Re: Apple juice tank
if it's already threaded, teflon tape should be enough to seal it. you could also try a copper or aluminum "crush washer" like cars have on the oil plug. if it's dry and clean, JB weld will work, too. i had to seal one of my studs on the crappy peanut tank, and it hasn't leaked yet.
is that the tank from the coleman dual fuel three burner? i was just looking at those the other day for my goodyear. let me know how it works.
