Review on Motorad MGC 791 Locking Fuel Cap by Esera Warren

For 2014 Toyota Tundra. I don't write many reviews but I have to for this one. This lid does not close when closed. Whatever you do, tighten the lid until it clicks 3 or 50 times, once you turn the key to lock the lid it will loosen and cause evaporation. Check engine light leak. If you fiddle with it a few times you might get lucky and it will be tight, but that's only until the next fill. I'm an auto technician and I know what I'm doing, I've been trying this cap for 3 months and it won't close almost every time I fill up and it keeps trying to tighten it, turn the latch, check the lock and hope it is tight but a day later the Check Engine light comes on.
