Methods and systems are provided for an evaporative emission control system. In one example, a method may include halting a dispensing of fuel to a fuel tank during a refueling event by increasing a backpressure in the fuel tank. The halt to fuel dispensing may be executed based on one or more of an upcoming fuel vapor canister purge event and an estimated fuel vapor canister loading capacity to determine a predicted canister breakthrough. The predicted canister breakthrough may be compared to a threshold to regulate a refueling volume.
