bought this machine new back in '16. been running good until this year. First it stop running in -24 below temp. the gas gauge showed almost empty. so I thought I might have ran out of gas. walked got more gas and filled it up and drove it home. This happened again, this time I changed the plugs, the machine cooled off and it ran a little longer then stopped. each time it stopped running it sounded like running out of gas. Now I'm looking to replace the inline fuel filter. Any idea where this might be on that sled? I looked and looked but haven't found it. it's equipped right? Or do you think it's sounds like something else?
