Running your car low on fuel WILL NOT damage the fuel pumps. Running it OUT of fuel probably won't either. The real risk is the car running out of fuel on the highway and loosing power steering and brake functions, which causes people to freak out.

I'll just disagree with you now, although bmw may have that jacket around the pump
edit, I cant find this fuel jacket around the pump, can you please post more info on where you see this or where you read this? It looks like a normal fuel pump
there's a real reason why all the owners manuals say DON'T DO IT, that is not a myth
