Product Overview
The high pressure oil pump (HPOP) is one of the most common failure points on the 6.0L Powerstroke—and it’s not a matter of if, it’s when. Over time, internal seals wear out, pressure drops, and the pump can fail completely—leading to long crank, hard starts, or a no-start condition.

All remanufactured HPOPs start as original Ford units, and this pump is rebuilt by a Ford-contracted supplier to meet OEM specifications. This ensures proper oil pressure delivery to your injectors—critical for engine performance and reliability.

A properly functioning HPOP should produce 3,000–4,000 PSI at wide open throttle and 600–700 PSI at idle. When pressure drops below 500 PSI, injectors will not fire correctly—leaving your truck unable to start or run. Replacing a weak or failing HPOP before total failure helps prevent being stranded and avoids further issues in your high pressure oil system.

Designed as a direct replacement for 2005–2007 6.0L Powerstroke engines, this unit installs without modification—making it a straightforward solution whether you're fixing a failure or proactively replacing a high-mileage pump.
