Product Description
CNC Fabrication 424001 94.5-97 7.3L Replacement High Pressure Oil Pump Lines
The CNC Fabrication 424001 Replacement High Pressure Oil Pump Line Kit is a premium upgrade for 1994.5-1997 Ford 7.3L Power Stroke engines equipped with the HEUI fuel injection system. Designed to replace aging factory HPOP lines, this kit features advanced DuPont Teflon-lined hose construction, genuine Brennan fittings, and high-quality Viton O-rings to provide exceptional durability and reliability under extreme pressure and temperature conditions.
Unlike standard hydraulic hoses that are not designed for constant engine heat and thermal cycling, the CNC Fabrication 424001 utilizes purpose-built materials engineered specifically for high-pressure oil system applications. With a burst pressure rating of 16,000 PSI, operating temperatures up to 400 degrees Fahrenheit, and premium USA-made construction, this kit is an excellent solution for stock, towing, and performance-oriented 7.3L Power Stroke applications.

FAQ
What does the CNC Fabrication 424001 replace?
This kit replaces the factory high-pressure oil pump lines on 1994.5-1997 Ford 7.3L Power Stroke engines equipped with the HEUI fuel injection system.
Does this kit include the crossover hose?
No. The crossover hose shown in some engine photos is not included with the CNC Fabrication 424001 kit.
Why are these lines better than standard hydraulic hoses?
These lines utilize DuPont Teflon-lined hose construction specifically designed for engine-mounted high-pressure oil applications. Standard hydraulic hoses are not designed to withstand the constant heat cycling experienced in diesel engine compartments.
What pressure are the lines rated for?
The lines feature a burst pressure rating of 16,000 PSI with a nominal working pressure of 5,000 PSI at 72°F and 3,000 PSI at 400°F.
Are fittings and seals included?
Yes. The kit includes genuine Brennan fittings and premium Viton O-rings for a complete installation.
Are there any important installation notes?
Yes. Disconnect battery grounds before installation, remove the spring checks beneath the factory HPOP fittings and do not reinstall them, verify routing clearances, and inspect for any potential contact points that could cause hose wear.
What are the fitting torque specifications?
Pump fittings should be torqued to 28 ft-lbs, head fittings to 23 ft-lbs, and hose ends to 21 ft-lbs.
