Review on 🔒 ACDelco GT279 Fuel Tank Filler Cap - Genuine GM Original Equipment by Mark Erandio

My car had a P0442 (small evaporator leak) after clearing the code twice the code came back. Further inspection revealed that the fuel cap rubber seal was bad. (big cracks) went to an online shop to replace the gas cap. I found this one and read the reviews. Others claim that the cheaper ones don't fit properly or don't fix the code. So I went and bought this one and my code is fixed. It's the 3rd day now the code won't come back. The gas cap appears to be tightly closed when rotated. My only criticism of this cap is that it's a bit overpriced for a pathetic gas cap.
