An active purge pump system module is provided for an evaporative emission control (EVAP) system for a vehicle. The EVAP system includes a fuel tank, a vapor collection canister in communication with the fuel tank, an air intake, and a purge valve connected between the canister and the air intake. The active purge pump system module includes a pump in fluid communication with the canister to move air independently of operation of the engine. A bypass valve assembly communicates with an upstream side and a downstream side of the pump to bypass the pump. In a closed position of the bypass valve assembly, the pump, when activated, moves purge vapor from the canister, through the purge valve, and to the engine to be consumed during combustion, and when the bypass valve assembly is opened and the pump is deactivated, vehicle refueling is permitted.
