Leaky Gas Guage

JB Weld seem to contradict themselves in the answer to question #3. First they say "JB Weld is completely resistant to water, gasoline.....", then they say "For wet-surface or submerged water or gasoline repairs, try our Steel-Stik or WaterWeld."

those 2 products are for working patching under water or fuel...(working submerged) where air cant get to it to dry

if you use any flame to repair tank make sure you clean to properly prevent possibility of explosion!

Gas tank + flame...yeah...let me know how that works out for ya, I'll be the one standing waaaaay over there.

Before I try anything involving "flames" I would follow Andrews book and use a cork gasket with some gasoline proof sealer. If you use a quality cork gasket I believe it will not leak. I have follow this with great results and no leaks.Try this first.

You could try, after cleaning the rust, coating the threads, gaskets and sealing areas with Permatex Thread Sealer. We have been using it with modern gas on the GVA. Seems to hold up good. It's the white stuff in the small tube.

Here's one recommendation:

When after you have worked on, fixed, repaired or changed out your gas gauge, and you go to the filling station to "filler up", bring with you a five gallon gas can, a funnel, a length of hose, a screwdriver / wrench or whatever tool needed to disconnect your fuel line.
In my case I had to run into the store to buy these items while gas poured into my cab, I then drained my tank to below the gauge level, drove her home and made the proper repairs...which in my case meant chucking the Chinese nut in the trash and putting the original one back one, it was not "shiney and new" but damn if it doesn't work.
(Never throw original parts away)

Well, I'm happy to report that the repair is soldered and I'm not in a burn unit. I will admit that it was a bit stressful with the kaboom worry. I used a high watt electric solder iron so no open flame. I also did not want to make any sparks. It was more challenging than using JB Weld but gas will never soften solder. It's all back together now with cork gaskets with gas proof sealer and I hope to enjoy some fume free driving. Thank you all for your replies and suggestions.

The real test will come when you fill the tank above the gauge.
Sounds like you did a "bang up job" (pun intended)
