Or does a pulse of power switch them back and forth? If they maintain the currently selected tank when power is absent, it seems to me that this could remove fuel lines and a leak prone selector valve from a lot of cockpits. The pdf for that product says "remains in actuated position after power is disconnected" so it only needs power to change - not to sustain a particular selection. -Saro
