Problem with 6.7 pump after filter change

So ordered all new fuel filters to install. I am running 1/2" lines from sump to napa 3528 filter, then to my 6.7 pump then to a regulated return. After changing both filters i didnt get the housing tight enough, so it sucked air and truck shut off. Long story short it will not pump fuel now. I hear the pump turn on and run, but no fuel. Could i have screwed the pump up? I know its a rookie mistake, didnt realize to tighten the housing to the stops. I was pretty snug with it tho, didnt require more than one turn.

It probably has air lock. You need to bleed it somehow.

You would know how to best as your setup isnt factory
