Re: Fuel tank longevity
We have a 1990 34 hull # 201 with the original aluminum tank. That would put it at 23 years old! Still visually appears to be in good condition. I think the main problem is boats that have bilge water in contact with aluminum especially if in a salt water environment. We keep our bilge bone dry. The tank is also elevated about 2" off the bottom of the bilge and no contact with the keel bolts. If I ever do have to replace I would go with the new factory provided molded fiberglass tanks.
