In the middle of testing for a HPOP leak,2006 6.0L. IPR fully close and air is coming out of a "port" on the body of the pump right behind the gear. Im not talking about the shaft seal either. Could it be the drain hole for the IPR????? if so, could it be because the IPR is not closing all the way? Where does the IPR drain?
