Because of the small dihedral built into the Lancair's wing, the fuel vent
will leak if the aircraft is not within about 3 degrees of being level. 
Once the vent line fills with fuel it will continue to siphon even after
the aircraft is leveled  until the inboard side of the vent line is
unported.    I do as someone else mentioned, and don't squeeze in the last
1/2 gallon which causes the inboard side of the vent line to always be in
the air above the fuel rather than in the fuel (unported).  Also keep in
mind that you need to allow some room for fuel expansion as it warms up in
your tank.  Most fuel storage facilities are underground and probably
cooler that when it sits in your wings for a while on that nice summer
flying day.   If you still insist on getting that last gallon onboard and
want to eliminate the fuel drip from your vent system do like the big boys.
 Vent  the tank to the opposite wing.
