    If you can't smell or see fuel leaking and the car is running fine, I wouldn't worry about it.

    Might be from the pressure gradually bleeding off and it just happens to make a little noise at the fuel filter. One of the lines right around there is the fuel vapor line (or it might be on the other framerail, I can't remember ) - maybe it's leaking little.

      I think it's a Brazilian filter-dwelling snake.
