Can a gas tank be welded? The HFH's 50 year old tank has developed a leak on one of those ridges on the underside. It is dripping a bunch of drops per minute, so I am keeping the garage door open at night and an electric fan blowing the fumes out. I thought I read or saw something on TV about a "super adhesive" that can be applied over gas, but I migh be wrong. Or where can I get a gas tank? Bill Yes, a tank can be welded. Often times without blowing up. One guy in San Jose got away with it seceral times - the only problem was the last one. The question is, should it? A weakness at one place that causes a leak may soon be somewhere else, anyhow. Just about anything can be done, given expertise, money and material. As for me, I'd look for a good tank and get it cleaned and sealed, if needed. Karl > Can a gas tank be welded?

Jeff  SignaturePosted via a free Usenet account from http://www.teranews.com Or, if you can afford it, to a Gas Tank Renu franchisee. They use two different baked-on coatings; one for the outside and one for the inside. The outside looks like baked-on undercoat; the inside coating is different and guaranteed to be impervious to various modern gasolines. The whole thing is guaranteed for as long as you own your car. I had the tank done on our '56 Clipper hardtop about five years ago and am very pleased. Cost was $285, though.

The procedure recommended in my welding book is to flush the tank with water several times, then place the tank with the are to be welded facing up, and fill the tank with water as much as possible to reduce the free air space in the tank to the minimum to reduce the area that can hold fumes. Clearly, this is something that should be done by an expert. I once succesfully repaired a gas tank using polyester resin in a carrier (didn't have fiber glass on hand, used a paper towel soaked in resin. It didn't need a lot of strength, it just had to hold the resin). But if there are now products on the market specifically designed for this purpose, use one of them. > Can a gas tank be welded?

IIRC, your garage is part of your home. You and Ellen are much too important to take the risk. Then, either replace or repair the tank. You may get some gasoline resistant two part epoxy to contain things until you come up with a real fix for the problem. Cancel the leak............................. I put fuel in it yesterday, and I wondered why it would only take 3 gallons. You know the old saying "water seeks it own level"? Well so does gas. The filler neck is way higher than the sending unit. The fuel leak was out the TOP by the sending unit and it ran down under the tank. and was dripping, as in running around the tank and dripping from the bottom. I pulled the cover plate out of the trunk floor floor, and there right on top of the sending unit was wet gas, a whole bunch. Tomorrow (we have garage open) I will clean off the sendig unit top and find some fuel proof epoxy. Since I have had the car, that sending unit has always been a sore point. I think the PO, had had work done on the sending unit at some point and whoever worked on it could not tighten the screws all the way. There is no way to get a screw driver around to all the anchor points, plus you cannot find a 56J sending unit. Thanks BG >> Can a gas tank be welded?

It took maybe and hour to fix. Chip Signature-------------------- http://NewsReader.Com/ -------------------- Usenet Newsgroup Service $9.95/Month 30GB Until it is really fixed... Run it down to 1/4 then start looking for a gas station. Stop filling when you've put in ten gallons. That should do it for most driving conditions.

And put in some sealer from Bill Hirsch in Newark, NJ. And put POR 15 on the outside. Havn't had a leak in about 6 years or so . Why not R&R the sending unit, and use a new cork gasket coated with Permatex No. 2 and copper washers under all the screws? That should work just fine... nate > Cancel the leak............................. I put fuel in it yesterday, and > I wondered why it would only take 3 gallons.

As for the copper washers, ........ "I don't see no stinkin copper washers". What is so special about these washers? I like the idea of using the Permatex No. 2, but where do I get a gasket for a 56J?
