Walker 20hp not running

I have a 1998 20hp kohler with 1500 hours. been running great untill I allowed the gas to go to the bottom of the barrel. Will run great when fuel filter is full (installed new one) and then it deisels backfires and quits. If itsits for a few minutes it will start up fine but stops again. It seems obvious it is a fuel problem. When I took off the lower hose from the fuel filter and placed it below the tank little gaas came out. I blew compressed air into the hose and heard it bubble inside but still do not get much fuel. I noticed a fuel shut off at the bottom of the tank where the hose meets the tank. it is open but do they fail. Should I have a steady stream of fuel when hose is disconected and bellow the tank?

Any help would be appreiciated.

I think you should have a steady stream of fuel. If you get trash in those shutoff valves, they can plug up. I would take off the shutoff valve and see what kind of flow you have.

does it have an in-tank filter? if so it may be clogged.

did you have the cap on or off when you removed the hose? if it was on, remove the hose and then remove the cap, if it flows then the cap vent is clogged, replace the cap.

check the hose from the tank to the filter, it my have seperated inside.

The gas cap was on and off while I was checking the flow of fuel. It is not a steady stream of fuel either way just a drip. The hose between the tank and fuel filter is new so it should be ok. I will take off the shut off valve to see if it is clogged. It sure is in a tough spot in between the tank and the tank braket,

thanks for your help.
