So my aluminum fuel tank is suffering from the good old methanol blues. I had it made when I was in Florida and the corrosion started there. Back here in Colorado it's not so bad, but still enough that I'm going to swap it out just to prevent issues in the future. I'm going to build a new one from stainless, but having trouble deciding on what thickness to use. I've measured .075, .063, and .050, and it seems the .050 is what I'm wanting. It's still decent enough thickness to hold up well, but not so thick that my tank will weight a million pounds.
What thickness would you use to build a tank if you were doing it? Keep in mind, it's triangular shaped, fits behind my seat, and holds approx 7 gallons.
