Good plan.

I was wondering. Instead of a fuel “tank” I was wondering about a
collapsible rubber fuel bladder like what’s used on some aircraft? I’m
thinking there wouldn’t be room for air and condensation, would there be?

I am not sure you can put a bladder like that under cover in an
enclosed space.
If he determines that the tank is compromised and he has access, I
would just buy a new tank. The plastic ones really seem to work fine
as long as they are ethanol compatible, and most are.
Then corrosion is not an issue. They make them in lots of sizes and
shapes. When I was rebuilding my boat (1989) I found the tank I wanted
and made a fiberglass console to cover it.

Bill may have fewer options since he is working with an existing
compartment.

You’re right about the plastic tanks. I have a tin bilge tank in my boat
but also have an extra 12 gal Mohler red plastic tank I’m adding for a
reserve. Mohler makes good stuff but like any of that type plastic, I
wouldn’t let it stay exposed to the sunlight for long periods (like all
summer) because the dry out and obviously turn orange and get brittle.


My tank is under the deck, not exposed to sun. A bladder would probably
work. But if it lasts 15 years, probably cheaper to get a new aluminum
tank and maybe out a rubber pad between the floor and tank.
