Bleeding Fuel to the Injectors?

I just finished up replacing my head gaskets. I couldn't find any threads that could answer my question. Do I need to bleed my fuel system from the filter to the injectors? How would go about doing so? Thanks for the help in advance.

read your manual, it says how to reprime the system. Yes, you will have to do it, a few times even to get it primed up.. Open the bleeder screw on top of the filter holder, pump the plunger a bunch, tighten the screw and try to start, do it until it starts.

If you are referring to bleeding the high pressure fuel system (after the CP3), then NO, you do not have to CRACK injector lines like on older diesel injection systems. You DO have to reprime the fuel system up to the injection pump with primer pump. Then just turn it over untill it fires.

Thanks for the help!! It just took a cummins and 2 sets of jumper cables through a window of the garage. Now if only i would of payed attention to the return lines better it would be driving. Damn plastic Ts broke at the O ring inside the injector. Talk about a headache now that it's together. And finding them available was even worse. I have over 100 bucks just in 4 Ts but atleast she will be running strong again.
