  10. Remove the fuel injectors from the fuel rail.
  11. Remove and discard the fuel injector clips.
  12. NOTICE: Use minimum force to remove fuel injectors that remain in the cylinder head with the Fuel Injector Remover tool, or damage to the fuel injector assembly may occur. Rocking the injector by hand to disconnect it may remove the injector manually.

    1. Using the special tools, remove all fuel injectors remaining in the cylinder head.

Installation

  1. Remove and discard the fuel injector O-rings. Remove and discard the fuel injector backup rings.
  2. NOTICE: Use care when removing the lower Teflon® seals to avoid scratching, nicking or gouging the fuel injectors.

    NOTICE: Do not attempt to cut the lower Teflon® seal without first pulling it away from the fuel injector, otherwise damage to the injector may occur.

    1. Pull the lower Teflon seal away from the injector.
    1. Carefully cut and discard the lower fuel injector Teflon seals.
  3. NOTICE: Do not lubricate the new lower Teflon® fuel injector seals.

    1. Install the mandrel onto the fuel injector tips.
      Use Special Service Tool: 310-207 Installer, Fuel Injector Seal Assembly.
    1. NOTICE: After installing the Teflon® seal on the Teflon® seal guide, install it on the fuel injector immediately to prevent excessive expansion of the Teflon® seal.

      Install the new Teflon® seals onto the mandrel, using the pusher to slide the Teflon® seals along the mandrel.
    1. Using the pusher, slide the Teflon® seals along the Teflon® seal guide and into the groove on the fuel injectors.
      Use Special Service Tool: 310-207 Installer, Fuel Injector Seal Assembly.
    1. Massage and warm the Teflon® seal with your fingers before installing the Teflon® seal sizing tool. This will help in installing the Teflon® seal sizing tool.
    1. Position the Teflon® seal sizing tool with the large opening facing the Teflon® seal. Press and turn the Teflon® seal sizing tool 180 degrees.
      Use special service tool: 303-1567 Teflon® Seal Sizer.
    1. After installing the Teflon® seal sizing tool, check and make sure the Teflon® seal is in the sizing portion of the Teflon® seal sizing tool.
    1. After one minute, rotate the Teflon® seal sizing tool back 180 degrees and remove the Teflon® seal sizing tool.
  4. NOTICE: Use fuel injector O-rings made of special fuel-resistant material. Use of standard O-rings may cause a fuel system leak. Do not reuse the O-rings.

    NOTICE: Do not lubricate the new lower Teflon® fuel injector seals.

    NOTICE: The new fuel injector support rings must be installed with the wide side facing toward the fuel injector sealing rings. Incorrectly installed support rings may cause fuel system leaks.
