INSTALLATION PROCEDURE
1. Apply a few drops of clean engine oil to the male connection end.
CAUTION: In order to reduce the risk of fire and personal injury, before connecting fuel pipe fittings, always apply a few drops of clean
engine oil to the male pipe ends.
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.
2. Push both sides of the fitting together in order to snap the retaining tabs into place.
