fixing a leaky tank?

[Jim mac]

not a rusty tank, this tank ive got leaks where the tank hooks to the rubber cushion. maybe it got bumped or rocked real hard and the U channel is leaking behind the spot weld. I can't see the leak, anything I could sweat into the gab between the tank metal and the U shape bracket? jim

I have no experience with this, but maybe solder?

Maybe silver solder or braze. Or fill with water and TIG from the outside. Thats probably the easiest honestly. Post pics

Those cups that hold the rubber grommet are spot welded, I bet the leak is a spot weld that tore. Braze or soder all the way around the cup. That should do it.

This product is great. The glass jar has a cotton ball applicator. This will seal holes and stop your leaky gas tank. I have an 86 200x tank that leaked around the exact area you described and it worked perfect. You can top coat this stuff as well

I would try a low melting point solder.

I have tried brazing cracks in tanks and it seemed like oxy/acetylene just brought out more issues....

I have grown to really like soft solder. Sand or wire brush to get bright shiny steel, use acid flux, and a high watt soldering iron. Sometimes the soldering iron doesn't have quite enough heat, so it is "helped" with a propane torch- heat the end of the soldering iron with the torch for a boost of heat. I have closed a 1/4" rust hole with a blob of solder. Using the iron, as opposed to direct flame from a torch seems safer- don't blow yourself up!!
