If it were me, I would take the unit out of the tank and visually inspect it. The floating part of the sensor is probably just getting hung up somehow, could be some sort of debris or damage to the float. Worst case, you will need to replace the whole thing which is only about $65 from Babbits Sports Center.

Ok Dirtdemon Thank you kindly for the info. This is a digital display would it it be a float or sensors in your opinion. I'm an old guy but new to this sport.

Hard to say, but I would still take a look and make sure the float unit is working properly, if it seems fine, then I would suspect an actual electrical sensor/sending unit. The reason I am suspect of the floating part of the sensor is that it works when full, but when it has to move, it begins to give false readings and is inconsistent, that kind of sounds typical of a sticking tank float. Also, there are apparently two different models, there is the 650 H1 Auto FIS and there is the 650 H1 TRV Auto. I don't know what all the differences are, but I did notice that the fuel lever sensor unit is slightly different and about $12 more expensive on the TRV model.

This is a common problem and I also had it. Arctic Cat posted a bulletin about and one easy way to possibly fix it is to buy a bottle of Chevron's Techron additive and put about half of it in and the rest on the next tankful. It cleared my issue up for awhile. I also had a weird problem with my SUV suddenly only reading from half to full all the time. I dumped a bottle of the stuff in and it cleared it up in about 2 weeks. That was over a year ago and its been fine ever since. It seems to be sulfur deposits that gets on the sending unit fouling it up.
