Hello.I have a 930 Case with a Bosch injector pump.It will run fine at idle but when working it for about 5-10 minutes it will start missing and eventually die.Have changed all three filters and still does the same thing.Fuel return line was blown out.Fuel delivery line between the tank and primer pump was blown out.Did notice that with 1/2 tank of fuel,the fuel didn't come rushing out like I thought it should have with the filter housing being below the fuel level.When the tractor does die ther isn't any fuel in the first filter.The pressure relief on top the housing isn't stuck or damaged.Is my pump bad, an air leak somewhere, or is it something minor?Thanks Jeff

Took the primer pump apart and was plugged solid.I want to say thanks for the advice.It was very frustrating and the 930 is all better now.

Take the priming pump out and take it appart. The check valves get crap in them, and restrict the flow. DK

Fuel should come out freely from gravity flow. Sounds like an obstruction, probably in the tank. You're sucking air because the fuel is being blocked. I'd drain the tank and look with a flashlight to see what's drifting around in the bottom. It's also possible you have a screen filter in the bottom of the tank that's clogged, I don't know on this model....
