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,

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! 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 !

Look on the new club web site and go to page ”For builder”, “Engine and fuel system”, “Fuel System”,
Under the heading Filler and Vents you will find a link to an article “Fuel Vent” which I wrote.
If you want more details let me know.

I ran 10mm lines on mine, up to the cobra, just below the filler cap, I then ran another line down the back of the cobra
And out through the floor near the landing gear, with a pitot style alloy fitting pointing forward. I had concerns
About suction in flight draining the tank, There is an automotive fuel filter in this line to stop water bugs etc entering the tank
Through the breather.

Please refer to my website for some details on the vent tube out the bottom and a sight gauge that works. The details on the website are general in nature. I have done many of these using the concept of the drawing below. It works, allows overfill fuel to drain out of the cobra, keeps fuel off the top of the aircraft and provides a very accurate fuel gauge. So much so I don’t need any other form of gauge or sender.
[url=https://skydrive.live.com/redir.aspx?cid=2161856909618aa7&page=play&resid=2161856909618AA7!239&parid=2161856909618AA7!238&type=1&authkey=!AP_XK1w434iOGtM][img]cid:01e401cd2022$79373310(at)adminPC[/img][/url]
I keep a short piece of 1/4 inch hose to allow me to assure accuracy in case fuel gets in my sight gauge vent line. If I overfill my plane and believe my sight gauge vent side is full of fuel, I simply put the 1/4 inch line on the inside the cobra tee for the sight gauge vent and blow into it until I hear bubbles in the tank. Sight gauge is accurate as it can be. Just make sure your sight gauge elbow or tee is the highest point in the cobra neck and your drain is lower.
Just an idea...
