Graham,
How true. I don't think Mr Funnel is even 120 microns. Ultralight news
tested it at .005, which is about 120 microns but who knows. We are not
labs.
I have not been a fan of gascolators as I am in Florida, and have never
seen water in a Poly tank from sweating, but I am sure it is possible.
My fuel drains seem to work, and the filters supplied catch the crap and
the float bowls, have always been clean ((ish) except for in line debris
post filter I failed to clean once) and the filters allow me to switch
tanks when the filter begins to clog (noted from the fuel pressure
warning using my FP-5).
A single gascolator, as you know, is a single point of failure, and many
have installed two. Why not have two filters and a tank drains as the
manual indicates. I thought that was pretty sound.
Andy from Andair at Sun n Fun last year told me the same thing about the
gascolator screen and we shared how to inspect (you can't except to
disassemble it) and clean them. Since then I don't even consider a
gascolator. This is a personal preference. Filters are clear to see
in, easy to change, cheap to buy and good enough for me. A quick
disconnect makes it a breeze to pull out and take to the bench and
service without dripping all over the place. If I had a Marvel Schebler
Carburetor I'd use a gascolator. You can drive a truck through the
orifice.
As for old Jerry Cans, cleanliness is next to Godliness, pay attention
to where you get your fuel, Mister Funnel only is a catch for big stuff
and water when refueling in the rain. Keep an eye on your filters,
clean your tank annually, inspect, inspect, inspect, and throw your
filters out every 25 hours along with the old oil and filter...
Ground your aircraft and your Jerry Can. Those wool sweaters and
plastic bed liners can generate quite a spark. More on fueling at Rough
River.
Thanks for your insight as always.
Bud.

an English 914 tri gear had his Andair mini gascolator block. The rust
---From an old Jerry can passed thru the Mister Funnel he always uses. The
mesh of the Andair is 70micron, Mister funnel 120 micron,(check that
figure) Just one more obscure gotcha.
Andair told me their problem was that Rotax specify 100micron and they
can only source 70.

Karl, Dave and Graham,
I use a Mister Funnel and very clean Jerry Cans. Our local Florida
stations have ethanol now, and as an experiment am running it full time
without incident so far. Ethanol cleans the tank very well. After the
third tank of gas run through preflight I filled the filter. After 1
hour of flying time I noticed a slight fuel pressure drop and switched
to the reserve and pressure returned. Clogged filter. Haven't had a
problem since.
The fuel filters stay clean, but I have noticed all but my post pump
R9 fuel lines (Goodyear) are smelling like a gas leak. Next oil change,
all the fuel lines are coming out. It seems that the inside of the
older fuel injection lines (Discount Auto Parts) are swelling a bit as
well. I have noticed the inside of the drain lines sloughing off a
whiteish material and am concerned. I flushed my lines with denatured
alcohol before installation but did not run a small cleaning cotton
through them. I have not seen water or growth in my tanks or my long
sitting fuel cans.

Dave and Graham,
I am puzzled by all this fuss about fuel contamination. Why have I
never heard about a car having this problem ?
I have never noticed anything more than a spec of dust in the Andair
gascolator. I also buy most fuel from new gas stations where the
turnover is high, and pour it through a funnel with built-in sieve. And
I keep a full tank through the winter months.

Hi Graham,
It was a 914.
We have both tried using filter funnels while fueling, however the
process is painfully slow, so we are back
to using fuel straight from plastic jerry cans. We use Shell premium
which has been very clean, and in Ontario
there is no ethanol in it

Hi Dave
most contamination gets in when fuel is added. Rust from Jerry
cans is not uncommon, also algae from old fuel. You really need separate
filters so that if one blocks you have a get down safely reserve. 914s
tend to be more of a problem because of the high flow rate.
