Is it needed on a full time puller? I know the stock one doesnt do much, cooling it before it goes into the tank, but would an aftermarket cooler somewhere under the hood help?

Thats what I'm thinking I'm going to do on mine( i know its not a full time puller ) but based on what Ive seen here

the fuel temp increases alot with the air temp under the hood. The longer you idle, and slow speed drive the higher the fuel temp gets and the longer it takes to cool down.
I think I'm going to mount a cooler up front behind the grill with the others.

On Simon's race truck last year I made checks of fuel temp just to see how much heat it was picking up as the aluminum fuel tank only holds about 10-12 gal and he has no cooler. After each 1/4 mile pass with about 20 min of 1400rpm idle for warm up it didn't gain much heat. At least not enough to warrant adding a cooler. Although his fuel system is highly modded from stock, I don't think it's required for a purpose built drag/puller. At least not from what I have seen.
Have you been seeing high fuel temps Rob?

I have a 6gal aluminum fuel cell in the bed of my truck. I was amazed at how much heat the fuel picked up after being returned to the tank. I had a wrap made by Chill Factor to put over the tank while in the pits (especially during the summer months).
I don't like to see anything above 130F. The dual fuelers that I have logged in summer usualy get to 165/175F. I believe you are losing power at 175F. How much? Don't know. The most efficient diesel fuel temp is 75F for diesel engines in boats. I don't see why our trucks would be any different.
I thought about running copper fuel line into a cooler in the bed for my truck. But than had second thoughts that it wouldn't do much with our "smart engines" compared to pulling tractors etc
i am helping a guy with a 3-53 detroit in a 82 chevy and we are working on a design for a beer cooler with 2 copper coils in it for the fuel to flow through (one feed and one return). fill the cooler with ice in the morning and pull all day to keep fuel temps cool.
I cool my fuel 2 ways now, the fuel line going to the main feed block is cold by touch even after it has idled a while. Does it help? Idk, from the info ive seen it sure cant hurt. What Mike said earlier seems to be on track with some of the data i have heard, not from the performance end, but from tractors and oem side of it.
