Fuel Rail: Description and Operation
Fuel Rail Assembly
The fuel rail is a steel distribution pipe with mounting points for the fuel pressure regulator, 4 fuel injectors, pulse dampener, and injector wire harness.
The fuel rail performs the dual functions of fuel supply to the injection components, 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 4 fuel injectors, then to the fuel pressure regulator, and dampener,
and returns to the tank through the fuel pressure regulator. The fuel rail is under constant fuel pressure and fuel pressure release is required prior to
servicing.
