How is water getting in but gas is not getting out? My tank is sealed. There should be gaskets where the sending unit is. The sending unit should be sealed. The gas filler tube should have clamps on it to seal it. The vent tubing should be peaked to keep water from flowing up hill to enter the tank. I would not put a check valve in the fuel line but I would make sure that my vent line was higher in one spot then my vent to keep water from being able to flow down hill to my gas tank.The screw in gas cap on the hull should have a gasket. How are you getting enough water in a tank to be a problem?
