904 Pump Housing Leaking Between Ports

I checked for burrs and gave a light sand to both halves. No there is nothing in between the two halves. No broken rings. I have the front and rear packs assembled on the bench with the pump and I'm air checking it that way. The clutches are actuating properly when air is applied. It's just leaking over from front to rear clutch. I put my thumb over the port I'm not applying air to and there is enough air leakage to actuate it.

When I first assembled the pump, I installed a used gerotor from the trans shop that pressed my bushings, I'm going to remove it and see if that helps. And torque the two bolts nearest to the pumps ports first.
