> The good news is that the "low fuel" light comes on when there's anywhere from 1 to 2 gallons left, which is plenty to keep the pump safe.

Yeah, but you pretty much have to be under 1 gallon for it to be an issue.

Similarly, for what the OP mentioned:

> But modern fuel pumps have a protective screen or porous sock-like cover that catches any contaminants before they enter the fuel system. And those small bits that might get through would normally be caught by a second filter closer to the engine.

The location requires a filter to avoid that problem, regardless of fuel level. xD
