FL-2RA-12: The FL-2RA-12 was designed to be used on a 12-volt system with resistive fuel level sensors. The fuel level sensor's resistance may increase or decrease as fuel is added to the tank and the maximum resistance must be between 90 and 270 ohms. FL-2RA-24: The FL-2RA-12 was designed to be used on a 24-volt system with resistive fuel level sensors. The fuel level sensor's resistance may increase or decrease as fuel is added to the tank and the maximum resistance must be between 90 and 270 ohms.
