Phillip I had 2 Facets in my Rotorway Helicopter. The gas tanks are high above the engine, hooked together so that the weight in each was always equal. The Facets were hooked so that the fuel flowed from one thru the other and then a pressure regulator but had individual switches. Leave both running when flying. Great to preflight check out--Turn one off, the engine still runs turn it back on and then turn off the other, engine still runs. They were working as usual when I finally sold it after flying it for ten years.
