Description: This high - quality Blue Spring Kit is a game - changer for your 2003 - 2007 Ford F - 250, F - 350, and Excursion with a 6.0 engine. It's a quick 30 - minute install that boosts fuel pressure to factory levels. Most 6.0 engines see a 10 psi increase. This extra pressure prevents injectors from overpowering the stock fuel pump, reducing air in injectors and extending their lifespan. At idle, your truck will run quieter, rev up faster, and the turbo will spool up quicker. The kit's block has an adjuster screw. You can increase pressure for big injectors or adjust it after years of use. We recommend setting the fuel pressure between 55 - 68 psi. It comes with a brand - new billet aluminum housing that's thicker and stronger than the factory one, preventing fuel leaks. Features include CNC - machined T6 - 6061 billet aluminum, a laser - etched Sinister Diesel logo, a new 'Blue Spring', new gaskets, and more. Note: Not compatible with E - series Powerstrokes. Part Number: SDG - 6.0P - FBADJ - 03 - 01 - 20

Using this Blue Spring Kit is easy. First, make sure your vehicle is turned off and cooled down. The installation process should take about 30 minutes. Just replace the old parts with the new ones from the kit. When you're done, start your truck and check for any fuel leaks. For the adjuster screw, if you have big injectors or after years of use, you can increase the fuel pressure. Loosen the jam nut and turn the adjuster screw in a turn or two. We suggest setting the fuel pressure between 55 - 68 psi. As for maintenance, regularly check the billet aluminum housing for any signs of wear or leaks. If you notice any issues with the fuel pressure or your truck's performance, it might be time to readjust the screw. Remember, this kit is not compatible with E - series Powerstrokes, so don't try to use it on those models.
