APR High Pressure Fuel Pump (HPFP) – EA839 2.9T & 3.0T

The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 37% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances. On the B9 2.9T they achieved an additional 37 AWHP and 50 AWFTLBS over their Stage 1 (E85) ECU Upgrade by adding the pump and running their Stage 1+ (E85) ECU Upgrade!

How the direct injection system works

A low pressure fuel pump (LPFP) in the fuel tank delivers fuel to the high pressure fuel pump (HPFP) at roughly 4 to 6 bar. Fuel pressure is then bumped up to a maximum of 250 bar, depending on factory parts, with the HPFP. Finally, high pressure fuel is delivered to the injectors, which spray directly into the cylinders.

The APR Solution

They dramatically increase the volume of fuel the HPFP can displace at every RPM by increasing the displacement of the HPFP by 37%. This is accomplished by increasing the bore diameter of the pump’s internal pressurizing cylinder. It’s important to understand, despite the name, a HPFP upgrade is not necessary designed to increase the engine’s fuel rail pressure. The primary goal is to increase the volume of fuel available, which will keep fuel pressure steady even in the most demanding of situations!

High quality components and extreme tolerances

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.

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.
