Direct Injection Fuel Rail: Installation

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

    1. Install the Teflon® Seal Guide onto the fuel injector tip.Use Special Service Tool: 310-207 Installer, Fuel Injector Seal Assembly.
    2. NOTE: Once the Teflon® seal is installed on the Teflon® Seal Guide, it should immediately be installed onto the fuel injector to avoid excessive expansion of the Teflon® seal.
      NOTE: Make sure that new lower fuel injector Teflon® seals are installed.

      Install the new Teflon® seals onto the Teflon® Seal Guide, using the Pusher Tool, slide the Teflon® seals along the Teflon® Seal Guide.

    3. Using the Pusher Tool, slide the Teflon® seals off of the Teflon® Seal Guide and into the groove on the fuel injectors.Use Special Service Tool: 310-207 Installer, Fuel Injector Seal Assembly.
    4. Remove the special tools.

  2. NOTE: Make sure the Teflon® seal is fully seated in the groove on the fuel injector before sizing the Teflon® seal.

    1. Massage and warm the Teflon® seal with your fingers before the Teflon® seal sizer tool is installed. This will aid in installing the Teflon® seal sizer tool.
    2. NOTE: The beveled opening of the Teflon® seal sizer tool goes away from the seal.

      Position the Teflon® seal sizer tool with the larger opening towards the Teflon® seal. Push while turning the Teflon® seal sizer tool 180 degrees.Use Special Service Tool: 303-1567 Sizer, Teflon Seal.

    3. Once the Teflon® seal sizer tool is installed, check and make sure the Teflon® seal is in the sizing portion of the Teflon® seal sizer tool.
