The custom oil pump cover offers both OEM style bottom feed and return oil line placement and custom top side placement options. Fully CNC machined to maintain close tolerance and strict quality control. This pump is not equipped with a rear chain oiling provision. All S&S billet pumps comes complete with everything you need to replace the stock pump and include mounting instructions. Machined with an oil pressure relief bleed off passageway & relieves pressure build up on top of the valve to maintain consistent oil pressure. Oil pressure regulation bypass routes excess oil directly to the supply side of the pump & reduces the amount of oil returned to the tank, less foaming and cavitation. Note: There may be more differences in Harley-Davidson crankcases than you might think. Plugging or drilling a hole is sometimes necessary. S&S offers a drill jig as MCS 518150. This is a special tool that is mounted on the crankcase and used as a guide to help you drill holes correctly.
