Fuel smell from near the charcoal canister tank on a hot day

Hi the best community in the world,
I have a 2009 Suzuki Jimny at about 144.000km. Today was a really hot day (41 degrees) and the A/C was open. After the heavy traffic, I noticed the smell of gasoline inside the vehicle. When I opened the hood and checked, I found that the smell was coming from near this tank. No steam or leaks were visible but there is a serious fuel smell both inside the vehicle and near this tank. Also there is a pressure inside the fuel tank.
What may be the problem? What should I check?

Err it could be a blocked breather to the fuel tank? Not had this personally. Thing is fuel vapour has to come from somewhere so check all the joints and pipes for good condition.
 

First of all, thanks Lambert.
But when I get close to the tank, the smell is very intense. Is there a fault in the solenoid valve of the tank?
By the way, where exactly are the fuel pipes?
