My gas tank must have a leak. I don't see any wet fuel but when you open the hatch over the tank the smell is really strong. I pressurized the tank and put soapy water on all the fittings on top. No bubbles showed up so I cut the carpet and took out the cross member. I still don't see any wet fuel but the smell is overwhelming. My next step is to drain the tank and pull it out. Will it come out with the livewell in? Is there anything else I should check before pulling it? I think I'd like to go with a smaller tank. Is there one that I could get that would allow me to use the same cut out for the fill port?
UPDATE:The tank seems to be holding pressure. I'm not sure how many PSI I have on the tank but it's bulging out on the top a bit and stays that way. I'll leave it for a couple of days and see if it holds.
Pressure washed the tank and everything in that compartment. The hull and the tank were both really dirty. Covered in a black and looked like a greasy old tractor. I put a bunch of water in the hull and a good amount of dawn then took it for a drive, then drained it when I got home. I wonder if once upon a time there was a leak, and the fuel got it the hull. Do you think you'd smell it after a year? The boats always smelled like gas in that compartment and there is (was) some white sealer on the outlet fitting. Looked like somebody may have fixed (or tried to fix) a leak there once but like I said there's no bubbles in the dawn water there.
I'm wondering that after all this cleaning the smell might go away. That's going to be a few days to test due to it being soaking wet. I'll give it a day or so to dry and put it back in the garage to see. Right now it's hanging over the hill draining. I hope it's fixed. It needed new carpet anyway.
I'm going to remove the fitting and the hose where it goes through the aluminum to feed the engine and get it out where I can see the bottom of that fitting. It could be leaking there but it's not wet and like I said it's holding pressure.
NEWEST UPDATE: took the tank out. It was really dirty. almost greasy on the sides I couldn't get to before. Pressure washed and covered in water/dawn mix. Added about 10 PSI shop air. No leaks found. Pressure washed hull. Again it was really greasy. Cleaned all with dawn. I'm at a loss. All I can do now is wait for it to dry out and put it back together. I'm going to change all the fuel lines while I'm there. I'm kind of glad the tank isn't leaking but I never found the source of the smell unless it was all the greasy stuff. Thoughts anyone?
