Flop tube
 
I may be way off on my train of thinking but the reason for the flop tube is to be able to pick up fuel in unusual attitudes. I guess one would have to make sure you are only pulling fuel then via the selector switch from the tank with the flop tube when doing aerobatics so you do not introduce air into the system? As I would think if you were set to both and one tank did not have the flop tube you would suck air? is this correct? Ken

We don't use/have a both position on our selectors in RVs or most low wing airplanes because if one tank ran out first you would be sucking nothing but air when upright.
