Greetings,
So my 18? Cobia CC had a replacement under deck fuel tank (17 gallon) put in a couple of years ago. I just bought the boat a month ago so I?m trying to work out some of the bugs. I?m having trouble getting a full tank of gas in the boat. I ran it dry a couple of nights ago and I was only able to get in about 11 gallons before the fill tube would be filled up and not allow me to put more gas in the tank. The fill tube just fills up with gas and overflows over the top. The fill tube extends down approx 4? or so into the tank. I?m wondering if when the gas gets above the bottom of the fill tube if that would be enough pressure to stop gas from going above it. I was thinking of taking the fill tube out (held in by 3 screws and a gasket and cutting off the bottom 3? or so to make it close to flush with the top of the tank. Does this sound like a good idea and would there be any side effect to doing so? I?ve checked the vent hose and it is not clogged (hence a mouthful of midgrade ? nasty!).
A buddy said that because the filler tube is located at the rear of the tank that I might have to level off the boat to fill it up properly ? meaning that the boat is tilted up and the gas all levels out in the back of the tank? I guess I could put a level on the boat and see if that is true. What do you think? Thanks for the help.
Mike
