Increase the fuel pressure on your 6.0 Powerstroke using this Ford OEM updated part.
Ford discovered that under heavy load and acceleration, fuel pressure would begin to drop below 45psi. When fuel pressure drops below 45psi on your 6.0 Powerstroke, damage to the injectors can start to occur. Fords developed a solution that includes a stiffer regulator spring, increasing fuel pressure and preventing it from dropping below 45psi.
Kit includes all hardware and seals needed to install.
Commonly referred to as the "blue spring mod".
Very simple yet effective upgrade/update for any 6.0 Powerstroke!
