Thumbnail Filmstrip of 7.3 Powerstroke High Pressure Oil Pump HPOP Alliant AP63624 Images
The Alliant Power AP63624 is a premium remanufactured High Pressure Oil Pump (HPOP) engineered specifically for the 1999.5–2003 Ford 7.3L Powerstroke diesel engine. This critical component supplies the high-pressure oil required by the HEUI injection system to properly actuate the fuel injectors.
A weak or failing HPOP is one of the most common causes of hard starting, no-start conditions, low power, rough idle, and injector damage on 7.3 Powerstrokes. The Alliant AP63624 restores factory-level Injection Control Pressure (ICP), ensuring reliable cold starts, smooth operation, and optimal fuel delivery.
Alliant Power remanufactures each pump to meet or exceed OE specifications. Every unit is completely disassembled, ultrasonically cleaned, inspected, rebuilt with premium components, and 100% flow-bench tested under multiple operating parameters before leaving the facility.
Key Features & Benefits:
- Remanufactured to OE specifications with premium internal components
- 100% flow bench tested for reliable performance
- Direct-fit replacement for the factory HPOP
- Includes new mounting gasket
- Internal fittings pre-installed in the pump
- Restores proper ICP and eliminates common 7.3 starting and performance issues
- Backed by Alliant Power’s 2-year unlimited mileage warranty
What’s Included:
- Remanufactured HPOP (Alliant AP63624)
- New mounting gasket
What’s NOT Included:
- IPR (Injection Pressure Regulator) valve — transfer from your old pump or purchase separately
- ICP sensor, HPOP lines, or other installation hardware
Note: This pump is not compatible with 1994-1995 Powerstroke models.
