Thumbnail Filmstrip of 7.3 Powerstroke Billet Adrenaline HPOP Dieselsite ADRB73 Images
Looking for a high-volume, high-pressure oil pump that’s a true heavy-duty bolt-on upgrade for your 7.3 Powerstroke? The DieselSite Billet Adrenaline HPOP (ADRB73) is the proven solution the 7.3L community has trusted for nearly 15 years.
This isn’t just a rebuilt stock pump — it’s a high-volume unit with custom internals and design improvements that deliver more oil flow and maintain higher injection control pressure (ICP) under load. The result? Stronger performance across the board, whether your truck is completely stock or running larger injectors and custom tuning.
Even bone-stock trucks with factory programming notice the difference — more pulling power when towing, better throttle response, improved fuel economy, and noticeably quicker startups.
Why Choose the Billet Version?
DieselSite starts with quality-controlled cores but takes it further with a precision-machined billet aluminum housing. This eliminates common weak points found in factory cast housings, including thread strength issues and leak-prone areas. You get a stronger, more durable “heart” for your engine that looks as good as it performs.
Key Benefits
- Increased pulling power and towing performance
- Better fuel economy (real-world gains reported across many setups)
- Horsepower and torque gains that scale with injector size and tuning
- Quicker, more reliable cold and hot starts
- Helps eliminate low ICP issues and the dreaded P1211 code under load
- Superior reliability and longevity compared to stock or basic rebuilt pumps
- Every unit is flow-tested to exact specifications before shipping — no untested pumps leave the shop
Fitment
- Fits: 1996–2003 Ford 7.3L Powerstroke engines
- Direct bolt-in replacement (uses 1996–2003 style IPR on all years)
- Important: Check your engine serial number for anti-drainback requirements – 1996–2003 engines with serial number 201681 and after use the standard (non-anti-drainback) version like the ADRB73.
Injector Compatibility
This pump supports a wide range of injectors with real-world proven results:
- Stock to 175cc single-shot or split-shot injectors
- Up to 200cc single-shot aftermarket
- Hybrid injectors up to ~285cc (tuning required for best results)
Call us if you’re running a specific large injector setup and want confirmation.
What’s Included
- DieselSite Billet Adrenaline HPOP (ADRB73)
- Mounting gasket
- O-rings for outlet fittings (2)
- O-rings for IPR (3)
Warranty
3-year unlimited mileage warranty (covers defects short of abuse, tampering, or obvious user damage). Every pump is bench-tested; warranty service requires returning the unit for evaluation.
Installation Notes
- Straightforward bolt-in job for most DIYers or shops familiar with 7.3L engines.
- Always replace the HPOP gasket and O-rings during installation.
- Do not reinstall factory check springs behind the outlet fittings (incompatible with Adrenaline design).
- Full installation instructions available from DieselSite.

If I have this HPOP installed on my truck and need to buy a new Alternator, do I need to buy an upgraded alternator?

The HPOP doesn't affect the alternator.
