Can you look on the manufactures label and see how thick the aluminum was when the tank was made.

the tank label was dissolved from gas . it appears pretty thick to me

Id guess about 1/8"

yes, around 1/8..

thats what i was thinkin

was that the top of the tank? If so specifically where?

bottom , about 2 feet from the back . the filler hose also had a crack in it where it goes between floor and the hull .

What is this going to cost. Next tank go 3/16.

tank is $766 with all connections and epoxy coated . plus shipping $250 . from NJ to MS that dont seem too bad to me . most other forums i read about this people said a grand just for the tank .

Did you ask Pat what he could do for you maybe a better price.
Must have had water under the tank no drain? Lucky you found it before it found you.
