[38 coupe]

You should be able to get your fuel tank cleaned out and sealed at a radiator shop. If your tank is really shot you can purchase a reproduction tank. Be aware that the fuel tank installs on top of the frame, below the body. It can get interesting to remove a fuel tank on a 35-40 Ford.

When you rebuild your carburetor, buy the little vat that the better parts places sell. It makes a big difference on how clean you get the carburetor parts. Don't vat the float.
