I'm cleaning my gas tank on my 33 Chevy. Did not notice any rust in the tank, but there was some gum/varnish. Now looking at the fuel line from the tank to fuel pump - it's basically copper tubing. Should I replace ($60 for steel line from The Filling Station) or is there a way to clean my existing fuel line? I don't think there's any rust in the line, since it's copper.
