ignorance. I'm running a DZ with a vent line and apparantly leaking fuel
on downlines in a BIG way. How do you have the check valve setup on
the vent line??? Are you removing it to fill the tank?

placed in a cumbersome location makes it hard to attach your overflow tubing
onto, when filling the tank. Vent fitting in close proximity to the fill fitting
makes that much easier. I just don't care to overflow fuel all over the ground.
It's a matter of convenience and/or preference<BR><BR>MattK<BR><BR>

both my O.S. 140 RX and Mintor, and never had a dribble issue. At the table I
tend to dribble, but that's another issue! One thing that works well for many
is to run the tank vent to a place well behind the tank. If the end of the
vent line is both behind and below the tank when upright, then there will be
no siphoning problem in flight, or on the ground. </FONT><FONT lang=0

differential pressure. Going the other way it takes <U>about</U> two psi to
get a seal. At a lower pressure there will be some dribble. Is there a
better solution for the tank vent line? Nat
