At one time it was possible to damage a fuel pump if you let the fuel get too low. It was the early days of fuel injection, when the pumps first moved to the tanks - they weren't always sitting in fuel, which allowed them to get hot and wear out. It wouldn't happen right away but over time it absolutely would.Has anyone ever read in their owners manual to never let the fuel get down below a certain level because the fuel pump will be damaged? No.
It just doesn't happen.
I don't know how this myth got started to begin with. Maybe if an electric fuel pump ran for a long time pumping nothing it might be damaged.
This was in the late 80's, early 90's, mind you - so it's been a LONG time.
