    NOTE:
    • Use care when servicing the fuel system components, especially the fuel injector electrical connectors, the fuel injector tips, and the injector O-rings. Plug the inlet and the outlet ports of the fuel rail in order to prevent contamination.
    • Do not use compressed air to clean the fuel rail assembly as this may damage the fuel rail components.
    • Do not immerse the fuel rail assembly in a solvent bath in order to prevent damage to the fuel rail assembly.
  1. Replace any damaged O-ring seals that were removed.
  2. Lubricate the O-ring seals with clean engine oil.
  3. Install the fuel rail assembly into the intake manifold. Tilt the fuel rail assembly slightly to install the injectors.
    4. NOTE: 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.
  4. Install the fuel rail bolts.

    Tighten:  Tighten the bolts to 10 N.m (89 lb in).

  5. Install the fuel injector electrical wiring harness to the fuel rail.
