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

REMOVAL

WARNING:

The fuel system is under constant pressure even with engine off. Before servicing the fuel rail, fuel system pressure must be released.

Perform the fuel system pressure release procedure. Refer to FUEL SYSTEM PRESSURE RELEASE .
Remove the engine cover. Refer to COVER, ENGINE, REMOVAL AND INSTALLATION. .
CAUTION:
The left and right fuel rails are replaced as an assembly. Do not attempt to separate the fuel rail halves at the connector tube. Due to the design of the connector tube, it does not use any clamps. Never attempt to install a clamping device of any kind to the connector tube. When removing the fuel rail assembly for any reason, be careful not to bend or kink the connector tube.
Disconnect the PCV hose and position aside.
Disconnect the make up air hose and position aside.
Disconnect the wire harness connectors at all eight fuel injectors.

Apply a small amount of engine oil to each fuel injector O-ring. This will help during fuel rail installation. Take care not to cut or roll the fuel injector O-rings.
Using a side to side motion, gently rock the left fuel rail while pushing down until all four fuel injectors have completely seated into the machined holes of the intake manifold for each bank.
When connecting the wire harness connectors, verify the fuel injector connector is locked to the injector by lightly tugging on the connector.
Start the engine and check for leaks after procedure is complete.
