Maximize performance and efficiency of the fuel system in your 2003-2007 Ford 6.0L Powerstroke with the XDP Regulated Return Fuel System XD206. From the factory, the fuel system in your truck "dead-heads", meaning that fuel cannot leave the fuel rail without going through your injectors. This is known to cause issues such as increased fuel temperatures, trapped air in the system and most importantly the inability to maintain steady pressure across all 8 injectors, especially in high-performance applications. 

The XDP Regulated Return Kit solves this issue by plumbing the fuel rails together through an Aeromotive fuel pressure regulator to create a flow-through design. The fuel pressure regulator also gives you the ability to adjust your fuel pressure which can be measured through the included special edition XDP liquid-filled pressure gauge. Built from only the top quality components, this kit includes braided fuel lines with black anodized fittings, and a stainless steel regulator mounting bracket.  

For an even cleaner install, the XDP Regulated Return Kit has done away with the hard steel lines commonly found in other kits on the market. Our high-quality braided lines are specially designed to eliminate the need for joining multiple lines together. The braided lines are then routed over to the driver side near the coolant reservoir tank where the fuel pressure regulator is neatly mounted on the firewall with our stainless steel no-drill bracket. This kit is great for stock and high performance applications.

  • Increased Performance 
  • Increased Injector Life 
  • Consistent Fuel Pressure
  • Great For High Performance Applications
  • Proudly MADE IN THE USA! 
Application Notes: 
This system bypasses the factory regulator. Upgrades like the "Blue Spring Kit" are unnecessary with the XDP Regulated Return Kit. 
Dual alternator applications may require modifications to the alternator mounting bracket for installation. 
Due to the close proximity of the fuel hose to the EGR Cooler, a heat shield/sleeve is required on trucks with a factory EGR System. A 1/2 x 36" sleeve will cover the vulnerable areas of the hose. (see related items).

I would give this product a 5 star but the mount for the regulator puts the return right above clutch fluid reservoir. Still recommend even if you do have a manual trans...
