Re-epoxied the tank seam yesterday. It wasn't leaking exactly, just weeping very slowly (not enough to actually drip on the ground). I tried to be careful to get a thick layer on the leaky spot despite the action of gravity working against me. It helped to let the epoxy thicken for a couple of minutes in the mixing cup before starting to apply it.

Seems it is getting under control and the dealer should get you a new tank.

Do you have any picture of the location of the leak ?  Or can you get one ?

I did take pictures.

Just checked the epoxy, which cured overnight. A pinhole formed, through which gas is still seeping!

Going to apply again today, and after the epoxy is hard (but not fully cured), I'm going to turn the tank right side up (but keep it tilted to keep fuel off the repaired area), and release my fuel cap overnight so that any vapor that builds up is released from that side. I did this on the first application but not the second, and I'm guessing that was why the epoxy weakened during curing.

Just to circle back: the second coat of JB Weld epoxy fixed my leak. I was extra-generous with the epoxy this time, because the area of leakage is on the underside and not visible without taking the tank off. So I'm unlikely to get any further leaks along that weld seam.

As best I can tell, this is a permanent fix. If it's still holding a week from now, I won't bother to try to get the tank replaced under warranty. (The devil you know...)

On the other hand, Rich, according to Kevin Mahoney:

Quote
Somewhere along the line RE changed the stamping for the underside of the tank to allow for a little more room and to make a better tank. The net result is that the flanges are wider on new tanks.

Which means, a) a replacement may be a better choice for the long run, and b) a replacement won't fit the same, and you'll have to adapt it with spacers (which I did).

Just saying...

  DON'T  rely on Jb weld, on the underside of your tank as a permanent repair....  If you don't want to get a warranty tank. Take it to a radiator shop. They can weld or braze it for a permanent repair.  They can also flush out the old tank sealant... which will be damaged from the heat... and reline it with Red Kote.

       Rich,

           Why can't you remove your tank, ship it to your dealer UPS or FED-X, let the dealer evaluate the leak & ship you a new & improved tank on warranty?
(Am I correct your dealer is far away?)

           Kevin Mahoney is aware of your story through this forum & should back you up with your dealer.

           J-B Weld is good (I love it) but will come loose sooner or later exactly when you don't want it to.

           Maybe I'm unaware of something that makes this not viable. In that case, just ignore me. Everyone else does  :)

This talk about fuel tank coatings has me curious .is it a rust inhibitor or a sealant primarily? And does anyone know what the self sealing stuff the Air Force used in the days on bullets and dogfights was? I believe it was developed by the poms to help their bombers get home just curious . And it makes me wonder.

It's mostly for sealing but does also help prevent corrosion.  It's critical with all of them that the interior surface be cleaned and prepped right.

I haven't seen any self healing types available in the civilian market.

Neither have I. I wonder if it would be feasible ? Would certainly add real meaning to the term " bullet proof" though.
