Melling oil pumps provide dependable performance every time in every application. Every pump is engineered, manufactured and assembled to the highest material and production standards. Manufacturing processes include state of the art CNC machines and the latest phosphate coating processes. Melling oil pumps are manufactured from high quality materials in either cast iron or cast aluminum as specified by the OEM engine manufacturer. Internal pump parts are produced from sintered metal or steel. Gears are machined to close tolerances to ensure proper engine pressure and correct, efficient pump operation. End plates are precision ground for maximum ware resistance. Depending on application and design, Melling pumps may use gear, impeller or the latest gerotor technology. When completed every Melling oil pump is individually tested for pressure and flow under conditions designed to duplicate actual engine operating conditions. In addition to OEM pump applications, Melling Select pumps are offered for increased oil flow, increased oil pressure, anti-cavitation capability, lighter pump weight and performance when needed. Depending on your oil pump requirements Melling Select pumps are offered in cast iron, cast aluminum or aluminum billet materials. Each Melling Select pump performance level offers a step up in material selection, engineering advantages and increased durability.

Comments about Melling High-Volume Oil Pump:

Not much to say on it's performance because I had to return it & swap for stock volume. It's a '00 GMC Jimmy 4.3 V6 4x4 with the cast aluminum oil pan. Couldn't seem to get the proper 3/8" clearance between pan & screen - couldn't even get 5/16" - so back to the store it went. Figured the HV pump would give me a bit more engine life, since I cheaped out and skipped on doing the crank & big-end bearings, but it's a daily driver - mostly stock except it's got an Edelbrock carb instead of FI, so don't really need the HV anyway. Will be installing the stocker (Melling) in it's place.

      Comments about Melling High-Volume Oil Pump:

      Be sure to buy the melling oil pump screen part# 258S and the steel shaft.

      The stock oil pump screen from my 2003 Chev Express 1500 4.3l has a different tube size from the high volume melling pump, so I've had to return the store to get it.

      Also, you must buy the steel shaft to replace the stock shaft Part No. IS-55E

        Helped improve oil pressure. More oil flow in the top end make sure you purchase the hardened pump shaft it doesn't come with the pump
