Point-of-sale fuel dispensing systems, pump assemblies, and methods of dispensing fuel at point-of-sale. The system includes a market fuel storage tank, a pump assembly, a fuel conduit, a separation unit, a plurality of enriched fuel product tanks, and a controller. The separation unit may selectively receive at least a portion of the market fuel and convert it into an octane-rich fuel component and a cetane-rich fuel component, which may then be distributed to refueling vehicles, containing octane-rich or hexadecane-rich fuel components Fuel grade selection and retail payment for the fuel of the cetane fuel component are provided to the vehicle based on user input on the customer interface. |
