Fuel Rail

Fuel Rail:

The fuel rail design utilizes top-feed fuel injectors for fuel delivery. The fuel rail attaches to the intake manifold without the use of bolts.

The fuel rail is mounted to the top of the engine and distributes fuel to the six individual fuel injectors. The fuel is delivered to the fuel inlet tube of the fuel rail by the fuel pipes. The fuel then goes through the fuel rail to the fuel pressure regulator. The fuel pressure regulator maintains a constant fuel pressure at the fuel injectors. Any fuel in excess of the injector needs flows through the pressure regulator assembly to the outlet port of the fuel rail and through the fuel return pipe to the fuel tank to begin the cycle again. The fuel pressure can be observed using a fuel pressure gauge at the fuel pressure gauge connection.

An 8-digit identification number is stamped on the fuel rail assembly. The model identification number contains the Julian date, the year, and the shift. Refer to this model identification number if any service or a part replacement is required.
