I have 2 original military fuel tanks for sale that were removed from my S3 Lightweight. One tank weeps fuel from the opening in the bottom plate of the tank 'cradle' (it did this with only about 2 gallons in the tank). I didn't put fuel in the other tank, but I filled with water to check for leaks and found none. I then cleaned it out with acetone and warmed it up to dry it out.
Both tanks were blasted to bare metal, etch primed, and painted semi-gloss black. They have a few scuffs & chips in them now from being handled.
I was going to try to use tank sealer on these, but I picked up a set of Dutch military tanks from the UK. The inside of both tanks appear to be in excellent condition.
I'm not really sure what these are worth, so please PM me if you are interested. Thanks.
Here are the tanks:
