Section 03-04A: Fuel Charging and Controls, 4.9L Engine | 1996 Vehicles Equipped with 4.9L SFI Engines Workshop Manual |
The fuel injection supply manifold (9D280) delivers high-pressure fuel from the vehicle fuel supply tube to the six fuel injectors (9F593). The assembly consists of a preformed tube for fuel supply and one for fuel return. The fuel injection supply manifold has six injector connectors, a mounting flange for the fuel pressure regulator (9C968), and mounting attachments which locate the fuel manifold assembly and provide fuel injector retention. The fuel injection supply manifold also is equipped with a fuel pressure relief valve (9H321) on the fuel supply tube.
