Abstract
Systems are provided for a fuel system comprising an external refueling request switch accessible at or near a refueling door, thus enabling methods that may include initiating depressurization of a fuel tank responsive to an operator engaging the refueling request switch. The status of depressurization may be communicated to the operator via on one or more LED displays located either inside the refueling assembly or located at the refueling door. In this way, refueling requests may be initiated by a refueling operator, and by relaying the status of depressurization to the operator, any confusion on the part of the operator may be avoided.
