Product Name: CNC Fabrication Replacement High Pressure Oil Pump Lines - Early 99-03 Ford 7.3L Manufacturer: CNC Fabrication Manufacturer Part #: 424003 Thoroughbred Diesel Part #: CNC424003 Fitment Notes: Early 1999-2003 Ford Powerstroke 7.3L
Early 99-03 Ford Powerstroke 7.3L Replacement High Pressure Oil Pump Lines. Replace your high-mileage (and expensive) OEM High Pressure Oil Pump lines with the Number 1 selling CNC Fabrication upgraded HPOP lines!
These lines are to replace the typical high mileage expensive leaky OEM HPOP lines that have the STC fittings. Kit comes with 2 hoses and all necessary fittings to eliminate the quick connect fittings (STC) on the heads and the HPOP 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 prybar 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. If you are unsure of installing yourself, seek out a competent and qualified technician to install the lines.

CNC Fabrication Replacement High Pressure Oil Pump Lines Features:
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.
Not required with the new lines and fitting’s
