Yes he was referring to a transfer pump. Even with a transfer pump, he will not
remove 19 gallons or 72 liters in a half an hour. The lines are too small in
diameter. There is restriction from both the pump in the tank and fuel filter.
Then once the return line is no longer under fluid the possibility of sucking
air if the regulator is of an open center design. Which means you can no longer
pump fluid.
