I'm about to start some welding on my Coupe deVille-just body repair work-and have a dumb question. Do I have to remove the fuel tank? Seems like some people will tell you "absolutely, yes" but every time I've had exhaust work done, I've sat there and watched the guy just go to town without taking out the tank. He did his welding outside though, I'll be in a garage. Not sure if that makes a difference. I've also read stories in welding books about guys welding on an oil tanker truck and having it explode on them...something about fumes coming from the tank being ignited by the sparks. Sorry for the dumbass question but I don't know anyone personally who does this kind of thing, I'm on my own here. Just don't want to blow myself up. THanks.
