    The Facet fp operates through a piston oscilating in a cylinder. Solid particles can seize the piston from moving and destroy the fp. That is why a filter is recommended by the fp manufacturer.

    Facet's recommendation is a general recommendation. It does not relate specifically to the 950 Adventure. The OE filter in the fuel tap is fine enough to protect the Facet pump, so there is no need to add another.

    Facet recommend a 74 micron (0.074 mm) filter. The OE KTM filters in the main fuel tap, and in the two isolator taps, are the same (70 microns +/-).

    I figure the Facet is an expendable item. Just because they're used in airplanes doesn't mean they last forever. I carry a spare under the seat and it's an easy trail-side swap. They're a lot cheaper than the stock pump.

    My first Facet 40171 lasted couple of years or over 50000km. I always travelled with a spare wired up with plug and filter ready to go. It cam handy the night before a rally just couple of weeks ago.

    It died because (I believe) the filter was clogged. I use the recommended steel filter. You can't see anything inside. When I blow on one side and it was much more difficult than a new one.

    I don't want to use another steel filter. I can't see if its dirty or clogged unless I take it out.

    I use a plastic filter now. But I am worried it gets damaged or just not be good enough.

    Other than glass filters and recommended steel filter, I wonder what other inmates are using?

    Any chance anyone will draw a very simple diagram of the direction of flow and EXACTLY how and where the hoses go looking at the pump straight on as it is connected to the bottom of battery box? I'm having all kinds of issues since connecting my facet and I am seeing different set ups here on this thread. I am pretty sure I have it right because the bike does start and run. I'm guessing it wouldn't if the fuel flow wasn't proper. However, I am pouring gas from the carb I think. I have the carb out now to clean it I think a float is stuck but I'd really like to be sure...

    Thanks

    From the shut off valve on the left tank to the filter, to the pump and to the carbs. That's it. You must have installed the pump in the correct direction since the bike is running! There is big arrow on it.

    Not sure where the leak is but you might need two of these for the leak:

    In this pic I see that the line from the left tank is going into the fuel pump, fuel is flowing through the pump out the other side of the pump through the filter and up to the carbs. Correct? Where is the line from the right tank going in this pic?

    Nope. The flow is from the left tank through the filter, through the pump, and up to the carbs. The tanks are connected through the crossover line. You must put the filter BEFORE the pump.

    Routing the flow from the right tank to the left then through the filter, then pump and then carbs means that if you crash and crack your left tank, you are going to have to do some re-routing on the trail.

    Mine goes like this;

    Left tank from main petcock to a T. Right tank from tap to the same T. Line from there to filter to pump to carbs.

    This means that the front left tap is redundant and I use it to tap off of to give fuel to others when needed.

    the lines from the tanks are 1/4" and the lines to the carbs are 5/16" right?

    6mm and 8mm ID respectively to be exact, but you're close enough!
