Fuel Supply System

The fuel rail and connecting pipes after the high pressure pump, are under extremely high pressure! When working on engine or fuel injection system, fuel pressure must be relieved to residual pressure before opening high pressure components. Never attempt to open a fuel connection with the engine running. Refer to the service information for the proper procedure.

For all fuel supply system component locations, removal/installation procedures and tightening specifications, refer to the service information.
