Gas tank problems
So, took the tank off my A, and cleaned all the varnish out with acetone. Some crud came with it. Looking down inside the tank, it appears to be in surprisingly good shape, no rust as far I can tell. However, the tank is leaking slightly around the threaded insert in the bottom of the tank, where the sediment bowl attaches. What would the best fix be?

Re: Gas tank problems
If it is leaking from the threads, I suggest removing the sediment bowl assembly, then cleaning it's threads and the ones in the tank, and then reinstalling using a good quality pipe thread dope. If you have a metal fuel line, you will need to have the line attached to the carb. before the final tightening of the sediment assembly so you can line up the fitting. Do NOT back it put to align the fuel line if it can be avoided.

Re: Gas tank problems
Thanks for the advice. No, it's not leaking through the threads themselves, but rather the seam between the tank body and the threaded part (which is spot welded to the tank). I thought about trying to seal it from the outside with solder or some such. Don't know if the threaded part is cast or machined, and I'm not 100% certain that its steel. Or, I would be tempted to try a fine MIG bead on a low power setting around the visible outside of the seam. The latter is probably not such a good idea, as it would get the part pretty dang hot.

Re: Gas tank problems
JB Weld adheres well to clean metal and is not gas soluble.

Re: Gas tank problems
I am not suggesting this as a solution ...just a bit a humor that falls in line with this. One day back when I was 16 and had my first car which was a 1972 Impala (What A tank!) I was going down the backroads to my grandpa's farm. I had to cross one of those old bridges where they simply had to big planks of timber laid across a bridge bed. I was a little off to one side and missed the planks. The back end of my car hit hard.....knocking a small hole in my gas tank...I almost ran out of gas before I got to the farm. I asked my grandpa what to do and he went back in the house and came out with a bar of Ivory soap. He rubbed the bar across the hole to fill it and Wha-La the leak stopped.....and being that I was a poor high school student...it stayed that way until I sold it 3 years later.. Grandpa also used Ivory soap for catfish bait. It is a very versatile product.

Re: Gas tank problems
To seal where the flange attaches to the tank, clean the paint off as well as possible then use JB Weld Stick, It is designed for that type of use.
