Check the photo on Sundown's pump, see the acorn on the side of the pump?
Take the nut off and adjust the threaded stud as this applies pressure on the bypass spring for the pressure relief plunger to control your pressure. Later pumps also have a filter that should be checked.
Unless run dry or with grit or dirt in the coolant these pumps run for many trouble free years.
