Product Overview
95-03 Ford Powerstroke 7.3L Pressure Oil Pump Lines (HPx) Crossover Line. This line is for the early '99 through '03, but will work on the 94.5-97 trucks, but you will need to purchase the CNC Fabrication OBS hpop lines due to how the lines are routed on the OBS trucks.
Fittings are the same style as those used on the 94.5-97 powerstroke engines.

A customer conducted a decibel reading and recorded a 4db reduction in engine noise after the installation. The HPx line connects the two heads to help balance the high pressure oil system throughout the circuit.
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 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.
We know it may be cheaper for those wanting to save some money and have a local hydraulic shop make lines, but in our 20yrs experience, it is not advisable due to the amount of thermal cycling and engine sees.
Normal hydraulic is meant for normal hydraulic use, Not on the engines. See pictures of what happens to our competitor lines. Dry rot and blistering of the hose. We have sold over 5000 kits and not one failure due to manufacturing.
Note: If you are unsure of installing this line yourself, seek out a competent and qualified technician to install the lines.
Installation: Disconnect the battery grounds before installation to avoid accidentally arc'ing the line on the glow plug relay or the alternator charging lug. Use the pictures on this page for reference.
After installation, be sure there are no other lines/wires that are touching the lines that could potentially rub through and damage either the hpop line or the other line that may be touching it.
Use a small section of wire loom protector or a larger piece or rubber hose to wrap around the contact point.
Head fittings: 23ft/lbs
