That looks exactly like mine. Doesn't make sense the fuel gage does not work. I'm guessing float must be stuck. I did check it out briefly this evening. Plug on pump looks good. I have to get a tool to remove retainer, but I tried fishing a coat hanger thru filler into tank thinking I might poke free a stuck float but nothing happened. I can't believe the digital gage would be bad. It's a brand new UTV.

Great! Thank you Matt. Probably wont get to it until the weekend. I will let you know. thanks, Joe

Another separate issue is the gas gauge shows 1/4 tank when it's full. Any thoughts Matt? Anyone?

Dummy me. I was pulling my hair out on this problem for no reason. If I was a safe driver and wore my seatbelt I would have already solved this, LOL. I simply took a ride with my seatbelt on. Problem fixed, goes as fast as I need now. For the heck of it, I did unplug the seatbelt indicator wire and it lets the vehicle go full speed also. So, to recap, apparently there is a speed limiter with the seatbelt indicator.

Hi Matt. I have been reading this thread and I think I have a similar issue. I bought a new HISUN HS400 EFI recently. Still in break-in period with about 15 miles on it. This thing starts and runs just fine, like new, but at about 12mph it sputters/stumbles/boggs and does not want to go any faster than 12MPH. Does not sputter in neutral and revs very well in Neutral. Any thoughts on what is wrong?
