U20 - 2000 oil pump bottom housing gasket. Includes outer oil pump gasket. Why not open the bottom plate of your old pump to inspect the gears, shaft and housing for debris, galling etc. before installing an old pump back into a fresh rebuild! Special thin film stock like original. It is important that this gasket be the correct thickness and ours is.Hand cut home made thicker copper gaskets with funny oval shaped holes and mythical non blow out features make zero sense.The original gaskets never blew out.
By the way, this gasket is now included in our deluxe U20 full gasket kit. Shop and compare!!!
