2012 speedster fuel gauge stuck on full

[Mchannell]

Just filled up yesterday and cruised around for a couple hours. Fuel gauge didn’t lose bars any advise?

Not exactly sure where you should start looking... but check the simple things first.... look at the fuse for the Fuel Gauge that is behind the driver console. I'm guessing that is not it, as if the fuse was gone, it probably would not mark at full? But a good place to look first. Next would be to check the gauge itself, make sure it has a good connection on the back. Maybe try to determine if the needle is just stuck (I have heard other people free up a stuck needle with contact cleaner into a small opening in the gauge at the bottom. After that, I would think it might be the fuel float, which I believe is on the fuel pump cylinder... if you can look at a wiring schematic, you can tap into the wire that sends the signal for the fuel level.
