72 Duster with a Rusty fuel system....how do I avoid this???

The tank in my 69 Barracuda was pretty bad on the inside, and 23 years ago I could not find a new one. I used the gas tank liner kit from Eastwood. It worked great. About 12 years later, my gas sending unit died. I figured I'd replace the tank while I was at it, since they were readily available by then. When I looked inside the tank, the Eastwood liner was still looking real good. It was easy to do. I highly recommend it.
