Ok so I replaced my fuel filters and primer doing routine maintenance, and all the gaskets are in the right place, and I went from bleeding the filters to the injection pump to the injector lines and I just cannot seem to get the air out. I've repeated the process probably 25-30 times. And can't get it bled no leaks or holes, and all injectors work. It just won't run.. and it ran perfect and cranked very easy before. I have never had this much problems bleeding off a diesel. Any tips or tricks would be appreciated this is my first long, but not my first tractor or diesel.

Did you put the BIG oring ON THE FILTER>> It goes UP IN the filter head.. NOT ON the filter..

Try a different filter?
Is your primer pump before or after the filter?
When you are using your primer pump are you getting fuel and no air at the injector pump?
Have you loosened your lines at the injectors to clear the air from the lines?

Yes I have opened the injector lines, it's after the filter

How full is your fuel tank, I know my IH 574 has to be almost full to do a good prime job. Some times once it gets bleed to the injector pump a tow works the best to finish the job.
Good luck
