Fuel pump return line

Hey boys and girls, when a little $$ frees up, I want to install a fuel tank under the bed of my '63 s/b and get it out of the cab. This will entail new fuel lines and I want to use an electric pump. Edelbrock P/N 1791

I have been reading on here recently about return fuel lines in order to keep the fuel cool. How necessary is this??? How much heat is actually generated within the pump. They have internal bypasses so the vanes just spin until the bowls ask for more right? If it's better to install a return line I'll do it, just hate to do more work than necessary.

What am I missing???

I run a deadhead setup with my electric Carter pump. The issue I think is not so much with crazy heat, its more that hot fuel makes less power than cool fuel.

Bypass systems are also a little more accurate at keeping pressure constant which is of very little concern with a carb.
