This Blue Spring Kit is specifically designed for 2003 - 2007 Ford Super Duty F - 250/F - 350/F - 450/F - 50 trucks with a 3.0L Powerstroke engine. Part number is 3C3Z - 9T517 - AG. Installing this new updated Ford 'Blue Spring' is a breeze, taking just 30 minutes. It can boost your fuel pressure back to the factory - recommended level. Most 6.0 - liter engines will see a 10 - psi increase in fuel pressure. The extra fuel pressure prevents injectors from out - flowing the stock fuel pump, eliminating air in the injectors and extending their lifespan. At idle, your truck will run quieter, rev up faster, and the turbo will spool up quicker. The kit comes with all O - Rings and hard parts needed to rebuild the fuel pressure housing.

Using this Blue Spring Kit is easy. First, make sure your truck's engine is off and cooled down. Locate the fuel pressure housing. Then, carefully remove the old parts and install the new Blue Spring and the included O - Rings and hard parts according to the standard procedures. It should take about 30 minutes to complete the installation. As for maintenance, it's a good idea to check the fuel pressure regularly to ensure the kit is working properly. Also, keep an eye on the O - Rings for any signs of wear or damage. If you notice any issues like a drop in fuel pressure or strange noises from the engine, it might be time to have the kit inspected or replaced. Remember, this kit is only suitable for 2003 - 2007 Ford Super Duty trucks with a 3.0L Powerstroke engine, so don't try to use it on other models.
