Description
Restore proper fuel pressure and improve injector performance on your 2003–2007 Ford 6.0L Powerstroke with this OEM Ford Blue Spring Kit (Part #3C3Z-9T517-AG). This is the updated factory solution to common low-fuel-pressure issues that can lead to premature injector failure, hard starts, poor throttle response, and sluggish turbo spool.
This kit includes the upgraded blue spring, all required seals, hardware, and the cover, offering a complete bolt-on solution for aging fuel pressure regulator assemblies.
Why Upgrade to the Blue Spring Kit?
- Restores factory fuel pressure (gain of 8–10 PSI common)
- Prevents injector overrun and starvation
- Smoother idle and improved throttle response
- Reduces air in the fuel system
