RAM 1500 Truck 4WD V8-5.9L VIN Z (2002)
Fuel Rail: Description and Operation
The fuel injector rail is used to mount the fuel injectors to the engine. A fuel pressure test-port is attached to the fuel rail.
High pressure from the fuel pump is routed to the fuel rail. The fuel rail then supplies the necessary fuel to each individual fuel injector.
A fuel pressure test port is located on the fuel rail. A quick-connect fitting with a safety latch clip is used to attach the fuel line to the fuel rail.
The fuel rail is not repairable.
CAUTION: The left and right sections of the fuel rail are connected with either a flexible connecting hose, or joints. Do not attempt to separate the rail
halves at these connecting hose or joints. Due to the design of the connecting hose or joint, it does not use any clamps. Never attempt to install a
clamping device of any kind to the hose or joint. When removing the fuel rail assembly for any reason, be careful not to bend or kink the connecting hose
or joint.
