Considering however how vital oil pressure is for all of those reasons, why would anybody take a chance on reusing a high mileage stock pump on a new or rebuilt an engine?
Older stock oil pumps that are worn can have sloppy internal clearances and reduced output. Wear between the gears, and old springs may hinder a pump’s ability to get traditional flow and pressure the engine needs. Especially if you have built a performance modified vehicle, which demands more oil flow. Like a pro athlete, oil is the blood that pumps through your engine, and the pump is the heart.
The pressure relief spring on used pump will have gone through lots of compression cycles already applied and if reused can run a high risk of failure. A broken spring can enable the pressure regulator to remain open, greatly reducing the flow output of the pump.
