A positionable water in fuel indicator unit including an indicator housing having a back panel, and a housing cover connected to the back panel. The water in fuel indicator unit can also include a signal receiving device configured to receive a water in fuel signal from a water in fuel sensor located in the fuel filter, a first indicator visible through the housing cover and configured to indicate when a water level in the fuel filter is less than a predetermined threshold, a second indicator visible through the housing cover and configured to indicate when the water level in the fuel filter is equal to or greater than the predetermined threshold, and a controller enclosed by the housing cover. The controller can be configured to activate the first indicator based on the water in fuel signal, and activate the second indicator based on the water in fuel signal.
