Fuel Supply Manifold Assembly
The fuel supply manifold assembly delivers fuel at high pressure from vehicle fuel supply line to injectors. Assembly consists of 2 banks of stamped fuel rails connected by a crossover connection (5.0L engine), or 2 preformed tubes or stampings, one for fuel supply and one for fuel return (2.3L and 2.9L engines). On 3.0L and 4.9L engines, the assembly consists of a single preformed tube with one connector for each injector.
Fuel pressure manifold assembly has injector connectors and a mounting flange to fuel pressure regulator. It also has mounting attachments which locate fuel manifold assembly and provide injector retention. On 2.3L, 2.9L and 3.0L engines, a fuel pressure relief valve is installed on fuel supply manifold assembly to release fuel system pressure.
