The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 41% over stock! In doing so, the direct injection fueling system is capable of satisfying...

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...
