I have a 2009 model MXZ 500 TNT. I have been running it for about 4 years now and the electronic fuel gauge started acting up last season. It'll say it's on empty even when it has a full tank of gas. Started up my machine more than a week ago and bought gas when I forgot the gauge is not always accurate, so I had 14L left over when I thought it was on empty. Has anyone dealt with this problem before?
