Fuel Sub-System

Fig. 1 Fuel delivery sub-system:

The fuel sub-system consists of a high pressure electric fuel pump which delivers fuel from the fuel tank, a fuel filter, fuel charging manifold assembly, a fuel pressure regulator and solid and flexible fuel supply and return lines.
The fuel charging manifold assembly incorporates electronically controlled fuel injectors. One injector is mounted directly above each intake port in the lower intake manifold. All injectors are energized simultaneously and fire once every crankshaft revolution.
