2003-2007 Powerstroke 6.0L Driven Diesel Standard Regulated Return Fuel System Kit (DD-60FS-STD-RRK-V2)

The Driven Diesel Regulated 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 Pressure Regulator. The Driven Diesel 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 eliminate the restrictive check valves. 

The primary benefit of this kit is SIGNIFICANTLY increased 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 (stock or aftermarket), we HIGHLY RECOMMEND this kit to protect your investment! 

FITMENT NOTE : Driven Diesel 6.0L Regulated Return Kits locate the regulator using a bracket mounted to the alternator. Some Aftermarket/High Amp alternators use a different housing that is not compatible with the Driven Diesel regulator bracket. Modifications to the Driven Diesel regulator bracket, or fabrication of a different mounting bracket, may be required in vehicles with oversized, aftermarket alternators.
