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

Revainrating 5 out of 5

Best money I've ever spent on a My Ford 6.0 Diesel Engine

I checked fuel economy on 4 fuel tanks, weekly usage of 35 gallons per week and after installing the upgrade kit showed an average improvement from 2.8 mpg. .
