Fuel Rail

WARNING: This page is about a different variant/trim than selected.
FUEL RAIL

Refer to COMPONENT INDEX .

The fuel rail supplies the necessary fuel to each individual fuel injector. 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. The fuel rail is a composite design. The four fuel rail fasteners thread directly into the composite intake manifold and are a self-tapping design. The intake manifold can be serviced without removing the fuel injector rail. The fuel rail and fuel injectors must be installed into the intake manifold as an assembly. Do not attempt to install the fuel rail when the injectors are in the manifold. Always install new O-rings on the fuel injectors. 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.
