check valve lives in the cowl (it just flops around, out of

yes, Matt, that's where I hook my enviro-friendly overflow back to the fuel

<DIV><SPAN class=150423418-01072004><FONT face=Arial size=2>Ok...I'll plead
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?

vent 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

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
