It's been noted on OEM stuff for years that people in the habit of running around close to empty tend to need their in-tank fuel pumps replaced. Versus folks in the habit of never letting the fuel go below a 1/4 tank. Their pumps tend to last the life of the car. Everyone's finger points to them running cooler and lasting longer with more fuel.

Short version is that, yes, the cooler you can keep the pump running the longer it will live. And differentials run hot enough that some racers run coolers on THEM. So moving it away from the rear end wouldn't hurt.
