i've heard of people putting wood screws in a gas tank and shaking it like crazy. don't know how well it works because i've never had to try it. so good luck

Insert a length of chain. Tumble. Use a magnet or a wire hook to remove the chain. Its easier than trying to remove a bunch of screws or whatever. If it wasn't bad rinse it with diesel and use. If it was really bad, use a product called Red Kote. The prep is critical but it works great. I've used a gallon or more on a large 72 Cutlass fuel tank to seal a rusted seam. Its still sealed 12 years later. I've used less than a cup to seal a rusty pitted kerosene lantern tank. Still sealed 4 years later. I'm going to buy more to do the tank on my recently aquired 100.

What I've done in the past with my vintage motorcycles is take 1 part molasses and mix with 5 parts water and add to a steel fuel tank (it will dissolve aluminum). The rusted part must be fully submerged. Let it sit for 2-3 weeks, drain and it comes out like new. This works great with anything steel that you don't want damaged from sand blasting. Best thing is it can be reused a couple times and when done dumped out without having to dispose of chemicals. I don't know how it works but I've used this method many times with great results.

Here is a link describing the molasses method.

I had the radiator shop boil out my tank and then they installed the coating to the inside of the tank. They even came and picked it up for me. 3 years later, still working great. It didnt cost me a dime thanks to connections which make the world go round. I have also tried the chain in the tank method which seemed to work ok, but make sure you have a time and some good stamina.
Just my 2 cents
