Yes my original post was about the merits or otherwise of soldering versus braising. Thats what I wanted to find out. What is the bracket made of? Will it take heating or even welding?

FYI: additional info.
1. Sometimes the leak is from the bracket coming loose and gas is leaking out from the holes under the bracket.
Bracket was riveted to tank with re-enforcing plate inside of tank and then the joint was soldered to stop leaks.
Cracks also sometimes appear in the tank between the bracket mounting holes.
2. In my Coupe there was a small crack (1/4 inch long) in the tank itself, located about 1/4 to 5/16ths inch away from the bracket. A brass patch was soldered over the crack and bracket was re-soldered from the outside.
I only say this because I was told at the time (20 years ago) that leaks come from under the bracket and that was not true in my case.
I installed the 1931 FACTORY installed engineering change brace which mounts to dash rail just below windshield and which replaces original bracket. This new bracket removes strain in gas tank and transfers strain to the dash rail. Also I removed the rubber "gasket" inside the original bracket and between steering column.

The whole inside was what they called Tern plated, to act as a sealer. The inside was basically bathed in molten tin/lead. The stuff doesn't last well since it oxidizes too. Modern fuels don't help that at all.

I have used several different marine epoxies on my vintage mahogany boat over the years. Total Boat and Jamestown Distributors have a good selection depending on the specific application.
I totally agree.

A place I used to work years ago had a dry ice box to blow CO2 in and make a small block of the stuff. When welding on an old helicopter tank we would just put dry ice inside here.
