CNC Fab HPOP Line Kit w/ HPx - 1999-2003 Ford F-Series

CNC Fabrication High Pressure Oil Lines w/ HPX Kit – 1999–2003 Ford 7.3L Powerstroke (Super Duty)

Made in the USA

If you’re replacing your HPOP, there’s no better time to upgrade the oil lines and add an HPX crossover for improved system balance and long-term reliability. This complete kit replaces the high-mileage OEM HPOP lines with larger-diameter, high-pressure Aeroquip hoses and adds an HPX line to equalize oil pressure between cylinder heads.

🔥 Key Features:

• Complete Replacement Kit – Includes (2) HPOP lines plus HPX crossover line

• Increased Flow – Upgraded to 3/8" hoses for reduced restriction and improved oil delivery

• HPX Crossover Line – Connects both heads to balance pressure and reduce back-pressure spikes

• Quieter Operation – Many users report reduced idle noise due to minimized Helmholtz resonance

• Aeroquip Hose Construction – DuPont Teflon-lined hoses rated for extreme pressure and temperature

• OEM-Style Fittings – Eliminates factory quick-connect (STC) fittings for improved reliability

📏 Hose & Pressure Specs:

• Burst Pressure: 16,000 PSI

• Working Pressure: 5,000 PSI @ 72°F / 3,000 PSI @ 400°F

• Temperature Rating: Up to 400°F

🔧 Installation Notes:

• Pump Fitting Torque: 28 ft-lbs

• Head Fitting Torque: 23 ft-lbs

• Hose End Torque: 21 ft-lbs

• Remove spring checks in the pump under the stock fittings during installation

✅ Fitment:

• 1999–2003 Ford Super Duty

• 7.3L Powerstroke Diesel

⚠️ Important Info:
The HPX line is designed to balance pressure, not add horsepower. Its benefit comes from reducing pressure spikes that can hammer the HPOP and contribute to noise and wear over time.

Upgrade your high-pressure oil system with the CNC Fabrication HPOP & HPX Kit — a proven solution for durability, smoother operation, and long-term reliability in your Super Duty.
