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

      Install the NEW fuel injector O-rings and lubricate with clean engine oil.

    2. 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.

    3. Inspect the inlet stopper, if it is damaged or comes off then discard the inlet stopper. The inlet stopper is not needed for proper function. Ensure that any debris from the inlet stopper are removed. If the inlet stopper is intact and undamaged do not remove the inlet stopper from the fuel injector.
    4. The upper side of the support ring has the wide surface area.
    5. Fuel injector support ring.
