Soldering EV tank

[drdwb]

So appears like Mr. Wayne had the right approach at least it worked in this case.
Been dealing with leaking EV fuel tank most of this spring, there were a couple hair line cracks in fatigued stamped underside. I tried epoxy which had worked on the other side, it’s still holding after 7-8 years, but didn’t here, perhaps bigger cracks. I tried 3 coats of SealAll as recommended, no luck. So I tried Solder, better but still not leak free, so for my last attempt from the outside, I had some copper foil taped (used for stain glass windows ) covered the holes and cracks, lots of flux and new solder. So far it’s held.
