Abstract: A system comprising a drain for a fuel-water separator (FWS) assembly and a sensor is disclosed. The sensor may include a sensing element that is attached to the drain, wherein, when the drain engages the FWS assembly, a cavity is formed by an endcap at least partially within the FWS assembly and by at least one of the drain or the sensor, wherein the sensing element is exposed within the cavity, wherein a first side of the cavity is at least partially open, and wherein a second side of the cavity is formed by at least one of the drain or the sensor, wherein the cavity is configured to receive fluid through the first side and collect the fluid in the cavity to trigger the sensing element. Numerous other aspects and systems are disclosed.
