OM617 losing prime constantly

I had to do the timing chain so the hardlines from the IP to the Injectors came off. I had to replace the primer pump, the original one's O-ring was trashed. I replaced all my low pressure return lines, pre filter fuel filter and the 5/16 fuel lines to and from the tank.

What'd I do wrong, after sitting for 6-10 hours it seems to leak down to the point where it gives me a miserable time starting.

Replacing all the rubber lines helped, alittle, I double checked the seating of the fuel filter.

Did I not purge my injector lines correctly?

HOw many orings on the primer pump? SHould there be one in the bottom? Is it just a matter of not getting it screwed all the way in?

I'm getting confused

if you can offer any help, thanxs
