- a fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- a quarter-turn fuel tank filler cap.
- a fuel filter providing filtration to protect the fuel injectors.
- fuel tubes.
- a fuel pump and sender assembly which provides pressurized fuel to the engine and a signal to indicate fuel level to the instrument cluster, and contains:
