Review on Enhanced Fuel Pressure Regulator Spring Kit for 2003-2007 F250, F350, F450, F550 - OE Part # 3C3Z9T517AG Replacement by Steve Snyder

Revainrating 5 out of 5

Good set of blue springs at an affordable price.

Easy installation. Fits exactly as it should. The injectors fire much better with the extra pressure on my 03 6.0l engine.

Pros
  • Fuel system
Cons
  • Small things
