Update. Problem fixed.
Just wanted to update on this issue.
It seemed that the charcoal canister (ventilation) was not the problem in my case.
The problem was with the FUEL FILLER TUBE CHECK VALVE shown as number 4 in the diagram that I have posted above. I got a wire and started pushing it in through the filler tube. At first it got stuck and after several tries it was able to go through and unstuck the valve.
So if it is impossible for you to fill your fuel tank this could be your problem. Impossible I mean when the fuel pump at the gas station keeps shutting of every two seconds even at the slowest gas flow from the fuel pump.
Thank you all for you suggestions and replies above.
