Re: Gas tank repair

On my old car projects, I used a combination of a couple of things for some tank problems.

My '67 F250 had an in-cab tank, that was removed and a under-bed tank added. It had sat for a decade when I got it and was full of crud. I drained it, then cleaned it with a POR15 cleaner...and discovered a couple of pin holes. Not bad. I used a putty-type gas tank patch on those, and then sealed the tank with the POR15 sealer. That's twenty years ago. An F-500 with in-cab tank got the same treatment, but had no leaks.

On a '66 Futura that my daughter had, there was a previous repair on the tank with improper patch; I used the same putty. That's 15 years ago. Same POR15 sealer.

I've used that same process on my '37 115C tank, two other Falcons and a Mustang. And a Ford 8N.

My '40 110 tank though, needed to be boiled out at a radiator shop; the crap inside wouldn't budge with any of the cleaners I tried. They put several holes in it, boiled/steam cleaned it, replaced the drain plug which tore out of the tank, then sealed it and coated the exterior. That was about $300 to have done.
