This item is MADE TO ORDER. Expect longer than normal ship times on this kit.
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 "Bowl Delete" 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 Delete" Regulated Return kit also eliminates the restrictive fuel filter bowl, improving fuel flow to the heads and giving back some valuable engine valley room.
NOTE: Additional Parts and Filtration Required when using this kit. If using a stock fuel pump, you will need one of our "Post-Pump Fuel Filter Kits" AND the "5/16" Quick Disconnect Adapter Fitting". Part # 644113 is included with kit. The Post-Pump fuel filter kits will also work if using a Fuelab or Aeromotive "race" style fuel pump (you just don't need the adapter fitting). You can also use a High Pressure AirDog or FASS type product, as long as you make sure it's capable of making roughly 75psi of pressure at the pump.
The primary benefits of this kit are significantly increased fuel flow "through" the heads, eliminating starvation of the #8 cylinder and 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 one of our Regulated Return kits to protect your investment and maximize your performance!

NOTE: WITH THE EXCEPTION OF ITEMS LISTED IN THE FUEL SYSTEM COMPONENTS SECTION OF OUR WEBSITE, WE DO NOT SELL INDIVIDUAL PIECES OF OUR FUEL SYSTEMS.
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.
MADE IN THE USA! We take this very seriously, and we try to use as much U.S. made material and product as we possibly can in the assembly of our fuel system kits. ALL of the custom machining, anodize, engraving, cutting, bending and hose assembly is done in the U.S., by American workers. The Fuelab pressure regulator and all of the S.S. braided hose are also U.S. made products.
