APR High pressure fuel pump Audi TTRS 8J 2.5 TFSI



The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 30% 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. 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 145 bar, depending on factory parts, with the HPFP.


Finally, high pressure fuel is delivered to the injectors, which spray directly into the cylinders.
