Mix and apply to clean dry areas. For sealing of intergal aircraft fuel tanks. Best if applied to seams during assembly but I have used in in situations like described. I had the same issues with my 31 Coupe and purchased the later steering support from Berts that eliminates the load on the fuel tank. My leak has stopped for now.

I have to thank you for this suggestion! I got the stuff and it's great. Like you said, it adheres like crazy, and it's a flexible rubber membrane. A little sloppy putting on, but I think this will do the trick for some time to come.
