Two lines or three?
Why are some of you people turning your planes upside down to defuel?????
I don't get it. I use 2 lines, one to the carb with a T and fuel dot and the other from the tank vent with a few coils then out the bottom of the plane.
A hand pump will remove every drop of fuel from the tank provided the clunk is back far enough.
Maybe I'm missing something.
