In that case the cooler would need to be mounted directly in front of the pump. But I agree, I do not believe we can make a significant change in the fuel temperature at all. That's why I posted I don't think it's a necessary mod in my first post.

The coolest fuel in the system should be in the tank.
In which situation will the fuel cooler dissipate the most heat, running the hottest fuel in the system through it, or running the coolest fuel in the system through it?

Here's another thing to consider if one is serious about adding a fuel cooler: A fully regulated return system has all the fuel flowing through the cylinder heads and returning to the tank.
The stock system returns the fuel to the tank before it get's heated in the heads. Only what the injectors are needing to use is sent to the cylinder heads.
Not to sound haughty or anything, but I'm starting to think that my little oriface bleed off system has some advantages over a full flow regulator system. There's a lot less fuel getting heated up and sent back to the tank.
