Ford OEM Fuel Pressure Regulator Blue Spring Upgrade 03-07 6.0L

This is the least expensive upgrade you'll find for the 6.0L's that will actually make a considerable difference. The "Blue Spring" Upgrade Kit is a 100% OEM kit from Ford that takes roughly 30 minutes to install and will increase your fuel pressure by roughly 10 PSI. This added pressure will ensure that your pump is properly matched in flow to your injectors, giving them a longer life span. Because of a more consistent pressure, you will also notice a slight increase in responsiveness of the truck, as well. This kit includes all of the necessary parts for a complete installation.
