Thumbnail Filmstrip of 1996-2003 7.3L Powerstroke Adrenaline HPOP Pump Stainless Steel Threads DieselSite ADRSI Images
Engineered specifically for 1996 through 2003 Ford F-250, F-350, F-450, F-550, and Excursion trucks powered by the 7.3L Powerstroke diesel engine (Engine Serial Number 201681 and after), the Dieselsite Adrenaline High-Pressure Oil Pump (Part # ADRSI) is a heavy-duty performance replacement built to resolve low injection control pressure (ICP) and eliminate P1211 fault codes under heavy throttle.
Featuring custom-designed internals that flow significantly more volume than factory pumps, the Adrenaline maintains optimal operating pressure (2,800–3,000 PSI) across the entire RPM range. This pump supports stock injectors as well as upgraded units up to 275cc or hybrid configurations. Note: This unit requires an exchange core return and includes a refundable core deposit.
Key Features & Benefits
- High-Volume Output: Custom internal design delivers substantially greater oil volume than OE pumps to prevent pressure drop under wide-open throttle.
- Stainless Steel Thread Inserts: Features reinforced ports (indicated by the "SI" suffix) to prevent stripping and eliminate common housing leak points.
- Eliminates P1211 Codes: Maintains steady high-pressure oil supply required to properly atomize fuel and fire HEUI injectors.
- Broad Injector Compatibility: Perfectly matches stock setups while easily supporting performance single-shot and hybrid injectors up to 275cc.
- Industry-Leading Warranty: Backed by Dieselsite's robust 3-year, unlimited-mileage warranty.

I’ve been looking to upgrade my HPOP for a while now and after installing this I wish I’d done it sooner. It’s a complete different truck, starts faster, is insanely quiet. So much so that I had to double check that my Hydra didn’t somehow get disconnected. It’s an expensive upgrade but I’m telling you, it’s worth every penny. As with all my FFD orders, shipping was super quick. I would go ahead and get a set of stubby wrenches- save ya a lot of cussin

One element of an overall build on a 97 OSB. First diesel rodeo and install was straight forward, I did have a clean valley as I was deleting the fuel bowl and mechanical pump. I imagine the install would be perceived as more complicated if having to work around the stock fuel system. Can not attest to the difference this stage one pump achieved as it was just one element of many that was done to the OEM truck. What I can say, is this OBS is a completely different truck than what it was for her first 150k. Good lord build it and man does she run ???? Can�t say enough good things about FFD. Five stars for them as well. S
