a. The fuel system includes the following which are integral to the engine fuel injectors, fuel pipes and a

fuel manifold. The external components of the fuel system are a fuel filter, a fuel strainer, a fuel pump and fuel

Leaving the pump under pressure, the fuel is forced through the fuel filter and into the inlet fuel manifold, then

through the fuel pipes and into the inlet side of each fuel injector.
