I’m assuming the check valve is bad in the head and that would explain why the system won’t pressure to spec . Am I wrong ? Can check valves be replace ? Or do I have to replace the whole assembly

Was the pump head recently rebuilt? If yes , were tappets changed or only inspected? If they were only inspected and installed back in head using same crasher/washers, then You need new crasher/washers ( just to get going to where you need to get) . But a FULL head rebuild needs to be done asap. That is if previosly head rebuild was not done completely with new parts.

I bought the truck with 404,000 on it and have no record of it being done before nor after have I been in the shop for that . So no sir . Your talking about the crush washer part #4984382 ?
