I'm pretty sure the line from the fuel pump to the carb is all steel. The line out of pump that runs to the fuel line on the frame rail is rubber to account for engine movement. All fuel lines should be steel unless they need to flex at certain point.

Yes, originally they were all steel, that I was aware of. What I was referring to was doing the fuel line reroute modification to help with heat soak. Wondering if rubber would actually keep the fuel cooler than metal. Also for keeping enough flexibility to be able to remove the valve cover for valve adjustment.

I only have one vacuum line (besides the pcv valve) and they are in good condition
