The Driven Diesel Regulated Return Kit for the 03-07 6.0L Powerstroke Super Duty takes our popular "Standard" Regulated Return Kit to a new level. Just like our "Standard" version, this kit eliminates the "dead-head" stock fuel rails and provides adjustable fuel pressure capability to the Powerstroke fuel system. This is accomplished by tying the end of each fuel rail together through a Bypass Fuel Pressure Regulator. In addition, the  Regulated Return kit also eliminates the restrictive stock fuel filter bowl, improving fuel flow to the heads and giving back some valuable engine valley room...particularly if you are also deleting the factory oil filter bowl by using a Bullet Proof Diesel oil cooler kit (or similar).

The primary benefits of this kit are significantly increased fuel flow "through" the heads, ensuring that every fuel injector has adequate fuel quantity and pressure all the time. Additionally, any air 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 one of our Regulated Return kits to protect your investment and maximize your performance!

The most commonly reported results from the installation of an Driven Diesel Regulated Return Kit are: 

• Improved Throttle Response 
• Increased Power Output
