Fellow Europaphiles,

I have come to the conclusion that I do not like the fuel vent system as per installation instructions.  I know there are a number of other venting schemes out there.  I'd appreciate it if any of you could point me to any pictures and descriptions of these alternates.



Thanks in advance to all.



Good building and great flying,

Bob Borger

Bob 

The europa owners forum (www.europaowners.org) has some pics of our set up (G-GIDY) - page two of the gallery under fuel mods. Although it has PFA approval here in the UK we are not yet flying or filling the tank so can't vouch for its effectiveness.  I know others have vented from the tank upto the filler then back down to area around the flap dive rod. I can't find any such pics but Graham Singleton may be able to oblige??



Regards



Paul

Hi  all,

  

 Some time  ago I read on the forum and idea of providing backup fuel tank vent by using a  one way value inside the cabin.  Does anyone recollect who that was,  and  even better, what type of valve was used.

  

 Thanks,

Hello Paul



"Does anyone recollect who that was, and  even better, what type of valve

was used."



Try:

http://www.mcmaster.com/

search 1 way valve

read about check valves



Order a few different types and let us know which one you like.



Take a look below at:

Nylon Body with Viton Diaphragm 

PVDF Body with Viton Diaphragm 



Crack pressure is under 1 PSI, I don't have a feeling just how low a crack

pressure you want. A 1 liter soda bottle with a hole in it to stick in

place a tygon tube connected to your 1 way, and suck on threaded end

should give you a very good feel for what you want.



Once you select a good crack pressure put it in a bottle for a while with

Mogas, and another with 100LL, then check function again. After fuel test

let bake in sun for a while on the dash of your car for a week and try

again.



We know Viton is probably good. Nylon you see being used in fuel systems,

but you need to be careful as there are different types of nylon. PVDF I

am not familiar with, but think it is well worth a $11.05 test.

Ron,

I must have missed part of this thread so tell me if I'm wrong here.  

Are you talking about a valve that will open automatically should the  

vent tub become clogged, and if so what catalog/company does your page  

numbers refer too? I would like to mount one in the filler tube venting  

it into the cabin.

Thanks,

Jeff
