What is error code 51 and 58 how do I check gr4ound fault on my sportsman 500 or is it something more common like changing fuel filter

Question edited for clarity.
Question moved to a Polaris Category.

Normally, you would just drain the tank, remove the fitting and replace the gasket. I don't see a gasket though, unless it is just a standard O-ring. That is the way to do it though.
