• at least one vapor inlet port connectable to a fuel tank vent line,
• at least one atmospheric vent port,
• an outer housing member defining the first compartment as a first outer compartment,
• an inner housing member defining the second compartment as a second inner compartment, the first outer compartment encompassing the second inner compartment,
• wherein the inner housing member is fitted into the outer housing member at one end of the housing such that a wall of the inner housing member engages an inner wall of the outer housing member, and
• wherein the inner housing member and the outer housing member are sealed against each other by a closure cap covering at least a front face of the inner wall of the outer housing member and at least the front face of the wall of the inner housing member,
• wherein the inner housing member and the outer housing member are fitted into each other such that the front face of the inner wall of the outer housing member and the front face of the wall of the inner housing member are aligned and sealing is provided by the closure cap covering the aligned front faces of the inner wall of the outer housing member and the wall of the inner housing member.
