Fuel Rail: Description and Operation

Fuel Supply Manifold:

The fuel supply manifold delivers fuel to the fuel injectors from the fuel tank, fuel pump, and the in-line fuel filter. The fuel supply manifold consists of a single preformed tube with four injector connectors, a mounting flange for the fuel pressure regulator, a pressure relief valve for diagnostic testing or fuel system pressure bleed down. Also attached are the mounting flanges which position and hold the manifold in place and provide for fuel injector retention.
