Review on 🔒 ACDelco GM GT231 Fuel Tank Filler Cap, Black - Original Equipment by Jason Carranza

My check engine light came on. I checked it out at Autozone and they told me it was the gas cap. Well, I already knew I didn't even have a gas cap (I didn't realize the Check Engine line would light up due to the lack of a gas cap). So I bought this. The leash snaps into place and the cap fits perfectly. I've read to make sure you tighten it and keep turning it until you hear a few clicks and the sensor turns the check engine light off. So I did and now my check engine light is off! Great product that did exactly what I needed.
