Pump design and application
High-pressure oil pumps supply oil for applicable injector systems. Pump, engine and oil-control designs vary.
Match the Right Part to Your Equipment
Include the engine family, high-pressure oil pump number and available pressure-related test results.
Describe whether the system is low-pressure feed, high-pressure common rail or oil-assisted injection. Note where the component is mounted and what tests have been performed.
Diagnose the system before replacing a control part
Check the high-pressure oil circuit, leaks and control components before treating the pump as the only suspected cause.
Pressure, flow, electrical commands, upstream restrictions and return-side behavior can produce similar symptoms. Confirm which circuit and part number are involved before selecting an item.
Part Names and Identification
Other names include HPOP diesel, HEUI high pressure oil supply pump. Check the pump family, complete assembly number and engine application before choosing parts.
