The Driven Diesel Regulated Return Kit for the 99-03 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 accomplished 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 eliminate the stock Check Valves and the "kinks and crimps" of the stock feed lines.

The primary benefits of this kit are significantly increased fuel flow "through" the heads, eliminating fuel delivery and noise issues associated with the #8 injector and 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!

BIO-DIESEL NOTE: While we've taken steps to significantly improve the bio-diesel compatibilty of our fuel system kits, we still recommend bio concentrations of B20 or less. Higher concentrations can negatively impact the glues used to assemble most fuel filter elements.

* - We make every attempt possible to source and use as much U.S. made product/material as we possibly long as doing so doesn't sacrifice the quality of the final product. We can't always control where every component of one of our products comes from, but you count on us to keep looking for ways to increase the % of American Made parts and materials in the products that we produce.
