WARNING: This page is about a different car, the 2006 Chrysler Crossfire. However, it is still accessible from the selected car via links, so may be relevant.
The Fuel Rail is used to mount the Fuel Injectors to the engine and is itself mounted to the Intake Manifold. The Fuel Rail supplies the necessary fuel to each individual Fuel Injector and is located above the Intake Manifold and Fuel Injectors. The Fuel Rail is also equipped with a service port. The service port is used to connect a mechanical fuel pressure gauge to perform pressure tests.
