Review on 💪 Enhance Performance with 6.0 Blue Spring Kit Upgrade for Ford Trucks - F250, F350, F450, F550 2003-2007 - Replace 3C3Z-9T517-AG by Wayne Ohlrogge

All I bought this for was the spring. Spring seems harder. Some of the o-rings in the kit didn't fit so I had to use my old ones. It would be nice to be able to replace the o-rings with new ones to provide more durable and new seals. You guys who put this build together really need to solve the problem that a lot of people had when buying this kit and getting the right size o-rings to fit in. I also used my old metal case because what came with the kit had metal burrs that weren't properly cleaned, so I didn't want to risk metal shavings getting into my fuel system. Along with this is a thread that we didn't get right so I couldn't even screw the fuel line in. Again, I only bought it for spring, but seriously, if you're going to provide a kit, at least provide good parts and good o-rings and gaskets.
