I think someone already suggested this. It depends on whether you are higher elevation than the tanks or lower. If like a Cessna, I think you will drown. If like an RV and the Y is higher than the fuel, I think you will suck air. The previous example was 2 beer bottles, and a superbowl helmet. Did not really know what they meant with the superbowl helmet, but think the deal is whether the tanks one empty and one full is above or below the Y.
