bobcat ran out of diesel

Monte Davis My son ran the bobcat out of diesel and I think there is air in the line but I do not know how to drain the air out of the line??? any pointers? it is a bobcat 743
Paul On top of the fuel filter housing, there is a bleed screw, you need to use the hand primer and pump that with the screw open until all the air is out, then close the bleed screw. Next you need to loosen up the nuts on the fuel lines going to the injectors and crank the engine over until all 4 fuel lines have fuel leaking from them. then tighten the lines and it should start after cranking it enough, if it starts smoking, keep cranking and it will start.
Monte Davis thank you Paul, I will try this in the morning and report,,,thanks again.
Bryant Hepstall Having the same problem. Also was wondering what is a good way to tell if the glo plugs are good or bad? bought this bobcat used.
Old Gray Dog Monte was spot on for advice here Worked like a charm for me today. Couple of hints fro the mechanically challenged like me. The bleed screw is brass and has not just a flathead screw slot but also a edge that a small channel lock can grab on to to turn it. The hand primer is like the old out board motor fuel line squeeze thing a ma jig. Follow the fuel hoses up from the fuel filter to release them to continue the priming process until diesel comes out. And the fuel filter on my bobcat was the smaller of the three filters visable from the access door on the back of the bobcat. Thanks again Monte.
david c I done the prime with the valve open on bousing and was.t pulling fuel.kt would run 4 a second then cut off
