No, you will not gain horsepower from adding an HPX to your Powerstroke. However, your truck will run smoother and your HPOP will last longer as a result of upgrading.

As previously stated, this does not create more horsepower, nor is it intended to, but the majority of owners see a slight to significant decrease in engine idle noise. This is due to the helmholtz resonance effect that is created from the injectors firing so quickly, and the HPOP (High Pressure Oil Pump) cannot react quick enough to balance/absorb on its own from back pressure spikes within the system. So when the tiny spikes happen, the HPX line sends the pressure back and forth through the heads, instead of hammering on the pump itself.

IMPORTANT NOTE: This line is for the 1999-2003 models, but it will work on the 1994-1997 models, but you must also install the CNC Fabrication OBS HPOP lines due to how the lines are routed on the OBS trucks

Definitely a quality line, worth a shot, it's only $60
This is a very excellent quality line and super easy to install (like 5 mins). I put this on a truck with just 80,000 miles. I didn't notice it to be any smoother/quieter at all. One thing I didn't like was and maybe it was just me but I swear it took longer to start, maybe from having more room for oil? I've since read a bit more on these lines and people seem to be split 50/50, some swear by them, others think it's snake oil or a placebo effect. I've seen the graphs and do believe it works, but I decided to take it off cause I didn't like the slower start and that little slower pedal response I noticed too. I will keep this on the shelf as it is the right length to replace the driver side line. Also it can fit a 94-97 the same way if you move the driver side up from port 3 to 2 or even as a driver side line moving it to port 2. Again definitely a quality line, worth a shot, it's only $60

Will this fit properly on my early 99 7.3?

Yes, these lines should be the same as that of early and late 99 applications. -AW
