A capless fuel unit having an elongated housing open at each end and defining a first and a second longitudinally spaced fluid ports. First and second door assemblies each include a flapper valve associated with a first fluid port and a second flapper valve with a second fluid port, the flapper valves being movable between open and closed positions and resiliently urged toward their respective closed positions. A pressure relief valve is at least partially contained within an interior of the flapper valves. The various plastic components of the capless unit incorporate Graphene or a Graphene-derivative for resisting hydrocarbon emission from fuel vapors escaping from the unit to the atmosphere.
