    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 connection end.
