These are made to order and may result in longer then normal delayed shipping times.
Note from the manufacture: Please be aware that we DO NOT have a CARB EO# for our fuel system kits, and as of right now we do NOT have any plans to pursue one. Sales of ANY of our fuel system kits into California (or any other state that uses the CARB system) will result in a customer’s vehicle possibly failing the visual emissions inspection.
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 check valves.
The primary benefits of this kit are significantly increased fuel flow "through" the heads, ensuring that each fuel injector has adequate fuel quantity and pressure all the time. Additionally, any air "bubbles" that may develop in the fuel system can pass through the heads and out the regulators return port to the tank, instead of through the fuel injectors...resulting in increased injector life and less injector noise. If you are installing new injectors (stock or aftermarket), we HIGHLY RECOMMEND this kit to protect your investment!
