Remove the oil pan. Next, take off the nut securing the pick-up tube to the engine, followed by the bolts securing the pump to the engine. Remove the pump and pick-up tube as an assembly, then separate them once they are off the engine. The pump intermediate shaft should drop out of the bottom of the distributor shaft during this process. If there is any possibility that the pump is faulty or if an engine overhaul is being performed, replace the pump, as a faulty pump can ruin an otherwise good engine. Before installation, prime the pump by holding it with the pick-up tube up and pouring a few ounces of clean oil into the inlet screen. Turn the pump driveshaft by hand until oil comes out the outlet. Install the pump intermediate shaft with the collar end in the engine block, ensuring the shaft seats in the distributor. Hold the shaft in place and install the pump and oil pan, making sure to tighten the bolts to the specified torque. Add oil to the engine, then start it and ensure the oil pressure comes up. If it doesn't come up within 10 or 15 seconds, shut off the engine immediately and investigate the cause of the problem, as continued running without oil pressure can severely damage the moving parts. Finally, check for oil leaks.
