Message After my rebuild, I pulled the plugs and cranked the engine for an uncomfortably long time without building any pressure. What I ended up having to do was use a shop vac to pull some oil through. I pulled the filter adapted a piece of clear tubing to the vac that was tight fitting to one of holes in the filter tree (don't remember which one). Then I cranked the engine while my son ran the vac and told me when oil entered the clear tube. After this I reinstalled the filter and it built pressure nearly immediately the next time I cranked it over.

Maybe I just gave up too soon with just cranking the engine, but this worked for me. In case you have trouble too, give this a try.
