Lynn,
That's pretty interesting. I have been thinking of bending the drain forward like a pitot tube to get the same effect. The one concern is that it may tend to take in debris kicked up by the nose wheel.

I had very uneven fuel flow, so uneven, in fact, that one tank or the other would drain about 3/8 down before the other tank would even start to flow. I traced this to the mini-naca "scoop" on the bottom of airplane acting like a venturi and putting suction on the tanks through the vent line. I laid up a tiny traditionally shaped airscoop, sticking up just 1/4 inch above the fusilage surface, and glued it on over the naca scoop. With my now "pressurized" tanks I have not had even the slightest indication of uneven flow ever since.

I am having a very uneven fuel draw in my XL. My right tank draws substantially faster than my left. I understand others have had this problem. I can transfer fuel with pumps. I would like to know if anyone has been able to do something to get the fuel to draw more evenly?
