Review on ACDelco GM Original Equipment GT329 Fuel Tank Filler Cap: Reliable and Stylish in Black by Sean Copeland

I did a little research before purchasing and chose this item because the tether and matching chart said it would work with our GMC Acadia. It did not work. The band worked well and the lid screwed in but did not cover the container. The tank seal is very important. My wife was concerned when her engine light came on and Onstar informed her that there was an evaporative emissions issue and recommended checking the gas cap. I have reset the error code multiple times and made a valid attempt to do so. cap work. It wouldn't close no matter what I did. I ended up having to break the strap holding the new cap in order to remove it and replace it with an old OEM strapless cap. Reason for purchase was the strap on the OEM cap broke but the cap worked fine. Believe it or not, the lack of a fastening strap really annoys me. Buying from Revain is easy, but this time I wasn't satisfied and I realize I can't rely on the aftermarket for everything.
