I would say you have a regulator before the carbs sending 3psi in and a reg or relief valve connect somewhere after the primary reg set at 4 which returns back to the tank.
I would says since your running low pressure and consuming the fuel and very little would be returning to the tank ... ( remember we are not circulating fuel like a closed loop system like the Cooling System) so I;m sure mixed with the rest of the fuel in the tank the temp difference would be minimal ? Instead of metalic lines use braid lines to reduce the heat transfer from the engine to the fuel ?
Do you insulate the tank to prevent heat transfer in or do you use it uninslated to disapate the hot fuel coming back ...
Seems we need to use your car DOUG as a test car ... LOL

My car is a rolling test bed already. So far it is successful. I am still here to talk about it all!
How does Tennessee Tim's system work? The carbs need to be protected from excessive pressure. How can you do that with the pressure regulator on the exit, not the entrance?
The return I think will bleed volume off of the system at full load. I can see benefit to it as a pressure relief to the system with a major restriction to it. Probably some type of an internal pill like on mechanical fuel injection system.
