Standard Motor Products Diesel High Pressure Oil Pump

The Standard Motor Products Diesel High Pressure Oil Pump (also called a high pressure oil pump or HPOP) supplies the pressurized engine oil that powers the hydraulic fuel injection system on many diesel engines. Oil pressure from this pump actuates the injectors, so the pump plays a direct role in injection timing, fuel delivery, and overall engine performance.

Key Features:

• Replacement high pressure oil pump for diesel injection systems that use oil-actuated injectors
• Helps restore consistent injection pressure for reliable starting, smooth idle, and steady power delivery
• Built to meet or exceed the form, fit, and function of the original equipment part
• Backed by Standard Motor Products, a long-established supplier of engine management and fuel system components

A worn or failing high pressure oil pump can cause hard starting, rough running, loss of power, or stalling. Replacing it with a quality Standard Motor Products unit helps bring back dependable diesel engine operation.
