Low on gas = odd symptoms

I had a fuel pump fail around 120,000 or 140,000 on my truck, blamed on my habit of running it down to fumes every tank.

I know what you're saying, and I'm aware of how common it is to believe this, HOWEVER, have you actually EVER opened up your gas tank? Go open up your gas tank/get to the area where your fuel pump is, get a good look with a flash light and then you'll understand better.

imz- In my original post (attached), I wasn't saying that they are cooled externally by the fuel sloshing around outside of them (you are right about that)- I stated that "most fuel injection pumps are cooled by the gasoline they are pumping"

I could have clarified better by saying "As the relatively cool fuel moves up, through and out of the running electric fuel pump, heat is carried away from it".
