    GP1200R Fuel Sensor Assembly

    Hey guys,

    Had an issue today where my ski was showing it was empty. It had only used about 10-15 litres at this stage. No matter what we did it still displayed as empty. We then filled the ski back to full and started it and no issues. I think its an issue with my fuel sensor assembly.

    My questions are can I remove it by undoing the clamp and lifting it up? Will I need to remove anything else?

    What should I look for once I take it out? Is there a float? Reeds? Magnets?

    Any help appreciated. In the service manual it just describes it as the fuel sensor assembly as a whole.

    Thanks
    Jason

    Welcome to the GH board....

    So it's working now? If so, don't mess with it.

    It isn't working now?
    Can you use a DVM?

    If so, unhook your battery, hoses, and tank connectors, FIRST, and then struggle to take out your sending unit by removing the clamps on the rubber grommet. Don't screw it up. They don't sell the rubber grommet seperate. Up, and to the port/rear is about the best way. You might have to stand on the tank to push it down a bit.

    Once out, unscrew the screws from the outer plastic shell, and slide it down, and out of the way. Inside you will see a sending unit. Look for the fuse Pico-Fuse on the fuel sending unit. It looks like this...



    With your unit unplugged of course, measure across the fuse. If it is a dead short, that is good. If not, then your fuse is blown. You can replace it with another pico fuse. It's 1/2amp.


    If you are handy with electronics, another option is to short the fuse and put in an external fuse, which makes changing it out much easier.

    Thanks hydrotoys,

    It's working now again after we filled the tank to full again. I might ride the ski again and see if it occurs again or it was one of those things.

    If my pico fuse is blown shouldn't it not work period?

    Thanks again great forum I've learnt alot just by reading so far.

    Corrrect. Don't fix it, if it aint broke. Probably one of the level switches wasn't changing states. No biggie. Happens from time/time.

    Just an update for future reference.

    Went out on Sunday again. Same problem after about 15 litres used sensor went haywire. This time I knew no problem so kept riding. Roughly 10 litres later it was back to reading to normal just over half way.

    Not sure was it is/was but I won't touch it for now.

    Hey Mark,

    I'm in Australia so not easily posted. It was fine today I think it was just being picky.
