Review on 🔒 Stant 10511Y Yellow Locking Cap for GM Flex-Fuel with Non-Threaded Filler Neck: Secure and Convenient! by Dean Wildfang

This cover fits my 2011 Chevrolet Suburban perfectly! Quality product for the price and works as advertised. The cap has a nice snug fit and the key is comfortable to use. The locking mechanism allows the key to be removed in the unlocked position, eliminating the need to keep the keys attached to the refill cap. Once the cap is off, the lock automatically returns to the closed position, so you don't need to use a key to "relock" the cap, you simply screw it back on. The box contains 2 keys, which is convenient for those who have 2 sets of car keys. Tightening the lid is easy and you will hear a click as the lid locks into place. For vehicles like my Suburban where the fuel filler flap doesn't latch in sync with the passenger doors (and it should, given the vehicle's MSRP of over $50,000), this is a quick and inexpensive solution to preventing unauthorized access or fuel pruning .
