<DIV>On the Vivats, the vent line is about 12" total length (90% of which is alum tubing) and exits at the bottom of the fuse at the TE of the wing (tank is right behind wing tube). No check valve.</DIV>
<DIV> </DIV>
<DIV>On only 12 oz of fuel, I have done the P05 twice - I doubt any fuel is leaking out.</DIV>
