Stripped Gas Tank Threads Options

[cary]

Working on replumbing my new fuel pump. So I decided to loosen the nuts that cinch down the fuel tank output pipes. Big one came off without a hitch. The return line, that's another story. The aluminum nut totally stripped out. Steel bung threads are embedded with aluminum.

Has anyone bought the M18 * 1.0 die or thread restorer and cleaned those threads before? Kind of an odd sized thread.
Hate to give up on this tank.

Had I little trouble at hose shop. They don't really deal in the small stuff. But we finally found what I was looking for.



With my bunged up threads they were tough to get started and not go on cross
threaded. But you can see them sitting here with 2 gallons of gas checking for leaks.
Dry as a bone. But I am going to mark the bottom of the tank .... never remove bad threads

I tested one of them on one of my other tanks. They went on smooth as silk. Nice product.
Note : They seal with an O-ring.

I'd say for cleaning the threads if the tank sealer is your only issue. Clean threads with the nut with the cuts in it. Oil as you go thru the cuts. I turn a 1/4, back up a 1/2. Rinse and repeat until you get to the bottom. I took it off once and cleaned the threads with a wire brush. Then use a new unused nut to tidy up the starter threads.
