Fuel Rail and Injectors Installation F Car


    Object Number: 222050 Size: SH

    Important: DO NOT reuse fuel injector O-ring seals. Install NEW fuel injector O-ring seals during assembly.

  1. Lubricate the NEW fuel injector O-ring seals with clean engine oil.
  2. Install the O-ring seals onto the fuel injectors.
  3. Install the fuel rail, with fuel injectors, into the intake manifold.

    4. Press evenly on both sides of the fuel rail until all of the injectors are seated in their bores.

  4. Apply a 5 mm (0.2 in) band of threadlock GM P/N 12345382 or equivalent to the threads of the fuel rail bolts. Refer to Sealers, Adhesives, and Lubricants .

    5. 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.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  5. Install the fuel rail bolts.

    6. Tighten
    Tighten the fuel rail bolts to 10 N·m (89 lb in).
