Would you care to explain the logic behind that statement?


I don't know if he is correct, but a lot of people would agree
with that. The pump is cooled by the gas in the tank and if it
gets low the pump could run hotter.

Part of the pump assembly contains a sealed up electric motor that uses
the fuel around it as an external source of coolant. IE: takes heat
away from it. As a result, the electric motor lasts longer. It doesn't
take a rocket scientist to realize electric motors and heat don't go
well together over time.
