I can small fuel around my car,, i had a look at it the other day and it looked damp around where the tank is joined, I patched it up but Im not sure if there could be a vapour leak somewhere else?? has anyone else had this problem??

At the back of the bulkhead there is a small pipe that sometimes comes a part
and you can smell fuel you will need a light to see
as its dark down there.Its on the left side if you were sitting in driver seat
the pipe go to the carbone filter did this on mine
