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 modifi
