Appreciate any practical info, as I would prefer to > leave this out of the panel. Hello D, I put low level float switches in my wing tanks. A "wing low" light is illuminated by the power from the transfer pump running through the float switch. When the tank is empty (or very nearly so), I will get the light if the pump is on. Once I turn the transfer pump off, the light goes out. The light warns you only if you're trying to pump from an empty wing. The full schematic (missing two isolation diodes) of my fuel management system is in the archives. Bill harrelson@erols.com N5ZQ LNC2 O-320 VA42 Fredericksburg, VA
