How does a turbine fuel pump work?
The fuel pump receives fuel from the airplane fuel system. The low pressure boost stage of the pump pressurizes the fuel and sends it to the fuel/oil cooler (FOC). The fuel flows from the FOC, through the fuel pump filter element, and then to the high pressure main stage of the pump.
Does an electric fuel pump need a return line?
A pump does never need a return line. A pressure regulator can need one though. The pressure regulator is placed between the pump amd the engine, and keeps the pressure constant, which is needed to precisely deliver fuel.
