Fit correctly and easy install 👍👍

Easy to attach and satisfying to hear that click after a fill up.
Someone tried to break the old gas cap by destroying the key lock, so went back with the original cap and connected the strap to the vehicle. Worth the price, nice and clean!

Great replacement
My OEM gas cap for my '99 Chevrolet Silverado 1500 has started freezing in the winter months, allowing pressure to build up in the tank which ultimately throws a code. I assume the materials are just aging as it is the original cap that came with the truck. I purchased an off-brand locking gas cap and it wouldn't release vapors either, allowing pressure to build up and throwing a code. Everything else checked out so I purchased the AC Delco gas cap, problem solved. I trust AC Delco and have never had any issues with AC Delco (GM Genuine) parts and would recommend this gas cap.

Didn't fix my EVAP code but is a good place to start!
I was getting a P0443 code on my 2006 Silverado, so I did what others said online and replaced the gas cap first. It's an easy first step and can fix some EVAP codes, but not in my case. Still, I can't take off any stars because it's a great OEM-quality replacement and was a good value; it just didn't fix my problem. I definitely recommend this as a first step to fixing EVAP issues!
