• the fuel pump further comprising an electronic controller configured to select the appropriate fuel based on at least one signal received from the nozzle assembly;
• the nozzle assembly comprising:
• a valve subassembly including a trigger portion;
• a nozzle spout in fluid communication with the nozzle fuel channel, the nozzle spout including a dispensing tube defining an outlet and having a stop member affixed to an exterior thereof,
• a cylindrical collar slidably mounted on the nozzle spout, and a spring disposed on the exterior of the dispensing tube between the stop member and the collar;
• wherein the nozzle spout is configured to generate a collar position signal based on a position of the cylindrical collar on the dispensing tube when the dispensing tube is inserted into a fuel filler neck of the specific vehicle, and wherein the controller is configured to select the appropriate fuel based on the collar position signal received from the nozzle spout.
