Even if I bought a new tank, I'd have it lined. Tony, did they have to cut open the TD tank? I have two one not original to the car that is really clean inside but a little banged up on the outside. The orginal came with the car and is firly rusty inside but not perforated. I'd like to have it re-done. I was a little iffy about having them cut it open. Do you think the paint will come off of it, if it is worked on? It still has the original paint on it and I was hoping to keep it that way.
