Hi! All interested in this topic.....
My vent line runs up the starboard door jamb into a large collector
bottle in the ceiling tipped to discharge back into the tank vent line
down at the tank
Then I run another vent line from the raised collector bottle bottom
right over the ceiling to exit into a tiny pill bottle with an overflow
vent alongside the flap drive hinge hole in the fuselage.
None has ever reached there when filling or caused any venting problems,
most of the piping is clear viewing pipe and it is possible to see over
burped fuel going up there and running back !

Max,
I plumbed both the vent lines into the top of the the filler ("cobra")
and thence aft to vent. I did this because I had been informed by a
couple different builders that the vent lines, especially the tank vent,
tend to burp out gas (petrol) while filling and it's best if they don't
burp it all over the fuselage. I can say that it is correct that I get
a fair bit of petrol out of the vent into the filler while filling.
Were I to do it all again, I'd install an even larger vent line, maybe
3/8 or even 1/2 inch, to allow better venting while filling. Filling
rate, for my aircraft anyway, is limited by vent rate and if I try to
fill faster than vent rate it will burp back up the filler neck, all
over you and the side of the aircraft. Fill carefully the first time
to determine just how fast you can fill.

Hi There All,
Browsing on the gallery of europaowners I saw few pictures showing the
vent lines (tank vent and visual gauge vent) going to the fuel filler
and not to the top of the roof as shown in the manual and installed on
our ship. Has anyone input on that mod, was that a specific filler?
Cheers,
