I am going to try Permatex Liquid Metal Filler and seal from the outside.

If you can identify the holes, somebody (I forget who) makes an epoxy putty that is intended to plug holes in gas tanks. The kind I used came in strips of putty that you kneaded together and pushed into the holes.
I used it on a Farmall B gas tank 25 or so years ago and that tank has had gasoline in it constantly ever since with no leaks. I also coated the inside of the tank to prevent any rust breaking loose and getting into the carburetor.
It's not hard to do on a small tank, yet can save all manner of headaches later.
