DieselSite ADRSI Adrenaline High Pressure Oil Pump with Stainless Steel Threads

The DieselSite ADRSI Adrenaline High Pressure Oil Pump (HPOP) is a true drop-in performance upgrade engineered specifically for the 7.3L Powerstroke. The High Pressure Oil Pump is the heart of the 7.3L's HEUI injection system — it generates the oil pressure required to fire every injector. When the factory pump wears or struggles to keep up with demand, the result is injector starvation, power loss, reduced fuel economy, and the dreaded P1211 fault code. The Adrenaline HPOP is DieselSite's proven solution.

This pump is completely rebuilt to deliver substantially higher oil volume than the stock unit, maintaining optimal operating pressure across the entire RPM range. The stainless steel reinforced thread inserts (indicated by the "SI" suffix) address a known weakness in aging 7.3L platforms where pump housings can suffer thread wear, ensuring long-term durability and a reliable seal.

Key Features:

• Direct drop-in replacement — no modifications required for installation
• Delivers sustained oil pressure exceeding 3,000 PSI across the full RPM range
• Supports injectors up to 275cc and up to 550 horsepower
• Stainless steel reinforced thread inserts for added durability in aging engine housings
• Completely rebuilt to deliver substantially higher volume than the OEM pump
• Resolves P1211 fault codes caused by inadequate high pressure oil supply
• Improves fuel efficiency by allowing injectors to atomize fuel more completely

• Backed by a 3-year manufacturer's warranty

Whether your 7.3L Powerstroke is bone stock or built for performance, the DieselSite ADRSI Adrenaline HPOP is a foundational upgrade that restores and surpasses factory oil pressure, unlocking the full potential of your injection system.
