    Caution: The fuel rail stop bracket must be installed onto the engine assembly. The stop bracket serves as a protective shield for the fuel rail in the event of a vehicle frontal crash. If the fuel rail stop bracket is not installed and the vehicle is involved in a frontal crash, fuel could be sprayed possibly causing a fire and personal injury from burns.

  3. Remove the fuel rail bolts.
  4. Important: Do not separate the fuel injectors from the fuel rail unless component service is required.

    Use cleanliness and care when handling the fuel system components.

    Do not allow dirt or debris to enter the fuel injectors or fuel rail components, cap ends as necessary.

  5. Remove the fuel rail, with injectors, lifting evenly from both sides of the fuel rail until all the injectors have left their bores.
