Wow. Is that burnt make by the gas cap?
Any way, in the future (for new posting) go under Mitsubishi Proton. And as you write your description, identify Saga 1.3L Magma as your engine. I used to play around with that engine years and years ago. Fume smell can only come from your EVAP system malfunction or leaky fuel system (which I consider part of EVAP system). Here is a typical EVAP system. If you have a leak at any point from the gas cap all the way to the carburator and back to the gas tank via the fuel return hose, you will smell the fume.
The fume you smell close to the filler hose is probably from the black mark close to the gas cap, or possibly a leak in the filler hose going to the gas tank. You still may have a problem with either the charcoal canister or the purge valve (run off vacuum), creating fume in the return line causing the smell to creep up the gas filler hose.
