Driving with a near empty tank is more likely to cause corrosion.

  this isn't technically correct. the low levels are not causing the corrosion. it's the contaminants that float in the fuel is the issue. when the tank has plenty of fuel, those floaters are not near the fuel pump. as the levels lower, the contaminants become more concentrated and are more likely to interact with the pump. at least, that's how it was described to me. by described, of course i mean harped on at every opportunity the parental unit could berate about lack of proper care for the car blah blah blah

    Water (usually what corrodes fuel tanks) sinks to the bottom when it separates. Plus running any other contaminants through your fuel pump is exactly what you want - burn them up and get rid of them, don't leave them floating in your tank until you get a hole in your tank from them.
