Sorry to dig up an antique thread but I am setting up a new plane with a YS and seems to me with the above setup, when you refueled thru the blue fuel line, you would also be pushing fuel towards the 'carb' at the same time, right? No big deal? My engine is mounted inverted so I am thinking some of the fuel will just flow out the carb instead of filling the tank.

Doesn't come out the carb when fueling.

As long as the tank can vent and the fuel regulator is good, it shouldn't drip out of the carb.
