1. A sensor assembly, comprising:
a sensor body having a first electrical connection, a second electrical connection, and a probe portion configured to be submerged in a fluid comprising a fuel;
wherein the sensor body comprises only two electrical connections consisting of the first electrical connection and the second electrical connection;
a signal input line supplying a signal voltage and power to the sensor from a voltage source to the first electrical connection of the sensor body;
a ground line connected to the second electrical connection of the sensor body; and
a controller configured to receive a signal output from the signal input line for determining a presence of water in the fluid.
