Bill,
When I take off and my fuel tanks are full, I get fuel venting out of the wing tips when the airplane yaws in turbulence.  Right tank more than left tank.  Stops when I burn off about 5 gallons or so.  I ask another Legacy builder about this and he had the same issue.   I figured it was normal.

I am concerned that the fuel vent check valves may be installed backwards or are leaking.  The fuel tanks seem to vent ok and I have not seen any problems along those lines, but fuel runs out of the vents in the wing tips any time I get much over a half to three quarters of a tank.
 
Anyone else having this problem or have advice?
