How much gas can you carry without it leaking?? Maybe in January we might be getting together in Longmont and do it at Hoss's????

I have had success with the Eastmans kits that Timbo1 mentioned. I pull the tanks and weld up the holes first then use the kit to seal up any minor pin holes around the welds. No leaks so far.

To clean the tank I put some rocks inside then strap it to my tractor wheel and drive around for about 5 min. this knocks all of the rust loose. Works for me!

I can hold about 8 gals safely w/o leaking. If i put in 10, if definitely leaks. The big problem is that it's my daily driver / only vehicle

A quick gas tank repair is a bar of soap. I has a leaking seam on my 69 D100, rubbed some plain old bar soap on it and it never leaked again in the next fifteen years I had the truck.
I also used that same trick on a motorcycle tank that developed a stress crack over two inches long. The three gallon tank would drain in about five minutes. I worked the soap into the crack and put some duct tape over it to protect from any water that might splash up. It never leaked in the two and a half years until I was able to get it brazed shut.

Even if you fill it up with water? Wouldn't that eliminate the gasoline vapor issue? Just an idea I've heard of.

I've heard of filling the tank with water, but I never tried it.
You can take it to a radiator shop and have them boil the tank, then it's safe to weld on for a few hours. Then the gas vapor returns as it's locked in the crystalline structure of the metal, so don't wait too long.
Another way is to fill the tank with an inert gas like CO2 or nitrogen prior to welding it up.
BTW, I learned about all of these methods when I was getting my Airframe and Powerplant licenses (aircraft mechanic) twenty five years ago.
I learned about using soap from my dad even before that. He learned it from my grandfather who, among other things, was a heavy equipment mechanic.

I've heard of the water and CO thing but I've also heard of them blowing up anyway. We might be able to solder it or what about getting Phill's old tank and repairing it?

Robin, I got your voicemail. Thanks for the info. I'll look into the POR-15 product.
