It's good advice if you don't know the tank design. In our case, we have clues in the Owner's Manual. First, we're told not run out of fuel--which means no fuel remaining in the tank--because that could result in damage not covered by warranty. We're also told that if we do accidentally run the tank completely dry that we should add at least 1.3 gallons before restarting. Since the pump is the only component in the fuel tank that can be harmed by running running out of fuel, that strongly suggests to me the pump requires at least 1.3 gallons of fuel in the tank for cooling.

Second, the manual tells us the tank incorporates an "empty reserve" without telling us how much that reserve is. I posit that the empty reserve is the minimum amount required for pump cooling, or 1.3 gallons.

Based on the above, I believe once your fuel gauge indicates empty you should still have that 1.3 gallon empty reserve, which should be enough to keep the pump cool--assuming you stop immediately for more fuel. This assumes, of course, that your fuel gauge is dead on accurate. If you want to play it safe, refuel when your gauge indicates 1/4 tank remaining, but if everything is working as it's supposed to there's no real danger of damage until you get to empty.

In-tank electric fuel pumps are cooled by the fuel in the tank. More fuel, more effective cooling. The only situation I can think of a reasonable person to run out of gas is perhaps something perforating the tank. Anyone IMHO that mindlessly drives not being mindful of how much fuel they have should consider public transportation

I believe the tank is pressurized when driving, so it's more than the spring holding the door closed. I get your point, though.

When I was young and dumb, I ran out of gas with a truck that had two tanks. I'm older and wider now (misspelling intended) and much more careful now that the fuel pumps are in the gas tank.

The first truck I had with an immersed pump had dual tanks. I followed the old pattern and ran the back one dry before switching to the front tank. It wasn't long before that rear pump crapped out.

I was once driving my work truck home late at night, and didn't want to stop to fill up. I made it back with no issues, but the poor fool that took the truck out the next day wasn't happy to run out of gas 2 miles from the office.
