Driven Diesel 7.3 Regulated Return kit (retains stock bowl)
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.

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.

Driven Diesel 7.3L Fuel Tank / Pre-Pump Kit
The Driven Diesel Fuel Tank / Pre-Pump Kit is the first step in the fuel system upgrade process. This kit includes all of the parts necessary to eliminate "air leaks" in the fuel circuit before the electric fuel pump (suction side) and add additional fuel filtration. Air in diesel fuel causes noisy operation and can damage the fuel injectors. This kit fits both the Super Duty Trucks and Excursions.
