L 4150 Won't Start Need Help

[Al 2]

Hello everyone.
My 4150 has been running great until today. It quit while I was driving it with a full tank of fuel. I changed the filter and without opening the 2 air bleed screws it ran for a few minutes and then quit. With the filter off, and the valve open, fuel drains thru onto the ground. I have had the filter off a couple of times since and then tried to bleed the system using the 2 air bleed screws but no fuel comes out of either one and it won't even fire. Any suggestions would be appriciated.
Thanks
Al

I had this problem after running my L4150 dry. I found that the vent tubing attached to the first air bleed vent valve near the fuel filter was kinked and would not allow air or fuel to flow out of the valve. The tubing was very long looping up near the instrument panel. It was kinked at the top of the loop. After replacing this hose, fuel flowed from a full tank first through the first drain/ vent. and the the one near the injector pump. I closed the first vent opened vent #two and cranked the starter 10 seconds while holding the fuel kill knob as per the manual. I then removed the return tube from the forward injector. Cranking the starter I got fuel - problem solved.
