Product Description
The High Pressure Oil Pump is one of the most vital components in your 6.0L Powerstroke’s fuel injection system, supplying the oil pressure that drives each injector. A failing HPOP can cause hard starts, rough idle, poor throttle response, and even complete engine shutdowns under load.
That’s why Sinister Diesel takes no shortcuts. We’ve tested and compared countless remanufactured pumps—and this is the only one that met our standards for precision, longevity, and consistent oil pressure delivery. Each unit goes through a detailed remanufacturing process, including full disassembly, ultrasonic cleaning, component replacement, and the addition of the upgraded STC (Snap-To-Connect) fitting kit to eliminate a well-known OEM failure issue.
This pump provides the pressure consistency your Powerstroke needs for clean fuel atomization, improved cold starts, and smooth performance across all driving conditions. Whether you tow, daily drive, or demand high performance, this HPOP delivers the reliability your engine deserves.
