Product details
CNC Fab Stage 1 HPOP for 2003-2004 6.0L Powerstroke The CNC Fab Stage 1 High Pressure Oil Pump is a reliability upgrade for early 6.0 Powerstroke trucks that addresses a common weakness in the factory pump design. This pump features a new upgraded housing that eliminates the well-known back plate wear issue found on original 6.0 HPOP units. By correcting this failure point, the pump restores dependable injection oil pressure and helps prevent premature pump wear. Ideal application: This pump is designed to support stock injectors and conventional injectors up to approximately 190cc, making it an excellent replacement for stock or mildly upgraded 6.0 Powerstroke engines. Every CNC Fab pump is individually flow tested to verify performance and prevent dead-on-arrival issues. Each unit ships with a test flow result sheet and includes a genuine Ford OEM O-ring install kit to simplify installation. Key Features Fits 2003-2004 Ford 6.0L Powerstroke engines Stage 1 upgraded HPOP design New improved housing eliminates back plate wear Supports stock and conventional injectors up to ~190cc Exceeds typical OEM oil volume Each pump individually flow tested Includes test flow result sheet Includes Genuine Ford OEM O-ring installation kit Injector Compatibility The CNC Fab Stage 1 pump is intended for stock and mild performance injector setups. Excellent replacement for worn factory pumps Works with stock 6.0 Powerstroke injectors Supports conventional injectors up to roughly 190cc Larger performance injectors may require a higher volume oil system Why the HPOP Matters on the 6.0 Powerstroke The 6.0 Powerstroke uses a HEUI fuel injection system that relies on high pressure engine oil to actuate the injectors. The High Pressure Oil Pump is responsible for generating this oil pressure and maintaining injector control pressure. If the pump cannot maintain adequate oil pressure, injector operation becomes inconsistent and engine performance suffers. Common Symptoms of a Failing 6.0 Powerstroke HPOP Long crank or hard starting Hot no-start condition Low ICP pressure readings Loss of power or hesitation Injector misfires or rough running If your truck shows these symptoms, replacing the HPOP is often one of the first steps when diagnosing oil system related issues.
