Product Description
CNC Fabrication 424005 94.5-03 7.3L Pressure Oil Pump Lines (HPx) Crossover Line
The CNC Fabrication 424005 HPx Crossover Line is designed to improve high-pressure oil system balance on 1994.5-2003 Ford 7.3L Power Stroke engines. Built using genuine Brennan fittings, DuPont Teflon-lined hose, and premium Viton O-rings, the HPx crossover line connects both cylinder heads to help equalize high-pressure oil fluctuations throughout the HEUI injection system.
Unlike standard hydraulic hoses, the CNC Fabrication HPx line is specifically engineered for the demanding thermal cycles and pressure spikes experienced in Power Stroke high-pressure oil systems. With a 16,000 PSI burst pressure rating and 5,000 PSI working pressure rating, this crossover line delivers exceptional durability and reliability. Many owners report reduced engine idle noise after installation as the crossover line helps absorb and balance pressure pulses that would otherwise transfer directly through the HPOP system.

FAQ
What does the HPx crossover line do?
The HPx crossover line connects both cylinder heads to help equalize high-pressure oil fluctuations throughout the HEUI injection system, reducing pressure spikes and improving system balance.
Will the HPx crossover line increase horsepower?
No. The HPx crossover line is not designed to increase horsepower. Its primary purpose is to improve oil system balance and reduce pressure pulse resonance within the high-pressure oil circuit.
Can this reduce engine noise?
Many owners report reduced engine idle noise after installation. One customer documented approximately a 4-decibel reduction due to decreased high-pressure oil system resonance.
Why not use a standard hydraulic hose?
Standard hydraulic hoses are not designed for the extreme thermal cycling and operating environment found on engine-mounted high-pressure oil systems. This can lead to premature deterioration, dry rot, blistering, and failure.
Will this fit OBS and Super Duty trucks?
Yes. The crossover line fits both OBS and Super Duty 7.3L Power Stroke applications. However, OBS trucks require CNC Fabrication OBS HPOP lines due to routing differences.
Are fittings and seals included?
Yes. The CNC Fabrication 424005 includes genuine Brennan fittings and premium Viton O-rings for reliable sealing and long-term durability.
