fuel smell from rear left wheel

there is a charcoal canister if i recall correctly at the rear left wheel and the fact is that i can smell fuel from this area. i noticed it today. it was first relatively warm day in this year. i assume pressure in the reservoir was relatively high and fuel fumes escaped out but i doubt it should be so. there is no noticeable leaking of the fuel anywhere in the car. the smell comes only from one source ... maybe another source is when i open the trunk and i can smell fuel, too.

did anybody have the same problem and what the problem actually is? broken line from/to fuel reservoir or something like that? maybe broken charcoal canister?

I'd think that somewhere between the filler neck and tank is a leak from a hose. Especially when you don't see any gas leaking on the ground. The only way to be sure is pulling it apart. Hopefully it's something that can be fixed quickly.

But my filler neck is on the right side. why the smell does not come from there then? anyway, thanks for your hint but i am afraid it is a big job to check it.

Oh no!!! I hadn't realized this my friend. I'm sorry. There has to be something not so hard to diagnose the fuel vapor leak.

is silicone good to fix cracks in plastics

i am waiting to get my EPC&WIS DVDs from England, then I will check if charcoal canister is broken. In case it is, I guess i can fix it.

Will epoxy glue or silicone sealer work?

That plastic looks pretty tough. I'd use a epoxy plastic welding product if it were broken. Hopefully it's just a hose.
