    Fuel coming out breather tube

    I have had this happen only twice and wondered if anyone else has had this happen. I usually only fill my ski before I ride. This time and probably last time but I don't remember as it was probably 18 months ago I stored the ski full. Tonight when I went out I found fuel had come out from the breather tube inside the bar cover and down my glove box all the way to the foot wells. I know they have had a recall but I didn't think it had to do with this happening. I didn't fill it all the way, just until it kicked off and did leave some room in the tank for expansion. Has anyone had this problem?

    Sound Like it is Overfull

    Sounds like you are over-filling your ski. I am not sure what you are riding but you really should stop filling it once it gets close to the top of the fuel cell, not the fuel filler or neck. I pull my seat and watch the level when filling.

    I started loosening the cap now that it has happened twice. Just a touch in case I forget to tighten it again before riding. I will probably just do it each time as the drain plugs tighten it when I put them in a loosen is when I pull them back out. Thanks for the suggestions and I'm glad this isn't something that is very common.

    FYI

    I guess that may be why the say to verify the fuel vent check valve every 25 hours Good advice on refueling too but for long rides I put ever drop I can into the machine and expect a serviceable venting system, not to mention the mess and possible pollution due to a defective venting system. If you are having problems with the valve you could put another one in series for redundancy. Sooner or later you will dump fuel with a defective venting system because we are after all only human and by nature we forget from time to time.

    Periodic Maintenance Procedures
    .
    Fuel Vent Check Valve Inspection
    The fuel vent check valve is mounted in the fuel tank vent
    hose to prevent fuel from spilling during riding. Air can flow
    into the tank to allow fuel to be drawn out by the fuel pump,
    but fuel cannot flow out the check valve.



    Remove the front storage pocket (see Hull/Engine Hood
    chapter).
    Cut off the bands [A].
    Pull out each end of the fuel vent check valve [b] from the
    vent hoses [C].


    Blow through the fuel vent check valve from each end.
    If the check valve will allow air to flow as shown with the arrow on the valve, it is OK. If air will flow through the check valve in both direction or
    in neither direction, the check valve must be replaced.

    overfilling

    seen that a few times. Mystery gas spills, all brands from tanks filled to the brim. Real nasty. Gas expands quite a bit over 20-30 degrees.
    It'll blow right out of a vent valve that's not 100% or worse, blow a line off inside the hull. Really nasty.

    Thanks rotortiller I guess I could have checked the maintenance in the manual but it seemed easier here. I will replace the valve for sure. Oh well my stupidity will help others is one way to look at it.
