Not sure but I haven't really trusted Polaris digital fuel gauges for a while. I've been on a number of Sportsmans and my own ranger and I don't find the bar level identified on the instrument cluster matches up very well with what's actually in the tank.
A typical example is when I'm nearly empty it's not uncommon for the fuel gauge to show half tank or more. Kinda scary. But I always bring extra fuel even for a short trip.
I hope you find a solution to your issue!
