Because the carburetor also has fuel bowls that act as a reservoir, you're passing much more fluid through the whole system at all times. The larger line slows down the column of fuel, which in theory should create less fuel heating.

I don't know if that's really going to be a huge concern or not though. You can always run an inline heat sink too if it ever becomes a problem.
It almost sounds as if it would be better to run a short loop by mounting the regulator near the tank so no warm fuel enters back into the system?
