  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. 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. Use Special Service Tool: 303-1567 Sizer, Teflon Seal.
    4. After one minute, turn the Teflon® seal sizer tool back 180 degrees and remove. Use Special Service Tool: 303-1567 Sizer, Teflon Seal.
