Great to see that old bird again. I flew it the following winter in the Grande Prairie area. The unique refueling system used bleed air. You stopped the blades and left the engine running, connected a small air hose to a special bung adapter for a 45 gallon drum and slightly pressurized the drum and voila, the fuel was forced thru the filter and hose and into the tank.
Of course you would never get away with that today with health and safety
