This Melling engine oil pump, part number M330, is a standard replacement pump built for dependable oil pressure control. It is engineered with steel gears, a cast iron housing, and a cast iron cover to support consistent operation in stock applications.

Key Features

• Standard replacement engine oil pump for stock applications
• Steel gear construction with gear and gerotor technology
• Cast iron housing and cover for durable pump construction
• Precision-ground end plates for improved wear resistance
• Individually tested for pressure and flow under operating conditions
• Includes gasket or seal

Detailed Description

Part number M330 is designed for Ford, Lincoln, and Mazda applications that use a standard pressure, standard volume gear-style oil pump. Melling machines the gears to close tolerances to help maintain proper engine pressure and efficient pump operation, while the rust preventative finish adds protection during service. The pump uses a drive shaft design and a 3-bolt mounting pattern, with a 16.00 mm inlet size and a 0.630 in pickup tube diameter.

Compatible with Ford Transit Connect, EcoSport, Fusion, Police Responder Hybrid, SSV Plug-In Hybrid, C-Max, Focus, and Ranger, plus Lincoln MKZ and Mazda B2300 applications. This part cross-references DNJ OP446 and Sealed Power 224-43660 for the same application. If you are replacing a worn oil pump on a Ford Focus, Ford Ranger, or Lincoln MKZ, M330 provides a direct stock-style solution for maintaining oil system performance.

What It Is Used For

• Restoring oil pressure after pump wear or internal leakage
• Addressing low oil pressure warnings caused by pump inefficiency
• Replacing a noisy or inconsistent oil pump assembly
• Supporting proper lubrication in high-mileage engines
• Correcting oil delivery issues in stock engine setups

Installation Notes and Tips

Verify engine application, pump style, and inlet dimensions before installation. Confirm the mounting pattern and drive configuration match the original part, and inspect the pickup tube and sealing surfaces during service. Because this pump is a standard replacement design, it should be matched to the original oiling system specifications for the vehicle.

Quality Assurance

Melling manufactures this pump in the USA and tests each unit for pressure and flow to verify operation under conditions that duplicate real engine use. The close-tolerance machining and precision-ground components reflect the brand's focus on consistent oil pump performance.
