Tank liner and leak?

[numus]

I had the gs500 sitting for a couple weeks (had seafoam in the gas tank) and recently I was going to start working on it and notice the gas tank is empty and it smells like gasoline outside the bike. Any idea where it may be leaking from?
Also there is horrible rust in the tank (had a rust leak that i sealed with jbweld a few months ago). Do I have to remove the tube inside the gas tank before I put a new liner in it?

You have a tube in the tank ? Anat sorta tube - you're not talking about taht little metal tube are you - that guy ignore it.

JB weld doesn't work ... you need to weld the bugger.

In your case depending on how and where the leak is, I'd recomend an acid treat and clean and oil - to stop flash rust, you can use the hole you got to help dry the tank ... then weld it up.
Then you do a clean and dry without any acid really, just repeat hot water 5-6 times and then acetone. Then you can kreem it.
Or you could treat it with POR15 blue stuff after welding - and remember in a rust free tank you need to use very little of it and it gives off a grey powder ... then rinse with water, dry it as much as possible and POR15 it.
The reason you want to acid treat it before welding ... you could well have 5-6 spots you have to weld up ... not just 1.

Cool.

JB Weld claimed it was Gasoline imperiable and specifically that it can be used on gas tanks Already treated the majority of the bottom of the tank with it cause no one would wield the tank after it has been used in town

Oh well.. The tube i met is the res/on (idk what it is called but we use to call them snorkels for other uses). That goes into the tank and is held in by 2 screws.. I am unable to get those 2 screws out (rusted in place?)

Dude jb weld will not stand to gas ... or even if it did, it wont when the underlying metal rusts away.
I think you need to find a welder ... a burning tank aint no problem, cos you are dealing wiht welding it anyway, so it has to be painted.
Run 3-4 gallons of very hot water through it a few times and it will be gas free ...
Or atleast free enough to stick a match in from a few feet and have it all "poof" itself out.

I'd do hot water, acid and more hot water and then weld it. Not weld it right in the begining. Acid will tear off the iffy parts and leave you with more holes to weld, but once welded it will be good.

I'll have a stab... it's leaking from a hole somewhere either in the tank or fuel line coming from the tank or the petcock 

Hope that helps.
