Fuel Rail: Description and Operation

Fuel Rail:

The fuel rail is mounted on the intake manifold and consists of two steel distribution pipes connected by a non-replaceable reinforced hose. The fuel rail performs the dual functions of supplying fuel to the injectors and providing the necessary brackets and fittings to mount the components to the engine. Fuel enters the fuel rail at the inlet tube, proceeds to the six fuel injectors, and the fuel pressure regulator, and returns to the tank through the fuel return line. The fuel rail is under constant pressure and fuel pressure release is required prior to servicing. The fuel rail and hoses are not repairable and must be replaced as a unit.
