3mirrors High Pressure Oil Pump HPOP Hoses Lines & Crossover Replacement Kit

The 3mirrors High Pressure Oil Pump HPOP Hoses Lines and Crossover Replacement Kit is designed specifically for 1999 to 2003 Ford 7.3L Powerstroke turbocharged diesel engines. It replaces factory high-pressure oil lines, giving truck owners a dedicated setup tailored to handle the heavy hydraulic demands of these specific powerplants.

Built from Eaton GH781-06 dual metal braided hose, this kit offers 3/8-inch inside diameter lines featuring multi-layered protection. It delivers an operational working pressure of 400 Bar (5,800 PSI) and a burst pressure rating of 1,600 Bar (23,200 PSI). Combined with JIC37 connections and Viton O-rings, the hoses are built to maintain structural integrity across temperatures from -50 to +259 degrees Fahrenheit.

The engineering focuses on clean installation and fluid security. An elbow pipe-end design uses minimal joints across the run, which speeds up the installation process and reduces common leak locations. The durable braided material and Viton seals provide over five years of steady use under harsh engine bay conditions.

Because this kit is engineered exclusively for 1999-2003 Ford Super Duty trucks and 1999-up E-series vans with the 7.3L diesel engine, it is not suitable for earlier 7.3L models or other engine platforms. The listing focuses on primary line hardware, so buyers should confirm their existing engine bay setup matches these exact specifications before beginning the swap.

Verdict: This high-pressure hose kit is a solid choice for owners of 1999-2003 7.3L Powerstroke vehicles needing durable, direct-fit replacement oil lines. Its dual metal braided build and 5,800 PSI rating provide dependable performance under extreme engine heat and pressure.
