You are sitting in the pits on a summer day. Averaging temps 85* to 95*. Pit surface, blacktop, stone or concrete, has to be 100*+. Your factory tank, filled with gas, absorbing that heat or a fuel cell that's in your trunk. Metal fuel line about 18 + inches from that same ground. Now all that warm gasoline has to flow thru that small coil of tubing and you expect that gasoline to cool down to what temp? Hot cast iron intake and hot engine compartment, that's a lot of heat to overcome plus the gas temp itself by a small cool can. Iced down intake and carb is probably worth more in performance can luke warm fuel. An engineering friend is going to investigate it this summer. I'll post the results.
