Hello,
I wonder what kind of practical size for a FUEL FILETR FUNNEL have proven
to be most suitable for the Europa? From your comments it appears more
practical to rather pre-filter mogas at the filling station into the clean
fuel containers rather than sticking a filter into the fuel fill opening
on the EUROPA SX style on the side.
More specifically, Aircraft Spruce has 3 models, small, middle and large
with 2.5,3.5 and 5 rpm throughput, but significant size differences. Which
one would you recommend? I am filling up my AC first time this weekŠ

Hi All,
I am surprised that anyone ever gets blocked filters after the initial
shakedown. I know it is difficult to clean out tanks after build but it's
definitely worth pumping a few gallons of fuel through the system before
assuming everything is clean.
If you have dirty fuel in your tanks this is an issue that should be
addressed first rather instead of relying on the fuel filters to do their
job. I accept that some of us have less control over what we put in our
tanks than others (ie: if you are purchasing fuel at the airfield pumps).
In the early days I recall that clogged filters were an issue for some
builders. The filters were becoming overwhelmed by large amounts of crud
which should never have been there in the first place - I do not believe
that changing the size of the filter mesh would address this particular
issue.
Personally I never liked the factory system and opted for a gascolator
setup
instead - nothing fancy like an Andair, just the cheap kit builders one
available from LAS or Aircraft Spruce (I priced one at the LAA yesterday
and
they are selling for £60) . The beauty of the setup is that any large
lumps
of crud (or water) tend to settle in the bottom of the gascolator bowl and
will be drained off when you do your do your daily fuel checks - very
little
muck reaches the filter mesh at the top of the bowl (this is a 120 micron
screen).
We are fortunate in that all our fuel is from cans which we insist on
filtering through a fine mesh funnel and we have never found any signs of
a
clogged filter. It is worth noting that metal fuel cans generate their own
debris as the internal paint on the cans tends to flake off and if not
filtered would cause problems if not pre filtered.
For those who have to rely on airfield based supplies if it should be
possible to carry a filter sock (wire or nylon mesh) which could be
dropped
down the fuel filler opening to ensure the cleanliness of any external
sources of fuel. This could even be a permanent installation.
Additionally as a backup, a fuel pressure gauge which would give a visual
warning of low pressure due to a filter blockage.

Christoph,
what bigger that better in this action.
If small, you will loose your nerves - it is so
slow. Refueling speed is also safety issue - less
time to get debris from there and there!
There is also a model with double outport.
I have one large w 2 ports when using home and
carry small one w 1 port in the ac when flying
far.
Yes - It is very unpractical to use it when
filling XS. Use it when filling your canister. In
that way you can filter it 2nd time if necessary.
When filling direct to your ac it´s too late and
one time operation.
Good luck,
Raimo

I agree with Ramio - the bigger, the better. We have the largest size
available (about 8" in diameter at a guess) and we still have to pour slowly
to avoid an overspill.
IMHO it is pointless filtering the fuel going into your fuel cans as the
internal paint (metal cans) has a tendency to flake off. It should be
filtered from the refuelling can or pump when going into the aircraft. Easy
for me to say as we have the old style filling system (located on top).
Not sure how this works if you have the newer side filling system - thinks
you may need to rig a sling to support the funnel on the side of the
fuselage with a length of poly tubing extending into the filler. I'm sure
other Europa owners have cracked this problem.
It is worth mentioning that the fuel cans need to be earthed wherever
possible - not so much of a problem with metal cans.
I believe one Europa was lost to fire when a spark from can to filler
ignited the fuel. I think if you buy an aviation specific funnel (ie: Mr
Funnel) it will be made from conductive material but you would lose this
benefit if you extend the pipe with poly tubing. However it is relatively
easy to earth the filler opening with your finger and then ensure you do the
same with fuel can before commencing the fill.
I think the problem with static is generally associated with plastic cans -
perhaps someone with better knowledge on this issue could comment.

Hi There All,
I'm a bit puzzled with this topic or maybe I miss something: never had for the last 42 years any trouble of debris in filters on my (numerous) cars nor with my motor bikes (namely BMW using Bing 64 carbs). Why should have I using the same SP98 carried from the fuel pumps via clean cans (assuming the tank of F-LH is clean after 10 years of service and the pipes are Mogas compatible) ?
