Thumbnail Filmstrip of 6.0 Powerstroke HPOP Alliant AP63661 Images
The Alliant Power AP63661 is a remanufactured high-pressure oil pump (HPOP) engineered as a direct-fit replacement for the 6.0L Power Stroke diesel. It restores proper injection control pressure (ICP) to the HEUI fuel injectors, delivering reliable hot starts, smooth idle, and strong performance.
Why the HPOP Matters on the 6.0 Powerstroke
The HPOP supplies the high-pressure oil that actuates the injectors. When it weakens or the high-pressure oil system leaks, you’ll typically see:
- Hard starting or long crank times (especially when hot)
- Hot no-start conditions
- Low ICP codes (P2290, P2291, etc.)
- Rough idle, stalling, or loss of power
This remanufactured unit from Alliant Power helps resolve these issues when the original pump is worn or damaged.
Fitment
Alliant AP63661 fits:
- 2004.5 – 2007 Ford F-250, F-350, F-450, F-550 Super Duty & Excursion (6.0L Power Stroke)
- 2004.5 – 2010 Ford E-250, E-350, E-450, E-550 (6.0L Power Stroke)
- Select 2004.5–2007 Navistar VT365 applications
Note: This is the late-style HPOP (typically used on engines built after late June 2004). Confirm your engine serial number or build date if you have an early 2004 truck.
Key Features & What’s Included
- Remanufactured to meet or exceed OEM specifications
- Bench-tested for proper operation and pressure output
- Includes installation/seal kit (gaskets and seals)
- Direct bolt-in replacement with OEM mounting points and gear drive
Why Choose the Alliant AP63661?
Alliant Power is a trusted name in diesel fuel system remanufacturing. Each pump is carefully rebuilt using quality components and tested to ensure it meets the demanding requirements of the 6.0L HEUI system. It offers a cost-effective, reliable alternative to a new OEM pump while providing excellent durability.
Warranty: 2-year / unlimited mileage warranty.
Important Installation Note
Many “HPOP failures” on the 6.0 Powerstroke are actually caused by leaks elsewhere in the high-pressure oil system (STC fitting, standpipes, dummy plugs, IPR valve, or branch tube seals). Always perform a thorough high-pressure oil system leak test before replacing the pump to avoid repeat issues.
Ready to restore reliable starting and performance to your 6.0 Powerstroke? The Alliant AP63661 remanufactured HPOP is a proven, high-quality solution trusted by diesel technicians nationwide.
