I have heard that some guys have actually slowly melted the tank where it is leaking.
Drain all the fuel, rinse with water to get any fumes out, and use either a low voltage solder gun, or use a solder iron, but these get very hot.
Slowly run the tip of the solder gun over the leak area until it melts together.
One of my older cars had the tank leaking real bad, I was in the same position, no new tanks could be located. This tank is for a much larger scale, so I had more room to work with, so I removed the tank, scuffed it with 80 grit sand paper, and used a 2 part epoxy glue to seal it back up. So far, after almost 2 years, the tank has not leaked after the repair.May not be the best looking tank, but after I sanded the epoxy smooth after it dried, it is sure better than it was before.
