tank dent leaks around gas cap.. how to fix?
I have a tank that's dented in that feels awesome, but it leaks gas when in a tall wheelie. I tried ultra black gasket maker but only worked a few days. Has anyone tried JB Weld or any apoxys? I got a threaded cap so I don't mind perminantly attaching it as long as it don't leak any more.

JB weld breaks down in fuel, it'll quit working in a few months
you need something that isn't hurt by fuel.. It has to be safe for sealing fuel tanks. And when you do find an epoxy that is fuel safe, you must clean the area very good so there is no fuel residue.. If you get any fuel on an epoxy before it drys, it will most likely ruin it

discount auto sells an epoxy in a tube , its a small round tube that the epoxy in it is gray . its made to fix gas tanks and works good . also liquid metal works good (not jb weld) but liquid metal .

Dude ive got the same prob...around my cap theres a seam thats coming apart and ive used a gas tank sealer that you can get at a auto parts store however, when theres any pressure on it (like if i sit on it) the seam breaks and that stuff just comes apart. really sucks the only real way to fix it is welding it. if the hole isnt to bad try that stuff though first, its hard to find someone that is willing to weld a gas tank

it's really not that bad welding a gas tank, if someone is REALLY worried about it, give it an acid bath at a radaitor shop
I spent $50 to have my gas tank put in a acid bath, and brazed shut in 2 places at a local radiator shop
Recently my tank split open again, except this time imma just clean the inside out with some water and degreaser, dry it out, and weld it for free

if the gas is just leaking out from under the base of the cap then just get some gasket paper and make a gasket but make sure the vent on the base is working , on vortex gas caps i suggest taking the set screw out for the vent ..
if the tank it self is cracked then flush it out with water and weld it ..

Yeah mines leaking between the gas cap base and the tank. its got a rubber gaskit about 2mm thick maybe, and is held down by 3 screws to the tank. The cap base is aluminum and the tank steel so I can't weld it.. Thanks for all the info!

But I didn't drain the fuel, or clean the surface.. So that was probably my problem

on vortex style caps there is usually a little set screw that holds a check ball and a spring [right side of picture] and they usually dont work very well just take out the set screw and remove the spring and check ball and leave the set screw out ..
