So the fuel will more likely evaporiate from the tanks if the fuel selector valve is left on both rather than left/right/off?
The way I understand the system is that whenever the airplane is parked, switch the tank to left/right/off to prevent fuel from going from the high wing to the low wing. It's an open system that will let the fuel stayto keep the fule level with the horizon. So if the wings are not level, the fuel will be (I hope this makes sense). Parked includes sitting on the ramp being fueled. How many times have you gone to check the fuel in a 172, taken the fuel cap off the low wing and had fuel poor out of it because the last guy didn't turn the fuel selector from the both position to any other position?
