HV Oil Pump/rear cap bolt clearance?

Hello, I can say that I had the same Issue with using a HV Oil pump with the standard oil pan, meaing the pump would hit the back side of the pan not allowing it to sit flat. Inside the instruction received from the oil pan company there was a write up on how to shave the corner of the pump to allow it to sit flat when using a HV pump and a standard pan. If you need me to send you a copy of the instructions please let me know...
And to sucking the pan dry, I can say that I have a constant 60 PSI no matter how hard I drive the car, seems to me that i have never sucked the pan dry.

Thanks
