Atlas 477-0032 6.0 Powerstroke High Pressure Oil Pump | OE Replacement HPOP for 2003-2004
Keep your 2003-2004 6.0L Powerstroke running strong with the Atlas 477-0032 remanufactured High Pressure Oil Pump. This direct OE replacement is built to meet or exceed factory pressure and flow specifications, delivering the reliable high-pressure oil your HEUI injectors need for proper atomization, smooth operation, and strong performance.
A failing or worn HPOP is a common cause of hard starts, rough idle, loss of power, and eventual injector damage on the 6.0 Powerstroke. The Atlas 477-0032 restores proper Injection Control Pressure (ICP) so your injectors fire cleanly and consistently again.
Key Features & Benefits
- Remanufactured to meet or exceed original equipment pressure and flow specs
- Direct drop-in replacement — no modifications required
- Includes new seal kit for a leak-free installation
- Replaces OEM part numbers: 1838828C91, 3C3Z-9A543-AARM, and 4C3Z-9A543-AARM

04 is a split year. It could have the early style aluminum pump or the late style cast iron pump. If you can send us a picture of your HPOP cover we can help you determine which one you have.

Solo compra la bomba HPOP y elige la opción con cargo por depósito del núcleo (core charge). Nosotros nos quedaremos con ese dinero si no nos envías el núcleo de vuelta.
