Driven Diesel 7.3 OBS High Pressure Oil Crossover Pipe (HPX) | 1994-1997 Ford Powerstroke 7.3L OBS

The Driven Diesel Stainless Steel High Pressure Crossover (HPX) line connects the driver side and passenger side High Pressure Oil Rails together. This results in a more balanced High Pressure Oil system with fewer pressure spikes (see Injection Control Pressure graphs below). In most trucks, the elimination of ICP spikes and balancing of pressures in the High Pressure Oil Rails will smooth operation and may even quiet the engine somewhat.

This line fits 94-97 7.3L Pickups with Stock or "Drop-In" turbochargers. Does NOT fit with T4 Style turbochargers due to interferance with the larger diameter housings. You will NOT find a better HPX line ANYWHERE...PERIOD!!! The Driven Diesel HPX line is constructed from only the highest quality components. High Grade MIL-SPEC Stainless Steel tubing and aircraft quality steel fittings ensure thousands of miles of trouble-free operation. BEFORE YOU ASK...YES, this is the same HPX line that was sold under the "KCM Diesel" brand for many years. The owner of KCM Diesel has backed away from doing vehicle work, but he still produces these HPX lines for us, so we can continue to offer our customers a superior product.

Special Note

The High Pressure Oil System operates from 500psi to over 3000psi. Components of this system must be designed to handle these pressures on a CONTINUOUS basis. In addition to pressure, the high temperatures of the engine oil and underhood environment, high pulsation rate of the high pressure oil system and the general expansion, contraction and vibration of a running Powerstroke make for a tough operating environment. The proper design of a High Pressure Crossover line is far more than just picking some hose with a high enough pressure rating and having some fittings crimped on or bending up a tube and attaching it to the engine! Make sure the HPX line you purchase is an ENGINEERED SOLUTION and not just a "slapped together" hose or tube!

The Driven Diesel S.S. HPX line IS an Engineered Solution, not just a hydraulic hose or randomly bent piece of tubing. The Driven Diesel HPX line is produced for us by KCM. Chris Kersey of KCM has a degree in Manufacturing Engineering with a minor in Metallurgy. He has extensive experience designing and manufacturing MISSION CRITICAL weapons components for the military, both of which were used when designing this HPX line.
