Fuel Line Coupler: Service and Repair

CAUTION:
^ Place a dry chemical (Class B) fire extinguisher near work area before attempting any On-Vehicle Service.
^ Always apply a few drops of clean engine oil to the male pipe ends before connecting fuel pipe fittings in order to reduce the risk of fire and personal injury. 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.
^ Wear safety glasses when using compressed air in order to prevent eye injury.
