Most any restoration parts supplier for our trucks will have the reproduction brake and fuel lines. Personally, I order all my restoration lines from Inline Tube directly. They have pre-bent lines for most popular vehicles, including the 1957-1960 Ford trucks, available in original tin-coated steel or stainless steel versions. If your line isn't listed, send them your original. The original part will be 3D laser scanned then bent on an automated machine. Their reproduction fuel line for the 1960 F-100 was slightly off, so I sent them my original line. A couple weeks later I received an exact copy of my original line, free of charge (they probably used it to update their pattern). The only difference between the old and new was the lack of rust on the new part--everything was 100% exact. They will also make custom lines. Good luck with your project.
