An electric turbine style fuel pump (2) attaches to the primary fuel tank module inside the fuel tank. The fuel pump supplies high pressure fuel through the fuel filter (1), past the fuel pressure regulator, and through the fuel feed pipe to the Fuel Injection System. The fuel pump delivers a constant flow of fuel to the engine even during low fuel conditions and aggressive vehicle maneuvers. The control module controls the electric fuel pump operation through a fuel pump relay.
