Have Boat Questions? Ask a Boat Repair Expert.
Hi my name is Mike, I can help you with your fuel tank issue if you can clarify a couple of things for me...
You accidentally filled the "vent" line to the fuel tank? with fuel or water?
Did you overfill the tank and it came out the vent?
And by "fuel limit vent valve" are you referring the anti-siphon valve on the fuel pick up line or a one-way valve inside of the vent line? I'm not sure what kind of boat you have but fuel tanks vents are typically located on the side of the boat high above the water line.
Let's start by answering these questions so I have a better understanding of the situation and provide you with the best solution.
