The regulated fuel return kit for the 03-07 6.0L Powerstroke Super Duty is an important part of the fuel system upgrade process. This kit Eliminates the "dead-head" stock fuel rails and provides adjustable fuel pressure capability to the Powerstroke fuel system. This is done by tying the end of each fuel rail together through a Bypass Fuel Regulator. The Regulated Return Kit also includes replacement Fuel Feed Lines (from the fuel filter to the cylinder heads) that replace the stock lines and banjo bolts with larger high flow units and eliminates the restrictive check valves.The Primary benefit of the fuel regulated return kit is to SIGNIFICANTLY increase fuel flow "through" the heads, ensuring that each fuel injector has adequate fuel volume and pressure all the time (no more "Wide Open Throttle Pressure Drop"). If you want increased injector life and less injector noise...particularly if you are installing expensive new injectors (larger aftermarket), we HIGHLY RECOMMEND this kit to protect your investment!
