The APR High Pressure Fuel Pump (HPFP) dramatically increases the maximum volume of fuel the HPFP can deliver. In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower turbocharger systems, such as APR’s Stage 3+ EFR7163R ROW Turbocharger System for the MK7 Golf R, S3 and similar vehicles.
