If you think about how this works in an EFI vs a carbureted platform, it makes a bit of sense.
There's far less pressure in the fuel lines when running this system carbureted, so there's more fuel flow (flow increases and pressure decreases) which would cause some friction heating as the fuel flows through the lines.
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.
