Standard Regulated Return Fuel System Kit

The Driven Diesel Standard Regulated Return Fuel System Kit is engineered to enhance the fuel system of 1999-2003 Ford 7.3L Powerstroke Super Duty trucks. This comprehensive kit replaces the restrictive stock fuel rails and introduces adjustable fuel pressure control. By linking the ends of the fuel rails and incorporating a Bypass Fuel Pressure Regulator, the system ensures consistent fuel delivery. It also features upgraded Fuel Feed Lines that eliminate restrictive stock check valves and improve flow dynamics from the fuel filter to the cylinder heads. The primary advantages of this regulated return system are a substantial increase in fuel flow directed through the cylinder heads. This addresses common issues such as inconsistent fuel delivery and noise problems, particularly affecting the #8 injector. The system guarantees that every fuel injector receives sufficient fuel quantity and stable pressure at all times. Furthermore, the design allows any air that may accumulate in the fuel system to be efficiently vented through the regulator's return port to the tank, bypassing the injectors. This not only extends injector life but also reduces injector noise. For owners planning to install new injectors, whether stock or aftermarket, Driven Diesel highly recommends this Regulated Return Kit. It serves as a crucial investment protection measure and is key to maximizing the performance potential of upgraded injectors. An optional High Flow Banjo Bolt Kit is available, replacing the stock restrictive banjo bolts with Driven Diesel's T-304 stainless steel bolts. These bolts feature larger internal passages, reducing restriction and increasing fuel flow to the rails. This leads to less fuel turbulence and better support for higher horsepower modifications and larger injectors. FITMENT NOTE: This kit will NOT fit the E-Series Van.
