6.0 Powerstroke Stage 2 HPOP | Atlas 477-7587

Upgrade the heart of your 6.0L Powerstroke’s HEUI fuel system with the Atlas Diesel Stage 2 High Pressure Oil Pump. Built specifically for 2003–2004 6.0 Powerstroke engines, this performance HPOP delivers 25–30% more flow than the factory unit, giving your injectors the oil volume and pressure they need for stronger, more consistent performance.

Whether you’re running stock injectors or stepping up to larger ones, this Stage 2 pump has been proven to support up to ~225cc injectors — making it an excellent choice for mild to moderate performance builds without jumping straight to a dual HPOP kit.

Key Features & Benefits:

• 25–30% increased oil flow over stock for improved injector response and overall drivability
• Supports injectors up to approximately 225cc
• Upgraded internals with a threaded plug design (a major improvement over the factory press-in ball that commonly fails)
• Includes O-ring installation kit for a clean, leak-free install
• Direct-fit replacement for early-style 2003–2004 6.0L Powerstroke HPOPs
• Reliable, cost-effective upgrade that addresses one of the most common failure points on the 6.0 Powerstroke
