Product Name: CNC Fabrication High Pressure Oil Pump Lines w/ HPx KIT - 94.5-97 Ford 7.3L Manufacturer: CNC Fabrication Manufacturer Part #: 424002 Thoroughbred Diesel Part #: CNC424002 Fitment Notes: 1994.5-1997 Ford Powerstroke 7.3L
94-97 Ford Powerstroke 7.3L Replacement High Pressure Oil Pump Lines. Replace your high-mileage (and expensive) OEM High Pressure Oil Pump lines with a CNC Fabrication upgrade!
The HPx line connects the two heads to help balance the high pressure oil system in each head. It does not create more horsepower, but the majority of owners see a slight to significant decrease in engine idle noise.
This is due to the Helmholtz resonance 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.
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. The lines are marked PA for passenger head and DR for driver head.
After installation, be sure there is 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.
Although it is not necessary as there is room on the driver side, but the eyelet for engine removal may need to be slightly bent in using a large pry-bar through the eyelet hole bending it towards the fuel bowl. Do not use any thread sealant on any of the fittings, except on the pump.
If you choose to use any, use Loctite 680 or 620 retaining compound (green), but it is not necessary.
These lines will route different than OEM. Driver side will route just like the 99-03 models. Which means it will now route to the second oil galley port and go around the engine lifting eyelet. The passenger side line will arch slightly over the front fuel bowl lid.
This will not hinder the removal of the fuel filter. The HPx line will route just like the 99-03 trucks also (which is the third set of oil galley ports back starting from the front of the vehicle) picture of the lines installed will be coming.
If you are unsure of installing yourself, seek out a competent and qualified technician to install the lines.

Notice:
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 10,000 kits.
