I have damaged the fuel pump by doing just that. However, it had nothing to do at all with gas contamination (the pump couldn't care less), and everything to do with cooling (or lack of, due to the extended low fuel condition). I used to live in a hot climate (30oC every day). The pump self-destructed and part of the casing melted. It takes quite a few days of constant driving with the gas light on for it to be an issue. At the time, I was filling up just enough to get me from A to B and didn't think it would be a problem.
