Overview

The Driven Diesel 99-03 7.3L High Pressure Crossover (HPX) is a stainless steel line designed to connect the driver and passenger side High Pressure Oil Rails. This results in a more balanced High Pressure Oil system with fewer pressure spikes, which can lead to smoother operation and a quieter engine. The line is constructed from High Grade MIL-SPEC Stainless Steel tubing and aircraft quality steel fittings for durability.
Show original supplier description
This enhancement helps to reduce high-pressure oil spikes, which can lead to smoother engine operation and potentially a quieter running vehicle. The HPX line is constructed using High Grade MIL-SPEC Stainless Steel tubing and aircraft quality steel fittings, ensuring reliability for thousands of miles. This product is a fully engineered solution, designed using SOLIDWORKS CAD/CAM software and tested with COSMOS (Solidworks Simulation) for stress analysis. It is built to withstand the demanding conditions of the High Pressure Oil System, which operates from 500psi to over 3000psi, including high temperatures, pulsation, and vibration. The Driven Diesel HPX line fits 1999-2003 7.3L Ford Pickups and Excursions equipped with stock or "Drop-In" turbochargers. It does NOT fit with T4 Style turbochargers due to interference with their larger diameter housings.
