Last few fuel dots?!?

I guess I'll be ready when it happens, but I still don't understand how the fuel pump is affected by how much gas I have in the car (I run it to '--- miles left' pretty much every tank). And if I have to leave several gallons of gas in the car to keep the fuel pump from failing, how is that not a poor design on Nissan's part and ergo their fault? You're damn right if it fails within my warranty period I'm going to blame them. I should be able to drive my car until it's almost out of gas, and almost is not 'I could have driven another 100 miles'

If your running on fumes, the fuel pump will be running hotter = shorter life. I don't know how Nissan quality is but I ran my old '92 Integra till the E light was on all the time. No problems. I personally try to fill when it's down to 2-3 lights
