The usual "fed up with my project" rant.

And what do you mean by gas line? Do you mean fuel line (the rubber stuff)? If so, just get fuel injector hose. Holds up better to the alcohol in modern gas. Any auto parts store will have it, or probably even Farm & Fleet or other places. Or do you mean the hard fuel lines? If so, are you sure they need to be replaced? Any store should have that and you can make it yourself, or the kits aren't terribly expensive as a last resort.
