Tank Restoration

[Rabbid]

So I just got my tank today wasnt really sure what to expect with it. Over all its not in terrible condition but it does need some love. It has two petcock threads but one was filled in with what appears to be brass. Minor rusting inside with only a couple visible pinholes.

1. What would be my best route to unplug the second petcock thread. I thought about drilling out as much of it as I could and see if I could retap it.

2. A bike shop in town told me that after cleaning up the inside to just use a sealer and it will take care of the pinholes. How effective would that be?

Its be brazed. brazing is like soldering, no base metal has been melted. Therefore, all that has to be done is for it to be heated up and melt the brazing off. Of course some clean up and retapping is needed.

So whats the most effective option heat it and try and melt it out then tap it or just drill and tap.

You only need one petcock.

Maybe I'm too cautious but If i had to use the tank I'd like to see the rust holes brazed shut.

The tank sits low on the frame(high tunnel). If I only use one fuel will get stuck on half the tank. It looks like its sitting high on the frame in that picture but it actually sits lower in the front
