An evaporative emission control system for an automotive vehicle having an internal combustion engine and a fuel tank includes a membrane module disposed and connected between the internal combustion engine and the fuel tank, and configured to reduce discharge of fuel vapor generated from the fuel tank to the atmosphere. The membrane module includes a first passage and a second passage separated by a membrane, and the fuel vapor permeates the membrane in the membrane module. The evaporative emission control system further includes a buffer-volume housing connected to the membrane module by an additional passage and configured for storing fuel-rich vapor that has permeated the membrane. Furthermore, the evaporative emission control system includes an activated carbon filter disposed between the fuel tank and the membrane module, and a purge valve disposed between the membrane module and the engine.
