It’s best not to go above 70 degrees C on fuel temp try to keep some fuel density but ambient can be 50C easy on a hot day so not a lot of margin there.
Cooler depends a lot on the fuel system. I think the one we use is 10x50x8 Cm and only a small portion is return fuel so flow over the cooler is very low.
