Leaking Gas Tank?

[mbo_1971]

Hey guys - long time since i have checked in. Lots of cool projects going on. I am having an issue that I can not seem to figure out. I think I have a leaking tank. What is weird is that when conditions are dry, there are no signs of a leak (no sheening in the bilge or bad fuel odor). However if I get a bunch of water in the bilge, i get sheening and bad fuel odor. What gives? The boat is an '84 and the tank is original. Im thinking it is shot (nice fall project), but just dont understand why it would be apparent when wet and not dry. I have checked the sender gasket and the fill hoses and they all appear to be fine, so I am thinking it is a busted weld. Thanks for any thoughts you might be able to provide.

If it is a tank, who are we recommending for tanks these days?

I used Sunshine Marine Tanks. Great service, great work and very timely.

Not sure on how it appears to be showing the leak when water is in the bilge only. Possible it is puddling in front of a cross member and only when extra fluid is in there does it get over and back to the transom. If you have a tub for the tank like my boat has (85 18'SF) then maybe the tub has to fill to the height of the holes for the fuel line to allow the leaked fuel to run to the transom. Just not sure what your boats has for a set up as I have never had one of those.
