I am borrowing a BOBCAT 753 series that I use frequently and I am in the middle of a water garden install and problems!!

I am NOT a Bobcat mechanic first off but I pretty good mechanically!

been running the ‘cat for 3 days with no problems as usual. THEN poof she dies.

Had to prime the ball and she started back up for 2 minutes or so then quit again…

I replace the fuel filter and I get about an hour of use our of it again then POOF she quits!! I CAN ALWAYS GET IT RESTARTED BY PRIMING THE BALL BUT IT only RUNS A SHORT TIME. I Just dont want to keep replacing fuel filters.. I would like to fix it before I give it back and finish my job!

What gives? Does this sound like I have crap floating around in the tank?? and it is plugging up the fuel filters rapidly?

HOW DO I DRAIN THE TANK? I hate to call out the local Bobcat service if I dont have to !!

Thanks!
