A fuel level sensor system is provided that passively protects fuel sensors and fuel tanks from receiving voltages from fuel level sensing electronics that exceed safety threshold values. The fuel level sensor system includes a safety barrier device that is located outside of a fuel tank. The safety barrier device includes a housing and a transformer located within the housing. The transformer is electrically coupled between fuel level sensing electronics and a fuel level sensor within the fuel tank. The transformer protects the fuel tank from voltages that exceed a predefined threshold value.
