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'
