There is a rollover valve on top of the tank. Part number MR526922. That vents gasoline vapor from the gas tank and sends it to the evaporative emissions system. The point of the valve is that it will close if the car turns upside-down (preventing liquid gasoline from leaking out the evap system in the engine bay. I'm pretty sure you have to drop the tank to change that one. There is also a check valve clipped to the side of the evap canister. Part number MB925886. That canister and check valve is somewhere in the vicinity of the passenger side of the front bumper. A crack in either valve or a disconnected hose/hard line could result in a gas smell. Figuring out the gas smell should be a priority. It could be a hazard. I expect that you could sniff around and decide if it is coming from the tank area or engine bay. That would help you decide which valve to change first.
