump has a failure from incorrect install, a leaking seal, or a bad solenoid. Secondly, a seized pump on the vehicle at startup can cause damage to the engine's camshaft. By testing each pump, we all but eliminate these possibility.Proven track record:APR pioneered HPFP upgrades in the early days of VAG direct injection engines. Soon after, APR became an OEM supplier of HPFP and GDI components to VAG for use in various race cars, racing series, project cars, and concept vehicles. The APR HPFP has been at the center of countless motorsport victories across the globe and has operated with a nearly perfect tract record since the program's motorsport backed inception in 2006. With tens of thousands of pumps sold, APR has a wealth of knowledge, and manufacturing expertise necessary to deliver a product that will and has stood the test of time.OEM Components:Critical to the design of the APR HPFP is the use of only genuine Hitachi components, made in Germany, which consists of sensors, pump bodies, and other critical components that must operate with OEM levels of reliability. All APR components are made in the USA using medical grade precision machinery.
