Thanks for the part numbers and advice. My fuel line isn't double flared (Must not be the original fuel line, perhaps because of the 1971 engine in my truck). It's got a bulge at each end so that a rubber hose can attach with a pipe clamp. I've never seen a tool for doing that. I can't tell what the inline tube line looks like because there isn't a picture of it, but I'm guessing its double flared, so what should I do?
