Thumbnail Filmstrip of 7.3 OBS Powerstroke Adrenaline HPOP Stainless Steel Threads DieselSite ADR95SI Images
A true drop in performance HPOP upgrade and the Diesel Site Stainless Steel Inserts Adrenaline HPOP is best available direct fit pump on the market for the 1994-1995 7.3 Powerstroke. The Adrenaline increase flow and withstands pressure loss for much longer than the factory OE pump. The Adrenaline can supply much larger injectors with oil pressure and can support up to 275cc injectors or 550hp. This HPOP upgrade is also a very good OEM replacement without modified injectors. You can ensure a stock truck will run for thousands of miles without loss of power due to weak pressure. Fits the 1994-1995. The HPOP system (high pressure oil pump) is crucial to produce power. Improves fuel mileage making the entire system more efficient. This pump is a true bolt on performance pump that requires no other modifications for installation. Works well with performance modifications or if you want to future proof you unmodified truck to make sure you oil system holds pressure even after the pump is worn many miles from now.
The Best true bolt on HPOP Upgrade
We recommend this pump for modified injectors. The warranty service and performance is top notch. The Adrenaline is the perfect high pressure oil solution for stock and upgraded injector setups. Injectors require a minimum of 2600 psi high pressure oil to fire correctly. High pressure oil is used to atomize fuel coming from the injector. The larger the injector and nozzle the more the pressure drops on a stock HPOP. 2800-3000 psi is the optimal operating pressure under wide open throttle for correct atomization of the fuel. As expected, stock injectors won't feel quite the "wow" that larger injectors will, but you will feel it and when towing you will wonder how you did without it. Larger injectors are the big winners with higher volume high pressure oil. The bigger the injector, the more power gains. Every injector size realizes fuel mileage. But make no mistake, this is not some small increase meant for small injectors. As common sense dictates, the larger the injectors the more power you realize from adding higher volume high pressure oil. This pump will deliver fuel economy, performance, and power to any vehicle. The Adrenaline HPOP upgrade will future proof your truck because it can supply a large range of fuel injectors. Diesel Site is now now backing the Adrenaline HPOP up with a 36 month unlimited warranty.

I would skip Diesel Site products. I had a leak on the adrenaline after 18 months. Full force advised Diesel Site usually only supplied O rings as the warranty. If I wanted to rebuild my own HPOP, I would not have bought the adrenaline. Robert at Full Force is rock solid and took care of me, but Jennifer at Diesel Site ( the part supplier)tried to send the core back to me. I told her the HPOP was warrantied complete as it should be. She then rips me up one side and down the other explaining her vague warranty only covers orings and I should have rebuilt it myself. She goes on to explain that all of this is listed out on their site. I looked up their site see image below.
