Although this is not about a Model T, it could happen to a T as well. The gas tank on my 1941 Chrysler was coated many years ago with one on the first gas tank sealers that was not resistant to ethanol. Now I want to clean out the old coating and reseal with the new stuff. Any ideas if there is a solvent that will dissolve the old coating?

Might try methyl ethyl ketone it was used as a thinner on some of the coatings and will probably cut it loose. KGB

The sure way is to cut the tank open on three sides and open it up like a sardine can.
Sandblast the inside and fold it back together and solder the places where it was cut open.
After a leak test you can seal it with the new sealer
A better way is to tin the inside of the tank when it is open. Then you won't need to use sealer.
To have that done at a radiator shop will cost more than a new tank, if one is available.

New tanks are widely available for that car. Might be the better way to go. I bought a new tank for my 49 Plymouth from Kanter.

I just cleaned 2 tanks with 30 year old sealer last week. I used a gallon of lacquer thinner. Soaking and turning dissolves some of it into a syrupy fluid which I strain through coffee filters for reuse. What remains in the tank sort of sets up and I can re-seal it with the Ethanol/alcohol proof sealer. I have had to re-seal 3 tanks over the last several years this way and have had good results from this process. I'm sure there are better methods but this has worked for me.

I really appreciate all the responses! I did find new tank from Kanter for 300.00. My tank is in very good shape otherwise, so I will try to clean it up first using your suggestions. Although I will try to stay away from MEK as per Jack. Could let my buddy Keith try it; his liver is probably shot already:-)

I may be having a little brain slippage here, but years ago couldn't you get a tank "beaded"? I seem to recall that you could take a tank that needed cleaning to a shop and they'd put some beads (probably pea gravel) in it then put it on a machine that would spin it for a long time, sort of like a rock polisher. It would cleaning it to new condition inside.

I never had this done, but it seems to me that some guys I knew did....

I think I would spring for a new tank.
