Installation

1. NOTICE: 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. NOTICE: 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.
      

1. 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.
