Abstract: Methods and systems are provided for reducing an amount of fuel vapors that are routed to a fuel vapor storage canister during a refueling event, in response to an indication that a fuel dispenser that is dispensing fuel to a fuel tank is underperforming. In one example, a method comprises increasing a pressure in the fuel tank responsive to an indication that the fuel dispenser is dispensing fuel at a first rate that is at least a threshold amount below a second rate, without changing the first rate at which the fuel dispenser is dispensing the fuel. In this way, fuel vapor recirculation may be improved and an amount of fuel vapors routed to the canister reduced, which may thus reduce opportunities for release of undesired evaporative emissions to atmosphere.
