Important: Relieve the fuel system pressure before servicing any fuel system connection. Refer to the Fuel Pressure Relief .
Caution: Wear safety glasses when using compressed air in order to prevent eye injury.
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.
