Thumbnail Filmstrip of 6.0 Powerstroke High Pressure Oil Pump | Atlas 477-0032 OE Replacement HPOP Images
Keep your 6.0 Powerstroke running the way Ford intended. The Atlas 477-0032 is a remanufactured high-pressure oil pump built to meet or exceed factory pressure and flow specifications — so you're not gambling on an underpowered rebuild when injection reliability matters most.
Designed specifically for the 2003–2004 6.0 Powerstroke, this is a direct drop-in replacement. Every unit ships with a new seal kit included, so there's no chasing down extra parts before you get back on the road. It replaces OEM part numbers 1838828C91, 3C3Z-9A543-AARM, and 4C3Z-9A543-AARM.
Why replace your HPOP? The 6.0's HEUI injection system depends entirely on high-pressure oil to fire injectors. A worn or failing HPOP shows up as hard starts, rough idle, misfires, and low ICP pressure — symptoms that only get worse if ignored. A fresh pump restores proper oil pressure and gets your injectors firing cleanly again.
What's included:
- Atlas remanufactured HPOP (477-0032)
- New seal kit for a leak-free install
- Refundable core charge program available

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.
