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

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.

Hi Karl,
I've never found anything in the Andair, or collected any water from the fuel drains.
Chris got the Algae, now we both buy from busy stations.
He keeps his tank full, I don't, preferring to buy fresh fuel each time I fly.
If the weather ever settles down would be nice to meet up halfway sometime.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> 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.

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.
