The No Limit Tuning & Design Super Duty Full Fuel System is a full regulated return aftermarket fuel system for a 1999 - 2003 Super Duty 7.3L Powerstroke. This system is designed to replace the entire factory fuel system including the pump, fuel bowl, lines, etc. With sleek, black, braided lines and performance fittings, this kit will improve the look AND performance of your 7.3L engine.
Why do I need a full fuel system?
Fuel pressure is critical to a 7.3L Powerstroke, particularly when aftermarket injectors or in performance applications. This kit has been dyno proven on 600-650hp trucks and would support a more demanding setup. This full fuel system offers a high output Walbro fuel pump and a Phenix Industries adjustable regulator so maintaining the required 65psi is not a problem. If the fuel pressure is low or dropping, particularly in an aftermarket application, not only will you loose horsepower and mileage, you are risking damage to the injectors.
What does this kit include?
With dual feed line and return lines, this full fuel system is much more efficient than the restrictive factory design. The frame-mounted filtration system is offered with or without clear sediment bowls for easy access and visibility to your engines fuel supply.* The Walbro fuel pump and Phenix Industries adjustable regulator are monitored through liquid filled 100psi Titan gauge. A fuel sump is included for maximum benefit and efficiency.
What will I need to install this kit?
See the installation guide for complete details. This kit is a 6-8 hour installation job and should be installed by someone with mechanical experience.
* If you have a lowered or off road vehicle, we may not suggest the option of clear sediment bowls
