I have been talking to boat owners at our club about these decades old
aluminum fuel tanks many of us C&C'ers have.....a few have had the tanks
leak (or weep) as they call it. The leak(s) were not caused by the
bottom(s) rusting (as aluminum does not rust, it corrodes) ......the
leaks were caused by stress cracks in the weld joints.
Two members took their tanks out for examination and found the leaks in
the weld joint(s)....took the tank(s) to a metal fabrication shop and
had them repaired......actually had the weld joints reinforced and put
the tanks back in. One member did it 10 years ago and the tank is still
in his boat with no problems.
I am leaning now in this direction.....probably won't save me any money
but that is not as important as getting a new tank installed with
potentially new fittings, adapters, elbows, etc, etc. Getting a fuel
tank in and out of the engine compartment is not like working on the
'work bench'.
