WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  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.
    NOTE: The beveled opening of the Teflon® seal sizer tool goes away from the seal.
    NOTE: Do not use the injector without re-forming the Teflon seal after replacing.

    1. Use a soft brush to clean the inside of the re-forming tool before each use.
    2. 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.
    3. 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.

    4. 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.
    5. After one minute, turn the Teflon® seal sizer tool back 180 degrees and remove.

  3. NOTE: Take care to prevent foreign substances from adhering to the O-ring or the seal surface.
    NOTE: Take care to prevent foreign substances from entering the fuel injector inlet.
    NOTE: Make sure that new fuel injector support rings and new fuel injector O-ring seals are installed.

    1. NOTE: The new the fuel injector support rings must be installed in the correct orientation with the wide surface area facing up against the fuel injector O-ring seals. Improperly installed support rings may cause the fuel system to leak.

      Install the new the fuel injector support rings.

    2. Install the new fuel injector O-ring seals.
    3. Install the new the fuel injector clips.
