I have a 2012 500 HO that is leaking gas out of the clear plastic tubing that is attached to the carb bowl. there is a small plastic disk attached to the tubing in line. The tubing runs to below the skid plate. I unscrewed the bowl nut and drained the bowl but it’s still leaking. I keep the ATV in the garage and the gas smell is getting to me.

Any ideas how to stop the leaking?

Thanks
