POST O Rings replacement

I had a few O rings on the fuel return that were leaking so I replaced then all, just the rings not the entire hoses or injector covers.....I bled fuel system through the schrader valve on the filter.....the question I have is can I just start it or is there another process for the fuel system I must do prior to cranking it up?

yup. just a reminder. only crank for 30-45 seconds, then let it sit for around 2 minutes to let the starter cool off.
21.5 compression gets the starter real hot real fast when trying to crank over a fuel starved engine .

You could always do the ol' ATF in the fuel filter trick since you just replaced some o-rings.
