Ruining An In Tank Electric Fuel Pump?
Well, I find it hard to believe... Prolonged exposure to air instead of "cooling gasoline" will cause the pump to overheat. Yet I read a long winded thread that had several "professionals" swear...

Consider this; some engines are designed for air cooling and have the surface area to transfer waste heat to the surrounding air. Higher power density engines use liquid cooling because the capacity of liquid to transfer heat is higher than gasses.
So if you drain the coolant from a liquid cooled engine and run it with air cooling it's somewhat analogous. No doubt in tank fuel pumps are designed to tolerate a certain amount of that, however it's not ideal to run elevated temps.
In my experience the in tank pumps are more reliable than the engine driven or remote mounted electric pumps ever were.
