smell gas on the rear left side of the wheel
 

I checked the 2 hoses and connections next to the fill cap area and they are all secured. There is a strong smell of gas around the left rear wheel. I don't know what causes that. Need help. thanks

the EVAP system has a charcoal canister and a purge valve that prevents fuel vapors from escaping the tank by storing the fumes in the charcoal canister then letting the purge valve purge the fumes into the engine at the correct time to burn off.
perhaps, the purge valve or charcoal canister is starting to fail.

where is the the purge valve or charcoal canister ? Thanks

It does not show any engine light. Can this still be EVAP canister? thanks
