The XDP Billet Adjustable Fuel Pressure Regulator "Blue Spring" Kit XD370 combines two essential modifications that increase the fuel pressure on your 2003-2007 Ford 6.0L Powerstroke. The "Blue Spring" Upgrade is the first step, a direct-replacement for the factory springs in your fuel pressure regulator. The "Blue Spring" adds around 10 PSI of a fuel pressure increase and is the perfect upgrade to enhance performance and driveability on any stock or modified pickup. 

Once the "Blue Spring" is installed most owners see "around" 10 PSI. This is where the XDP Billet Adjustable Fuel Pressure Regulator shines. While the "Blue Spring" gets you in the ballpark, it might not give you the exact pressure you're looking for. The XDP Billet Regulator Housing eliminates this issue by allowing for precise adjustments. All you need to do is loosen the jam nut and adjust the regulator screw to you reach your desired pressure. Each Fuel Pressure Regulator is CNC-machined from billet aluminum and features a black anodized finish for durability, strength, and an enhanced appearance. This kit is great for use on stock and modified trucks.

  • Provide Fuel Pressure Increase
  • "Blue Spring" Kit & Billet Adjustable Regulator
  • Allows For Precise Fuel Pressure Adjustment
  • Black Anodized Finish & Billet Construction For Enhanced Underhood Appearance
Application Note: 
The XD369 Billet Regulator Housing does not come "pre-set". You must install it and then adjust your pressure.
The XDP 6.0L Billet Fuel Filter Cap XD266 is a great add-on for this product as it provides an easy "no-drill" location to obtain fuel pressure with a gauge of your choice (sold separately).
