Topic: Cracked gas tank

[samIam]

I put the tank through Electrolysis and got real good results but have came up with a hairline crack the barely seeps gas.  Not even enough to drip.  I was wondering what other people would do in this situation.  I searched and saw that some have used JB weld but I used that on my stand pipes with bad results.  Maybe this would be different because the JB weld wouldnt be sitting in a pool of gas?  Here is a pic, kinda blury but easy to see.  Thanks in advance.

I once used JB Weld on a hole that had burned into my plastic dirt bike gas tank.  Held up great for years.  There are probably better solutions though

As much as I hate to recomend a tank sealer it might be your best bet for a leak stop, it's what I'd most likely do if I had a leaky tank after removing rust. If it wasn't leaking I'd avoid a liner but you gotta seal it somehow.

+1 tank sealer -

I had good luck with Caswell's epoxy sealer, the motorcycle dragons blood red version so you can see your coverage http://www.caswellplating.com/restoration-aids/epoxy-gas-tank-sealer/dragons-blood-gas-tank-sealer.html.

Caswell recommends applying it in two parts (half the cans on each application) - in my experience it works best to mix the entire batch and spend some "quality" time with your tank rolling it around and around and around until it begins to set. Use a flashlight to periodically check it and ensure you're getting full coverage. It should seal that right up.
