Fuel Delivery System
Fuel delivery system utilizes an in-tank electric fuel pump. Pump is integral with gauge sending unit. Fuel is pumped to the fuel rail through an in-line fuel filter. Fuel pump provides fuel at a pressure and volume exceeding engine requirements. Pressure regulator, mounted on the fuel rail, maintains a proper constant fuel pressure to the injectors. Pressure regulator increases the fuel pressure when engine vacuum decreases. Excess fuel is returned to the fuel tank through pressure regulator, using a fuel return line.
