If you have a GMC Acadia and are looking for the gas cap, I have some information for you. The GMC Acadia actually doesn't have a gas cap. Instead, you simply open the fuel door and insert the fuel pump into the gas tank to refuel. To open the gas tank door, first, unlock your vehicle and then head towards the gas tank. Press on the lower left side of the door to open it, and you'll be all set to refuel your vehicle.
To access the gas cap on a 2018 GMC Acadia, push on the outer part of the fuel door to unlock it and unscrew the cap.
