New Oil Pump made by Aisin, same manufacturer as original. This pump will fit directly in all 2F and 3F engines (7/76-90). This pump WILL fit 10/73 thru 6/76 which has a different foot. It will work on these models but your will not retain the same pickup. This is a more superior design. This is a must if you are rebuilding your motor. Pump is OE #15100-61011 which retails for over $260! This will get the oil pressure where it should be.
