The Sinister Diesel Blue Spring Kit with adjustable billet spring housing and fuel filter cap is specified for 2003–2007 Ford 6.0L Powerstroke engines to restore lost fuel pressure and allow fine tuning. Many 6.0L trucks see roughly a 10 psi rise in fuel pressure after installation. The kit includes an anodized blue T6‑6061 billet housing and fuel filter cap with a 1/8" NPT test port, new spring and gasket set, and hardware; the adjustable design lets you set pressure within the recommended 55–68 psi range.
