I always filled up just a bit under halfway. I didn't drive it all the way to empty. I also only use 76 and Chevron gas, no Arco, Valero, or anything like that. Not sure how else the driver would kill the fuel pump.

I fills up at 3-4 dots but a couple times I did let go until the empty indicator light comes on, but. I very rarely flogged it. Crossing my fingers this doesn't happen to me, atleast not anytime soon.

I can't speak for the "Nissan" fuel pump, but based on my decades with cars, it would not be unusual for a pump to go out at 70,000. This is a mtce item much like a water pump.
