I have replaced the lift pump and it was not working. Now tractor runs until fuel filter runs dry. I pullèd fuel line from tank to fuel filter and have flow. And yes the fuel shutoff lever is in the o possition. Ready for more great and wise advice.

For the 4300, the "O" is open and the "C" is closed according to the operator's manual.
Fuel should run out with the filter cup/element removed and the shut off valve in the "O" position.. I'm thinking.

IF your sucking the filters dry, theres no fuel getting to them, simple right??
The lift pump is doing its job by pulling the fuel from the filters & up to the injection pump..
The problem is from the filters back to the tank.. TRY loosening/removing the fuel cap.. OR you have something preventing the flow from the tank TO the filters.. good luck.

I have tried both ways. O is where lit was when it ran last. The other choice is marked C i assume for closed.

I took apart the filter housing at the open closed knob and discovered that the nylon valve had broken and either possition was open. I then purchased a new filter housing and installed it. Low and behold when tge fuel can get to the injectors she starts up like she always wanted to. Thanks everyone for the the sound advise.
whsjohn - I know this post is old, you may not see it - I think I am having the same issue - your last post says "the nylon valve had broken and either position was open." - did you mean that the valve was CLOSED no matter what position it was in, so no fuel got into the bulb? I just changed the filter on mine, and it won't start. (It did run for a few seconds, I presume consuming the fuel in the line. Now it won't fire at all.) I wonder if that nylon valve broke when I closed/opened it to change the filter...
Thanks.
Thanks.
