Detailed Review
The E-cowlboy High Pressure Oil Pump HPOP Hose Kit is a direct replacement set designed for 1999 to 2003 Ford 7.3L Powerstroke diesel vehicles. It addresses the common failure point of factory snap-to-connect style fittings by swapping them out for threaded, zinc-plated forged steel hardware. This setup helps prevent high-pressure oil leaks while maintaining consistent fluid distribution across both cylinder heads.
Built with a multi-layer structure, the hoses are engineered to handle rugged engine environments. They support a working pressure of 5,800 psi and a minimum burst pressure of 23,200 psi. In addition, the lines are rated for temperatures ranging from -50°F to over 260°F, which easily accommodates standard operating conditions where engine oil temperatures should remain below 225°F.
A central feature of this complete three-hose kit is the included crossover line. By bridging the oil supply, the system equalizes pressure continuously, leading to smoother engine idling in cold conditions as well as steadier running at highway speeds. The kit is engineered to meet or exceed OEM performance requirements and replaces part numbers YC3Z-9J323-E, YC3Z-9J323-F, and F81Z-9J323-E.
As a specialized mechanical upgrade, compatibility is strictly limited to 7.3L Ford diesel trucks, vans, and SUVs from the specified model years. Buyers looking for lines for other diesel displacements or different engine configurations will not be able to use this kit.
Verdict: This hose kit is a solid choice for owners of 1999 to 2003 Ford 7.3L Powerstroke vehicles looking to eliminate leaky factory snap fittings and stabilize high-pressure oil delivery. It provides a complete three-hose solution built with heavy-duty pressure ratings and corrosion-resistant steel fittings.

Who Should Buy It
A great fit if you:
- Drive a 1999-2003 Ford F-250, F-350, F-450, F-550, F-650, or F-750 with a 7.3L diesel.
- Own a 1999-up E-350, E-450, E-550, or Excursion powered by the 7.3L engine.
- Want to eliminate worn factory snap-to-connect oil fittings that are prone to leaking.
- Experience rough cold-weather idling or want smoother operation at highway speeds.
Consider something else if you:
- Have a Ford diesel truck with an engine displacement other than the 7.3L Powerstroke.
- Only need a single replacement line rather than a full three-hose crossover system.
