into the fuel tank.
z a 1/8 turn fuel tank filler cap.
z a fuel filter providing filtration to protect the fuel injectors.
z a single fuel line accommodating the returnless fuel system.
z a fuel injection supply manifold which contains a differential pressure sensor and a fuel
temperature sensor.
z a fuel pump and sender assembly which provides pressurized fuel to the engine and contains:
„an inlet filter.
„ a check valve which maintains system pressure after the pump is shut off.
