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 99-03 7.3L Pickups and Excursions with Stock or "Drop-In" turbochargers. Does NOT fit with T4 Style turbochargers due to interfance 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.

IMPORTANT NOTE - PLEASE READ:

 

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 temparatures 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 Metalurgy. He has extensive experience designing and manufacturing MISSION CRITICAL weapons components for the military, both of which were used when designing this HPX line...see below for details:

•Designed by an ENGINEER
•Designed using SOLIDWORKS CAD/CAM Software
•"Stress Analysis" Tested using COSMOS (Now Solidworks Simulation) Software
•Tested for THOUSANDS OF MILES before ever offered for Sale
•Manufactured using High Grade MIL-SPEC S.S. Tubing and Fittings
•THOUSANDS of units in operation Without a Single Design Related Failure!

If you're comparing this HPX line to those offered by our competitors at a lower price, and wondering why this line is more expensive, now you know!

Great product with great instructions. It is a perfect fit so it took a little patience to get the tube to slide in the driver's side once the tube was in the passenger's side "boss".

I was skeptical even after reading all the positive reviews. IT WORKS! My results: Noticably quieter, and smoother. I even had an occasional passenger ride with me and mention how much smoother and quieter the truck was. He had no idea I had done anything, he came up with that comment without any prompting. Worth twice the price.

Superior quality. Very professional packaging. Install fairly easy and definitely felt improvement in engine performance. By far one of the better online transactions I have had from all the diesel sites I have purchased from. Also, thanks for the SD stickers, badass..
