HPOP reservoir not filling
I rebuilt my 1999.5 7.3, I have to fill the HPOP reservoir and it will idle until the reservoir empties. I have a mechanical oil pressure gauge hooked up by the oil filter and it is showing about 15PSI while idling.
I originally put in the HPOP gasket with the screen but replaced it with the one without it after I read online to put in what i took out.
I rebuilt it because the owner before me had a programmer for it. I would hear a strange knocking sound idling after hauling a trailer. Nothing was melted but the rod bearings had been worn into and the pin bushings were a little out of round.
I used the ford rebuild kit. Not sure where to look next any help would be appreciated.
