Ok I've been fighting this kubota since January and have tried everything I can think of. Engine is not getting fuel. I finally had it running at idle for 45 min today, shut it off, restarted and ran for bout 5 seconds before dying and once again is not getting fuel. I've already done: clearing the vent tubes in both tanks, cleared all lines, cleaned sediment bowl, new fuel filter, new lift pump, drained tanks. I've also tried bypassing the sediment bowl. Nothing seems to work, I'm so aggravated with this tractor. Sometimes when I can work on it long enough to get it running it will be at full throttle at 500 rpm. Sometimes it will run great for 45 min or so then starve for fuel again. When it is running the sediment bowl only stays about half full. Btw it's a 2003 m9000 cab 4x4 with 1500 hours. Somebody please give me some suggestions before I roll it off a cliff. Thanks
