Crossover protection system graphical user interfaces, crossover protection systems that display graphical user interfaces, and methods for pairing tank delivery connectors with product delivery vehicle systems are provided. A tank delivery connector reads a tank tag with a tank tag reader, and transmits a tank tag indicator associated with the tank tag with network interface hardware. An electronic control unit receives the tank tag indicator with network interface hardware, determines a distribution tank fuel type associated with a distribution tank based on the tank tag indicator, determines that the tank delivery connector is associated with a tank compartment of a product delivery vehicle based on the tank tag indicator, and displays a graphical user interface on the display. The graphical user interface includes a tank delivery connector graphic displayed proximate a tank compartment graphic to indicate that the tank delivery connector is associated with the first tank compartment.
