Melling improved the standard volume GM Gen IV oil pump. To support AFM and VVT components the output of this pump is 33% more than the Gen III standard volume oil pump (Melling #10295). Design changes to the housing, cover, and components together combine to improve the performance, durability, and capability of the oil pump. It can be used in any GM Gen IV application that uses Melling’s stock replacement M355 or M365 oil pumps.
