NOTE: Pull out the fuel rail in the direction of the fuel injector axis or damage may occur to the fuel injectors.

NOTE: Use compressed air to remove any dirt or foreign material from the cylinder head, the block and the general surrounding area of the fuel rail and the fuel injectors.

NOTE: When removing the fuel rails, the fuel injectors may remain in the cylinder head and require the use of a Fuel Injector Remover tool to extract. Wiggling the fuel injector by hand to break it loose may allow the fuel injector to be removed by hand.

NOTE: Should any of the fuel injectors remain in the head, then the fuel injector electrical connectors will need to be disconnected as the fuel rail is being removed.

Disconnect the fuel injector main wire harness electrical connector, remove the fuel rail bolts, then remove the fuel rail.
