Thumbnail Filmstrip of 7.3 OBS Powerstroke Billet Adrenaline HPOP Dieselsite ADRB95 Images
The ultimate high-volume, high-pressure oil pump upgrade for your 1994–1995 OBS 7.3L Powerstroke.
The DieselSite Billet Adrenaline HPOP is a heavy-duty, bolt-on replacement that delivers stronger, more consistent high-pressure oil to your injectors. Whether your truck is completely stock or running larger injectors and tuning, this pump restores lost performance, improves drivability, and adds long-term reliability.
Why the Billet Adrenaline Stands Out
The factory HPOP is a common weak point on aging 7.3L engines. As it wears, it struggles to maintain pressure under load, leading to injector starvation, loss of power, hard starts, and the dreaded P1211 code.
The Billet Adrenaline solves these issues with:
- Billet aluminum housing — Significantly stronger than the original cast housing. It eliminates common failure points like stretched threads and leak-prone areas.
- High-volume / high-pressure output — Maintains better oil pressure under load than the stock pump.
- Custom internals and design upgrades — Optimized for real-world 7.3L use while improving reliability over the factory unit.
- Every unit flow-tested before shipping — You get consistent, proven performance.
Even stock trucks with stock programming see real benefits: quicker startups (hot or cold), stronger pulling power, better throttle response, and improved fuel economy.
Key Benefits
- Fixes or prevents low ICP pressure issues and P1211 codes
- More pulling power and throttle response
- Better fuel economy
- Quicker, more reliable starts
- Supports a wide range of injector sizes (with proper tuning)
- Billet housing for superior strength and leak resistance
- Proven design trusted by the 7.3 community for over 15 years
Fitment – 1994–1995 OBS 7.3L Powerstroke (Anti-Drainback Version)
This ADRB95 model is specifically built for 1994–1995 trucks that require the anti-drainback feature.
Check your engine serial number:
- 1994–1995 7.3L: Serial # 201680 and before → Use this anti-drainback version (ADRB95)
- 1996–2003 7.3L: Serial # 201681 and after → Use the non-anti-drainback version
All Adrenaline HPOPs (including this one) are designed to work with the later 1996–2003 style IPR valve.
Injector Compatibility
This pump works great with:
- Stock to ~175–200cc single-shot injectors
- Hybrids up to ~285cc (with proper tuning)
Real-world experience exists across nearly every common injector size and tuning combination.
What's Included
- DieselSite Billet Adrenaline HPOP
- Mounting gasket
- Installation O-rings
- Detailed installation instructions
Note: IPR valve and high-pressure oil lines are not included. We highly recommend replacing the IPR valve, ICP sensor/pigtail, and upgrading to stainless braided HPOP lines while the pump is out.
