    96 SLT 780 low fuel

    MFD is blinking low fuel, even with a full tank. I'm assuming from threads I've read that theres something up with the sender. Any tutorials on checking this. I also so some bypass methods with resistors, but I'd rather have the thing working. On the ski there is a on/off knob for fuel, anyone know what thats for, as it runs fine with it in either position.

    also another question, i had a little bit of whitish residue in the carbs, anyone know what it could be?

    Thanks

    The float in the fuel tank sender unit often becomes gas-logged, and no longer floats.

    You can buy a replacement float from Watcon

    If it has been a while since the carbs were last rebuilt, or they have never been rebuilt, then now would be a good time.

    Have a look here;

    What's the process on getting to that? Looks pretty tight in there. Any idea on the fuel knob?

    Fuel selector valve - perhaps someone has by-passed it. Follow the fuel hoses, and see where they go.

    It is safer to have the shut-off valve working, so you know that gasoline cannot dribble into the engine over time if a carb seal is weak. One owner a while back discovered his entire engine was full with gasoline the next morning - selector valve was left turned on, and the fuel tank vent wasn't venting properly.

    Service or Parts manual should have the fuel hose connections diagram for a stock machine.

    How you get to the fuel sender depends on the model. On many, you unbolt and disconnect the fuel tank and slide it forward, then lift the sender up out of the tank.
