On my setup I've been having trouble with the pump sealing against the case and a small leak. I've been told to use honda-bond sealant from honda for this but haven't tried it yet. I believe you do need to clearance the drive pin for the pump for a type 4 but I haven't done it myself. Pressure wise I get 25-30 psi cold at idle, and 15-20psi hot at idle. Higher up when hot I get 55-60psi at 7500rpm which is pretty good. It's pushing through a double filter and a 10"x15" oil cooler before running back to the tank without issue too.
