I'd consider getting two low-cost digital thermometers with remote-sensing thermocouple bulbs (as @ Radio Shack/Fry's Electronics) and pot them into the return line and tank body,and actually monitor the temps real-time.
Or just take a remote infrared pyrometer and sample each location after a stretch of driving.
The numbers would reveal themselves.
Modern cars must deal with Furnace Creek,Death Valley,California,to,arctic Nome,Alaska,and be able to,and does accurately proportion fuel and air even though the fuel itself is at temperature extremes.You might suffer a slight fall-off in fuel density in the summer,but you'd also have thinner air for the car to travel through,for a net highest fuel economy for the year.
Complete vaporization of the fuel is essential to top mpg.Heat can help,whether from a hot-air intake,or heated fuel.
