APR High Pressure Fuel Pump - 2.0T EA113

Direct Injection Fuel Pump; High Pressure; 40-95 PSI Low Pressure; 158 Horsepower At 3000 RPM; 4 lbs.; w/Stainless Steel/ Heat Treated Piston And Bore;

The FSI fuel pump increases the volume of fuel from the high pressure pump by over 40%. Simplified, this is achieved by modifying some key internal parts within the pump. FSI pumps have been track tested since 2006 with several hundreds of thousands of miles of combined usage. Each pump starts out as a brand new OEM pump and is then modified with the new components by and undergoes a rigorous testing process on our high pressure fuel pump tester. Once a pump passes our standards it is serialized and shipped to the customer. A low pressure fuel pump, which varies from 40-95 PSI, delivers fuel from the gas tank to the high pressure fuel pump. Then the high pressure, camshaft driven pump pressurizes the fuel to upwards of 130 bar (almost 1900 PSI!) in order to spray fuel directly into the combustion chamber. Unfortunately on cars that have many modifications, the stock fuel pump cannot flow enough volume of fuel to maintain the system pressure and the car suffers from the familiar 'fuel cut' that so many modified customers experience. The limitation of how much volume of fuel the high pressure pump can flow is dependent upon the volume displaced by the pressurizing cylinder inside the pump and the number of times the piston reciprocates inside that cylinder. Since the high pressure pump is driven off of the engine camshaft by a three lobe cam the piston of the pump cycles at 1.5 times the engine rpm. (Engine camshaft turns at one-half engine rpm multiplied by three for the number of lobes on the high pressure cam lobe). Due to this dependency on engine rpm for the high pressure fuel pump output volume, the FSI pump is capable of flowing almost 370 HP at 7000 RPM but only 158 HP at 3000 RPM. The graph below illustrates the maximum horsepower potential of the stock fuel pump compared to the FSI fuel pump.
