It use be the case that you where not suppose to run the fuel lower that 1/4 of a tank on fuel injected cars because it was what cooled the pump and you had premature pump failure.

Is this still the case with newer cars? Ice systems?

The fuel pump is cooled with fuel going thru it.

 

Kind of an 'urban myth' with enough statements that are related to real facts to make it sound plausible......yes, the fuel flowing thru (even the last drops) that help to cool the pump...

 

The vehicle isn't going to run long enough without fuel flow to cause any damage.

 

If the FEH is like my 01 Mustang the fuel pump is suspended in a tank that also provides cooling by remaining full to the bitter end of the fuel.

This tank holds probably a half gallon of fuel separate from the
tank itself. The shop manual shows something like this.
