I have an m9540 Kubota cab tractor. I bailed hay for 4 hours Tuesday 6/7/23. Went to crank this morning (6/8/23) and it ran a little ruff for 30 seconds to a minute and quit. Before starting in the hay I changed all filters and cleaned the water separator. It looked clean but I wanted to make sure. I’m could not tell for sure where the supply line runs from the tank. The fuel filter was empty when I removed it. Any idea on how to proceed would be greatly appreciated. Thanks rl
