But I was reluctant to suggest this- there is this deltaT thing!
In moderately warm summers a fuel cooler could perhaps be useful, but if you have something really hot like the more than 100F’s experienced a lot of places, the fuel cooler could turn into a fuel heater.
You would have to run a lot of tests before you have enough data to thrust its reliability and usefulness.

You will not get the fuel temperature to rise above ambiently using a cooling device and lets face it if you are dedicated/crazy enough to be flying in 40C or above temperatures you will already have warm/hot fuel in your tank.
In the Australian summer (up to 47C in the shad last summer), I plan all my long flights to commence near first light (cool of the dawn). Stop for a wee break about 2 hrs later - late morning. May fly again, if cool enough but will not take off above 35C - wait until mid afternoon and fly for another 2-3 hrs.
