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

Chevy Silverado LS 2003. If the check engine light came on, it meant a leak. Drop it to see it. Engine light came back 2 days later. Bought this hat and the light went out by itself. Exactly the same hat as mine. Had to use some scissors and cut a bit sharp to get the old one out but the new one went right in. 5/5 all day.
