The High Pressure Oil Pump, commonly referred to as the "H-POP" found on your 7.3L Powerstroke is like the heart of your engine. It is responsible for creating oil pressure to drive your fuel injectors. If your HPOP is unable to keep up with the demands of your truck because of age, larger displacement injectors, programmers or chips, your truck will never be able to realize its full potential! We offer quality stock and performance High Pressure Oil Pumps by GB Reman, Bosch, and Adrenaline. You can count on our pumps to get the job done!
