Got the new gas tank in '51 Chevy completely assembled and in the truck with lines run. Put gas in it tonight and it is leaking around the brass nipple that screws into bottom of tank and goes through cab floor. I put the thread sealer on the nipple. I've seen some other threads that complained about the new gas tanks. Anyone have any thoughts/solutions? I was ready to crank up for the first time today, but don't think I want to try with leaking tank!

I told you that I too had the same problem. The new tanks have a design flaw. I never could get mine to seal up either, and I feel that as long as the repro. mfg. continue to make them with the current design at the bottom, there are always going to be problems. On the original Chevy tank, there is a round, flat plate on the outside of the tank, that the brass nipple screws into. This is what the nipple tightens up against, and makes a tight seal. On the new tanks, there is no plate on the bottom. Just a threaded hole. Like I said, I never could get mine to seal either. I ended up taking my new tank back to Chevy Duty, and got some muratic acid, and a clean amd seal kit from Eastwood, and reconditioned my old tank. That was last summer, and so far, no problems.

I did speak with one individual who indicated that I may can try welding the pipe nipple to the bottom of the tank. By placing the weld on the outside, it may keep the tank from leaking.
Anyone tried this approach?

just a thought...
