The fuel pressure regulator kit upgrade is a must-have modification that will increase fuel pressure on your 03-07 6.0L Powerstroke. Even simple aftermarket performance upgrades can easily challenge the limits of your stock fuel system. Increasing the fuel pressure will help prevent damage to your injectors and even extend injector life. Common pressure increases can be 10-15 PSI as well as increased engine performance, increased driveability and smoother power delivery.
