Introduction

The Ford 6.0L Powerstroke Blue Spring fuel pressure regulator upgrade kit restores lost fuel pressure on 2003–2007 Ford F-250, F-350, F-450 and F-550 Super Duty trucks. The factory 6.0 fuel pressure regulator spring wears over time, causing pressure drop, performance issues and injector damage. This complete kit replaces all worn components and includes a replacement orifice for the factory piece that commonly breaks during O-ring replacement.

What Is the Blue Spring Upgrade?

The Blue Spring upgrade replaces the factory fuel pressure regulator spring in the 6.0L Powerstroke with a stiffer, more durable spring that holds correct fuel pressure under load. Low fuel pressure on the 6.0 is a known failure point — it starves injectors and accelerates wear. The Blue Spring kit is the standard fix to restore pressure and protect the fuel system.
