FMBP 10833 Engine Oil Pump

Performance Oil Pump for Ford 351W

This Melling Performance oil pump is a high-volume, high-pressure upgrade for Ford 351W applications. Part number 10833 is built for demanding engine use where stable oil delivery matters at elevated RPM.

Key Features

• 25% more volume than the stock pump for increased oil supply.
• High-pressure design with an adjustable bypass relief valve.
• Gerotor assembly uses an extended drive shaft for added support.
• CNC-machined cast iron housing and cover with phosphate coating for wear and rust resistance.
• Individually tested for pressure and flow under operating conditions.
• Made in the USA.

Detailed Description

Part number 10833 is a performance oil pump manufactured for Ford 351W engines and engineered for applications that need stronger oiling control than a standard replacement pump. The design uses a gerotor set, steel gears, a chromoly steel shaft, and additional cover shaft support to reduce shaft deflection under higher engine speeds. The doweled cover helps maintain bore alignment, while the adjustable pressure relief system gives the pump a tunable operating range. This part cross-references Monroe Shocks & Struts (e.g., 224-123R) for the same application.

What It Helps Address

• Low oil volume in performance or high-RPM operation.
• Oil pressure drop caused by shaft deflection at speed.
• Wear concerns from uncoated pump surfaces.
• Alignment issues between the pump housing and cover.
• Inconsistent oil delivery under demanding engine conditions.

Installation Notes and Tips

Compatible with a wide range of Ford, Mercury, and Lincoln applications listed in the fitment data, including Fits 1969-1973 Ford Mustang, N/A and Fits 1977-1996 Ford F-150, N/A. Verify engine and pump application before installation, and confirm the pickup tube and cover configuration match the engine setup. The fitment notes indicate mounting gaskets are included for the listed applications. Part number 10833 is also listed for Ford 351W use, so application verification is important before assembly.

Quality Assurance

Melling tests each pump for pressure and flow under actual engine operating conditions. The housing and cover are CNC machined, phosphate coated, and built in the USA for consistent performance-focused production.
