Need some help on a simple problem. The gas tank has 3 holes in it adout 3/16 of a inch wide and runs adout 5 to 8 inches long. The bad spot is right where the tank is bent to form around the back of the set. I can fix it but is it worth fixing, I don't want this to leak in time or have that gas smell in my truck. I think I have a tank from a 69 ford truck. It was also a step side truck so the tank was behind the seat to. Will this gas tank work. Just wanted some input before I dig it out.

 

When I had my gas tank cleaned and checked by my local radiator shop, he soldered on some brass? sheet metal patches where there were a collection of pinholes (under a strap.) You might be able to solder patches on your holes, but I'd have a professional do it - too risky to do at home. Mine only cost like $30 to clean, check and fix.

After cleaning and repair, give it a treatment with slushing compound. It will seal any pinholes or weeping seams and prevent further deterioration/ loose particles.

 

Got My Gas Tank Back Today From Having It Cleaned They Advised Against Coating In Side Said They Have Had Tanks That The Coating Had Turned Loose And Had Bigger Mess Than With Rust What Are Your Fellings On This Thanks

 

Slushing compound was designed for and has been used for some time to coat aircraft fuel tanks to PREVENT rust particles from plugging the fuel systems since airplanes sit for extended periods of time with empty tanks. The FAA would have quickly banned it's use if airplanes were falling out of the sky from it. If you buy an approved for aircraft use brand you should have no problem with it. Just be sure to give the tank a hot soapy water and handfull of nuts wash followed by an alcohol rinse (or what ever prep the product manufacturer requires just before treatment to be sure you don't already have a light rust film started after the boilout.

 

where can i get this approved for aircraft sealer can not find any listed that way many thanks

 

You can get good tank sealer kit from any motorcycle shop. comes with everything you need just follow the instuctions and you shouldnt have any problems. We have been using it in bike, car and antique engines for yrs. with no problems. About 30.00 bucks

 

The aircraft slushing compound can be found at the private plane maintainance and repair facility at your closest larger airport. The motorcycle, antique auto restoration suppliers, Eastwood, etc are selling the same product repackaged.
The heavy use of road salt in Buffalo where I grew up was very hard on gas tanks. An aircraft mechanic customer at the service station where I worked told us about slushing compound long before it was sold for automobiles. It saved us a lot of redos to fix new pinholes or weaping on tanks we repaired once we started using it. Never had any problems with it.

 

thanks AXracer , you guys are the best

 

Any body with a truck that old ought to have this web site; www.thefinishedlook.com
They are distributors of POR-15 (paint over rust) and have a gas tank sealing system. It will seal pinholes and even larger if you follow directions. I used it on two '56 tanks after the radiator shop got done cleaning them.

 

thanks for the web site. I've heard of that por-15. I'm going to have to get that and use it. They say that is good stuff.
