Okay so my son had a 95 7.3 powerstroke and had the high pressure oil pump built up for high output and ended up keeping this pump when he sold the truck. He bought a 99 7.3 powerstroke and put this pump in it and immediately it would not start, switched the pump back to stock pump and still would not start so robbed an IPR valve from another truck we have and the truck started right up. Then as yound men will do he re-installed the high output pump into the truck and you guessed it ruined another IPR valve. Do any of you guys know if these IPR valves can be re-built since now I'm short one IPR valve and they are not cheap.
