1999-2003 Powerstroke 7.3L Driven Diesel Fuel Bowl Regulated Return (DD-73FS-FBD-RRK-V3)

The Driven Diesel " Fuel Bowl " Regulated Return Kit for the 99-03 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 "Bowl " Regulated Return kit also eliminates the restrictive fuel filter bowl, improving fuel flow to the heads and giving back some valuable engine valley room.

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!

If your OEM metal fuel return line along your frame is damaged, rusted or leaking, and you want/need to replace it, see the PRODUCT OPTIONS section for the REPLACEMENT RETURN HOSE upgrade. This upgrade will provide you with enough 5/16" fuel line to run a fresh connection from the bottom of our fuel pressure regulator all the way back to your fuel tank.
