Those metal lines were there to protect the gas lines from heat from the Muffler that fit crosswise in that space ( like a camaro). I took mine out 15 yrs ago when I went FI, and replaced them with Fuel rated hose. No issues so far ( 15 yrs!).

I always wondered why those lines ran back and forth the way they do. I removed mine some time ago when preparing to go to fuel injection.
Thanks for the information. I always learn something new on this site.

Carbureted cars use low pressure, but need volume of flow, the spaghetti allows for enough flow impedence to help with pressure maintenance, but doesn't restrict the volume. Fuel injected don't have that need since pump is in the tank, not on the block up front.

I added a 3/8" line, mimicking the factory bends when I did a EFI conversion. There's really no logic to the bends that I can reason. I followed the existing and ran the fuel return line along the frame in parallel with supply line after the loops...
