    Low fuel warning in GP1800 with 8 gallons left

    Got low fuel warning with 2 bars on the cluster. Fueling at the pump stopped at 10.5 gallons. With 18.5gallon tank capacity, I think it's a bit premature to throw a low fuel warning, when there are still 8 gallons of juice left. Is this expected?

    Pull the seat and look at the tank. You should be able to see the fuel level. A flashlight may help

    Maybe a calibration issue. Not sure if this can be changed with a computer.

    Was the trailer level, nose low or at least slightly nose high?

    The fuel tank on GP1800 has the filler neck connected at the front of the tank, and not quite at the top. If the trailer is nose low or even near level the gas pump nozzle can kick off when there is still a significant trapped air bubble in the fuel tank.

    On my own GP1800 I try to park with the trailer at least level, if not slightly nose high. When the pump kicks off, I bounce on the trailer a few times which burps out some of the air. A couple more gallons will go in, if I work at it.

    The higher up the trailer nose the less trapped air when filling the gas tank.

    Yes. You can actually look at the fuel level in the tank if you don’t trust what you see from the gauge

    Thank you all. I will check level next time it happens. I was practicing donuts and 180 turns, and I suspect it has something to do with early warning.
