this is not true...the pump is supposed to be submerged and is the leading cause of fuel pump failure...also besides overheating the pump by running it low as people have stated, you're more likely to suck up more sediment, etc...
also another reason to not have your tank that low is in case there is an emergency and you need to evacuate your town or even hit the road to a hospital because someone got hurt you dont need to be pussyfooting around at a gas station getting gas while they could be sitting their bleeding or in shock etc. or something like 9/11 happens and you're in a big city like NY and need to get out imagine the lines and how quickly the tanks in the ground will empty. because most gas stations get a fuel truck 2-4 times a day
