Dieselsite Adrenaline HPOP 7.3L Powerstroke

Dieselsite Adrenaline High Pressure Oil Pump

The Adrenaline™ High-Volume High-Pressure Oil Pump is the ultimate solution for any injector setup. This heavy-duty, bolt-on replacement HPOP is perfect for all configurations, including stock trucks. Even with stock programming, you’ll notice improvements in performance, such as:

• Increased pulling power

• Better fuel economy

• Horsepower boost (varies based on injector size)

• Faster startups

The Adrenaline has been a trusted product in the 7.3L community for over 15 years. Dieselsite’s units feature upgraded internals and design modifications that improve performance and reliability compared to the stock unit. Every Adrenaline HPOP is tested to ensure it meets the same flow rate specifications before shipment—NO UNIT LEAVES UNTESTED.

All Adrenaline HPOPs, including those for 1994-1995 models, are designed to be compatible with the 1996-2003 Injector Pressure Regulator.

Billet Model Advantage

Dieselsite takes great care to ensure the quality of cores and housings, but some designs on the original cast housings are prone to failure. The Billet Housing option addresses these issues, offering improved thread strength and fixing common leak points for a more robust and modern solution for your engine.

Anti-Drainback Model

Check your engine serial number to determine if the anti-drainback feature is necessary for your pump:

• 1994-1995 7.3L: Serial #201680 and earlier

• 1996-2003 7.3L: Serial #201681 and later
