Installation Procedure


Object Number: 21855  Size: SH

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.

  1. Apply a few drops of clean engine oil to the male fuel 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. Once installed, pull on both sides of the quick-connect fitting in order to make sure the connection is secure.
