Default Priming fuel system

How can I prime the fuel system after changing my fuel filter? I don't have an extra set of hands at the moment. Is there a simple way to do it? Please help

Bump the starter a few times with everything tight and after a few times start the truck. May run a little rough at first but bring up the rpms for a little and you'll be good.

Turn the key on, bump the starter (but not not let the engine start), and let the key rest in the run position. This will run the lift pump for aprox. 25 seconds. If that doesn't get all the air out, crack the return line banjo bolt on the injection pump and do it again until fuel comes out.

If you loosen #4 half a turn to 3/4 of a turn, air will come out with the lift pump running. Fuel will follow when the air is out of the system. If you can't get fuel or air from there, try the inlet, #3.
