Economical general-purpose fitting
sealant. Outperforms tapes and pipe dopes. Seals and resists pressure in
air, oil, diesel fuel and hydraulic systems. Remains pliable at higher
and lower temperatures. Temperature range -65°F to 300°F (-54°C to
149°C); resists common shop fluids.
Blue Monster, like Chris said. Or, go to the Cat, John Deere, any equipment dealer, really, get a tub of pipe dope. Personally, I don't use anything Permatex. Had too much trouble with it. I use Rectorseal pipe dope with PTFE. It's pretty much good with any substance to 20k psi or some such. And we use a LOT of it.
Years back, I was putting in some outside faucets with polyethylene pipe. I've put in hundreds of feet of the stuff in my time. Anyway, there was one barb fitting that just would NOT seal - which happens once in a while. Putting a second hose clamp on it, the usual fix, didn't work either. I took it apart, inspected the fitting. Could NOT see anything wrong with it. So I re-cut the pipe and tried again. No joy. So I said "eff it", glopped it with Permatex, put one clamp on it and no more leak!

I've actually pulled the tank off. Gonna get as much of the rust flake out as i can.
It's driving the old woman crazy. Everyone i buy something new, i have to tear it apart.
Put some big rocks in the tank and shake it around. It'll help knock the rust off.
About once a year I siphon a lot of rust out of the tank on my 8N. I move the siphon hose around to pick up as much as i can. I filter the gas coming out and filter it again when i put it back in the tractor. I should do it more often
I wonder if anyone would actually buy polymer or aluminum replacement tanks for long life vehicles???
To answer your question with a question, what are the fuel cells on race cars made of?
I don't know. Likely some sort of expensive composit to resist puncture and fire. I think modern cars have polymer tanks, and the trucks I drive at work have aluminum. Cuts down on the rust.

And lo, on the 8th day, He commanded that the caliber shall be .45 ACP, and he saw that it was good.
And on the 9th day, He commanded that Massey Ferguson 135 tractors shall have fuel tanks not made of polymer, nor of aluminum, but that the correct tank shall be made of steel.

It's an esthetics issue. Very understandable.
