Installation Procedure

Caution: In order to Reduce the Risk of Fire and Personal Injury: Before connecting the fuel pipe quick-connect fitting, always apply a few drops of clean engine oil to the male fuel pipe end. This will ensure proper reconnection and prevent a possible fuel leak (During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.)





1. Apply a few drops of clean oil to the male pipe end.





2. Push both sides of the quick-connect fitting together in order to cause the retaining tabs/fingers to snap into place.





3. Pull on both sides of the quick connect fitting in order to make sure the connection is secure.
