| Subject: | Filter on the fuel vent |
Hello,
Does anyone put a filter on the fuel vent circuit to avoid dust or insects in the
fuel tank?
I recently clean my fuel filter, and I saw some lit tel insects in the filter
Many thanks for your responses.

Hello
How do you inflate your tires on your europa? Do you have a solution to avoid to
remove the wheel fairings ? I want to make a little hole but it seems it will
be difficult to screw or unscrew the valve cap.
Many thanks for your tips or pictures.

I have 5-6cm square hinged flaps cut into the sides of the fairings, secured with
a single screw into a captive nut.
There is just enough room to get you fingers through the hole after you rotate
the wheel so the valve lines up.
If you have the valve caps which have the six sided flats then you can use a small
socket to undo/do up but not too tight.
I then have an extension tube which I screw on to the valve to allow me to connect
a standard hand pump of electric pump to inflate.
I tend to carry a bicycle pump, which is lightweight, in the aircraft for topping
up on trips when needed.

I don't, but the bugs you are getting in the fuel filter could equally be building
nests in an inlet filter, and unlike the fuel filter, you have no backup circuit
for that.

Yes. Plastic mesh-type inline fuel filter (not paper-type filter). This also helps
to break air-locked spurts of fuel rising up the vent line during the later
stages of fuelling.

Hello Olivier!
If you had a filter, do you remember or bother to check it every
preflight? If blocked during the flight, what to do but land.
I have used a modified Cessna pitot cover over fuel vents since 2007
when parked inside or out (its not covering those little pressure holes).
Insects may cause accidents, but also if they happen to lay eggs to your
tubes - a hermit wasps nest is also a known killer.

Alan,
The POH annual Europa Inspection requiring draining and flushing of the tank should
suffice per the POH checklist I would think. The fuel tank vent tube operation
and FOD clearance is an issue missed by many in their preflight and periodic
maintenance.
I personally went to an under-fuselage vent tube with hole under the belly that
is also drilled on the aft side as per the instructions to allow over-boarding
of the fuel when topped off and prevent a direct hit of a bug from completely
clogging the tube in flight.
IF gas pours out of the vent when topping off as I designed it, it is therefore
checked as clear if the fuel drains out.
When parked, I simply cover the vent with a "REMOVE BEFORE FLIGHT" banner cover
when hangered. This is a pain if the aircraft is left tied down on the ramp
as the cover I have is not as tight as it should be and blows off easily. It
is my own fault for not installing a 1/4-inch vinyl hose in the sleeve of the
cover for a firm grip. Same problem with the pitot/static cover. I must get
around to that!
Those with vents on the top are well advised to use a loop of 1/4 inch fuel or
vent line with a "REMOVE BEFORE FLIGHT" flag attached in the center. This loop
of fuel line simply caps both lines on the older by the book vent system preventing
clogging.
See the articles on the Europa Club website for checklist ideas. It is an experimental
aircraft and frankly, as an experimental, some of us never stop experimenting
or finding ways to do things differently and sometimes better.
Best Regards,
Bud Yerly

Hi Group
A few notes on Fuel Vents:
** I owned a 170 that had the flippy pitot and fuel vent covers. I had a dapper
wasp somehow get into the pitot and the airspeed was dead? Took a while to figure
out just how. Then one day walking up to the bird when it was pretty darn
windy, noticed both the pitot and fuel vent flippy covers were opened because
of the wind! Again it was howling and it both were on top of high wing. Anyway
noticed a dapper wasp land and crawl into the fuel vent!! Took a few hours to
clean out a nest that she built. Even though there were 2 holes drilled on the
aft side of the fuel vent, it would not have helped. I suspect with the Europa
being a low wing and my fuel vent on the bottom of fuse, may need more wind
that on a high wing to open
** As Bud has, we mounted the fuel vent on our Mono on the bottom of the fuse.
we too have 2 holes drilled aft. We installed a flippy cover:
https://1drv.ms/f/s!Ah1S270Nwg9VgoFrWgK4zHNaHsxwUg?e=gGz1pO
You need to copy and paste full URL into browser to view
** Am not a big fan of an aeroplane engine (or any other engine as a matter of
fact) that decides to play silent night when not commanded to do so. Have been
around enough to know that if you don't let air into a fuel tank and a vacuum
forms, fuel flow slows or stops. Thus we added a second fuel tank vent to our
Mono that vents inside the cockpit. If one were to do such a thing and just
have a opened tube, besides fumes getting into the cockpit, when you decide to
land turtle and can't get out, fuel can spill into cockpit. We installed a fuel
rated one way diaphragm valve (white with nipples) and in series a Brass fitting
with ball check valve. If you go inverted, the white diaphragm valve should
stop flow, but it's kind of important it doesn't leak, so if it were to leak,
the check valve should stop flow. We also installed a screen filter to keep
snakes out. Using a clear tube, you can blow into it and try sucking to verify
the one way diaphragm valve is working. To verify the Brass ball check valve
is working, by putting a magnet near it and moving, if you hear the ball jiggling,
chances are really really good it will function as designed. If the fuel
vent were to get clogged, it's true that pressure could build in the tank,
and I'm a lot happier to have some pressure in the tank, than a vacuum, just over
the trees. Here's some pics:

| Subject: | Re: Covering vents |
One idea that made sense to me was :
CONNECT all the bright red "remove before flight" covers with string or rope with
an ending in the cockpit with another large "remove before flight" tag on the
end.
This way, once you have the string/rope bundle inside, you know you have ALL your
"remove before flight" covers removed and put them in a bag inside the aircraft
during flight.
Having seen the effects of a friend driving a Beach Baron off the end of the runway,
because he forgot to remove the pitot cover and then reacted incorrectly,
writing-off a nearly new aircraft, I think this makes sense to me ! It also
means that you will not forget to put one or the other of the covers on, as they
will be "loose" on the string whilst on the ground.
Kind Regards

I had a flippy vent cover on my savannah. Accidentally hit it with my
shoulder on pre flight and didn't notice. Since it took off at about 30mph
by the time I noticed the lack of airspeed we were almost in the air so I
decided to deal with the problem in the air. I was surprised how easy it
was to fly without airspeed. Uneventful circuit to land.
So flippy covers not for me after that
