Review on ACDelco GT294 Yellow Fuel Tank Cap for GM Original Equipment: A Reliable Solution by Francis Heart

OEM Original. This is a genuine ACDelco part at a great price. I was skeptical of how cheap it is, but it arrived in the original ACDelco packaging. Fits my 2009 Impala 3.5L V6 Flex exactly (Vin Code K). Fits tight. I see that others have noticed that it fits loosely. I have not experienced this. Note this for the flex fuel version (VIN: K&M), if you do not have the flex fuel version you will need part number GT283 (VIN code N and C).
