    Silver solder - just make sure the tank is completely empty of pertol fumes before you start wafting a torch anywhere near it.

      Braze the hole closed. You could also try tank sealer, but that's a less reliable method.

        I had the same problem, fortunately they holes were underneath, out of sight. I drained the tank down, sanded the area around each hole to bare metal then put on a layer of jb weld epoxy and let it sit for a day or two(tank open so it could cure from both sides) and that seems to have done the trick.

          If you have One pin hole, you likely have more.
          Check over the tank carfeuly, inch by inch, look for paint bubbles or blisters.
