Review on 🔒 Motorcraft- High-Performance FC935 Fuel Cap for Enhanced Engine Efficiency by Joe Jordan

Installed, Driven, Check Engine Light came on along with Large Leak Detect Code. Before, I lived with a small vaporizer leak detection code. Reset code, put lid back on, same thing. many times. I then bought a cheap generic Napa cap, reset the code and the check engine light was back on but a little vaporizer detection like my original cap. I originally bought this Motorcraft OEM part thinking it might take care of finding a little leak code, but that only made things worse. This cap has the same key as the 2006 F5.4L 250 engine.
