The Ford F-350 Fuel Pressure Regulator by Sinister Diesel, specifically the Blue Spring Cap Kit in Sinister Blue, is a precision-designed upgrade for 2003-2007 models. This essential component brings your fuel system back to its ideal factory pressure, ensuring optimal performance and longevity for your truck.

With this kit, most 6.0-liter Powerstroke engines experience an increase of around 10 psi in fuel pressure. This heightened pressure allows injectors to operate more efficiently, reducing the risk of air getting trapped and, thus, extending the lifespan of your injectors. The kit includes all necessary O-rings and parts to rebuild the fuel pressure housing, along with a robust billet aluminum spring housing that prevents fuel leakage common in the original cast aluminum parts. Noteworthy is the adjuster screw feature, which lets you fine-tune the pressure, especially beneficial for setups with larger injectors or as the spring settles over time. This can lead to smoother idling, quicker throttle response, and enhanced turbo performance.
