RE: Running out of fuel on down lines.
Well, you know what they say about opinions. Yeah, fuel falls at a slower rate than airplanes, that's why it moves to the back of the tank, while on the other hand, clunks fall at a faster rate than airplanes and that's why they fall to the front of the tank.
Some prefer flexible fuel line in the tank and some don't, but that doesn't mean one way is better than the other.
I thought balls dropped off the leaning tower of Pisa had settled that arguement hundreds of years ago, guess not.
Have a nice day.
