When it comes to the 7.3L Powerstroke diesel, few parts play as crucial a role in performance, drivability, and power output as the High Pressure Oil Pump (HPOP). The HEUI (Hydraulic Electronic Unit Injector) fuel system relies entirely on high pressure engine oil to fire the fuel injectors, your pump's health and volume output directly dictate how well your truck runs.

For years, 7.3L owners looking to upgrade from a tired or failing stock pump faced a dilemma: stick with a standard OEM replacement that struggles under high demand, or invest in an expensive, full-competition dual-pump setup.

Enter the CNC Fab Stage 1.5 HPOP (SKU: 424028), engineered to fill that gap perfectly for 1996–2003 Ford 7.3L Powerstroke. 

What Makes this HPOP Different?

Stock oil pumps were designed around original factory power levels. Once you add custom tuning, larger injectors, or heavy towing demands, oil pressure can drop significantly, leading to power loss, smoky exhaust, higher exhaust gas temperatures (EGTs), and sluggish throttle response.

The CNC Fab Stage 1.5 HPOP delivers increased fluid displacement over standard pumps. This guarantees solid, reliable oil pressure across the entire RPM band, even under maximum load or aggressive tuning.

Key Features & Technical Highlights

• Optimized Displacement: Outperforms standard stock pumps to comfortably support performance street setups.

• Direct Bolt-On Compatibility: Fits directly into factory locations from 1996 through 2003 Ford 7.3L Powerstroke engines without needing custom brackets or modifications.

• Built and Bench-Tested In-House: Remanufactured with strict quality control to guarantee leak free performance and long term durability.

• Ideal Injector Support: Designed specifically to sustain oil pressure for stock injectors up to 180cc–200cc upgrades.

Who Is the Stage 1.5 HPOP Built For?

This pump was engineered with practical daily driving and heavy duty utility in mind. You will notice the biggest improvement if you fit into any of these categories:

1. Daily Drivers & Tow Rigs: Maintain consistent injection pressure when pulling heavy trailers up steep grades without experiencing power drop off.

2. Trucks with Single-Shot Injector Upgrades: Running 160cc or 180cc injectors? The Stage 1.5 provides the volume needed to keep oil pressure from dropping below critical thresholds during wide open throttle.

3. Trucks Replacing a Failing Stock Pump: If your original pump is wearing out and suffering from low pressure, stepping up to the Stage 1.5 offers better performance at a price point that makes sense ($724.95 MSRP with core exchange options).

Noticeable Improvements After Installation

Upgrading to a new HPOP like the CNC Fab Stage 1.5 delivers immediate performance benefits:

• Sharper Throttle Response: Crisp, instant acceleration thanks to immediate high pressure oil delivery.

• Smoother Idling & Operation: Cleaner injector firing across the powerband.

• Reduced Smoke and Lower EGTs: Proper oil pressure ensures full fuel atomization during combustion.

• Consistent Power under Load: No more "ICP drop" when demanding max power while towing or accelerating hard.

Supporting Upgrades to Consider

To get the absolute most out of your high pressure oil system upgrade, consider paring the Stage 1.5 HPOP with:

• CNC Fab HPOP Lines & Crossover Hose: Ensure maximum oil flow and minimize pressure pulse waves between oil rails.

• Fresh IPR Valve (Injection Pressure Regulator): Pair a new pump with a clean, functioning IPR valve to maintain peak pressure control.

• Quality Engine Oil & Filter: Fresh, high viscosity diesel motor oil keeps the HEUI system running smoothly for years to come.
