I had the same thing happen to me with a 66' Mustang (with a block mounted mechanical fuel pump). It left me worried I would get stranded every time I took the car out. Here's what I did:

Any fuel line close to the headers/block/radiator I wrapped it in aluminum foil and then black insulation tape (you really couldn't see it). .I also re-routed the line from the pump to the carb. It was metal but I switched it to rubber.

Later when I swapped the motor and I ran an electric pump. I routed the line along the frame rail (keeping it away from any heat source) then to a regulator on the pass firewall. I then continued the line along the back firewall and sent it into the holley from the back. It's a much cleaner look and is very effective.

I did the same thing on the Cobra. Zero problems. What are the details of your system?
