7.3L Powerstrokes came with either a 15 degree HPOP or a 17 degree HPOP. HPOP stands for high pressure oil pump, and it is what makes our fuel injectors work. The 15* pumps were found in the OBS trucks 94-97 and the early 99's like mine. The 17* pumps were found in the late 99-03 7.3's and are a better pump beacuse they flow more oil than the 15*. Your truck should have a 17* from the factory.

is there any thing that you have to do to make it fit or will it bold right up and would it be a good up grade if i was to run small injectors.

To upgrade an OBS to a 17* HPOP pump you also need a HPOP reservoir from an early99-03.

It will run up to hybrids injectors(230-260cc)

Early birds just swap the pump. Nothing else needed except a new gasket.
