    Bill; the accumulator mesh filter being the lowest drain check point on the engine before the pumps was clean.

    Correct the Rotax canister filter is after the pumps. I have been using Premium unleaded 95 RON. As for ethanol in Aust premum 95 RON MoGas I have no idea. Ethanol blended fuel is available at other pumps but I never use it.

    Please there is no need to capitalise words in your reply such as “After & Before. In texting jargon that is considered as shouting.
    I am posting this info as a possible help to other users: These & are my findings & observations only.

    Did the staining seen in the filter have the appearance of Iron Rust?
    Water in suspension can get past a Mr. Funnel Filter. I use one also.
    One advantage of Ethanol Fuel is that it eliminates the water issues.

    Sorry if you took offense to the capital letters.
    I am well aware of the shouting reference an also find it annoying if overused.
    The intent was to add special emphasis to the Before and After relationship.
    I wanted to be certain that the filters identity was not overlooked.
    Sometimes the details can be missed in the written sentence.
    Does Italicized look less offensive? :)

    I have been averaging 30 hrs on a final filter. Might be fuel contamination from airport or a question about the efficiency of the final filter?
