Default Re: Fuel shut off valve

A grease is available for gasoline valves or any other moving part immersed in gasoline. It is called EZ Turn Lubricant, see link below. This will help seal the valve and prevent the slow leakage you describe. If the valve is severely worn it is best to replace it as it is difficult to lap the parts together to get a good seal. You do need to drain the tank.
