Review on 🚀 6.0 Powerstroke Blue Spring Kit Upgrade for F250, F350, F450, F550 (2003-2007) - Replaces # 3C3Z-9T517-AG 3C3Z9T517AG by Mark Walsh

Typical of this cheap product. The metal body is useless because the nipple coming out of the old fuel line body does not screw into it. You basically buy it for everything else. Simply reuse the metal case you took off the truck and replace all the o-rings, gaskets and springs with this one. Also, the screws provided are not the best and are a larger size than T25 compared to standard T27 screws. Which was good for me because I didn't have a T27. ha ha. If you want a complete replacement for ALL, opt for the more expensive Ford OEM or Sinister Diesel.
