Methods and systems are provided for pinpointing a restriction in a vehicle evaporative emissions system which may adversely impact refueling and/or fuel vapor canister purging operations. In one example a method comprises conducting a diagnostic to identify a location of a restriction based on a rise time at which a pressure in a fuel system of a vehicle rises to a threshold pressure during a refueling event where fuel is added to the fuel system. In this way, a location of the restriction may be identified so as to enable appropriate mitigating action to be taken.
