Seems logical to me so I am also considering a fuel cooler on the return line to the tank.
Any input would be helpful...

I GOOGLED thermal expansion coefficient for gasoline.0.000950 is the value given,and at one site,they ran a calc for a 10-degree C variation in temp,which gave 1% change in volume.
Since most tanks are air-cooled,and a very small return volume is mixing with a very large tank volume,and the tank volume is cooled as the car moves,the actual tank fuel temp increase may be insignificant.
A belly pan would change the equation.
