No fluid at rear brakes

The MC is brand new. I used it for a few monthes with no problems until I put in new lines. I'll bench bleed it again just to be sure. Now that I think of it I did have it apart to get it powdercoated. If I assembled it wrong could I be getting a problem like this? I just read a thread that said the front of the MC is supposed to be plugged into the top of the prop valve and the rear goes to the front bottom. Is this correct? I cant seem to find any images online to see how its supposed to be.
