 The left side of this pump has 5/8" dia. fitting for scavenging the sump and the 3/8" dia. for oil supply from the tank. The right side of the pump has ball/spring check valve and 3/8" dia. oil return line to tank. The front side of the pump body has NPT plugs to block off passages from manufacturing/machining oil galleys. Can't make this pump any smaller and no reason to make it bigger, adding weight. Also the pump sits very close to the right side lower frame tube with very little clearance. \\  The left side of this pump has 5/8" dia. fitting for scavenging the sump and the 3/8" dia. for oil supply from the tank.
