Water Detector senses water that has collected in the fuel filter within the fuel filtration assembly.

Diesel fuel carries water that the filter separates and holds in its base. When the accumulated water reaches the detector, it signals the engine management system to warn the driver that the filter needs draining, protecting the injection system from water ingress. For Lion turbo diesel applications.

Frequently asked questions

What does the water detector do?
The water detector senses water collected in the diesel fuel filter on Discovery 3, Discovery 4 and Range Rover Sport diesels. Diesel carries water that the filter separates and holds in its base; when it reaches the detector, the sensor warns the driver to drain the filter.
Where does the water detector fit?
The water detector fits into the base of the fuel filter assembly, where separated water collects. It threads into the filter housing on the listed Lion diesel engines, sitting at the lowest point so it detects accumulated water before it reaches the injection system.
Which models use this water detector?
This water detector fits the Discovery 3 (2005-2009), Discovery 4 (2010-2016) and Range Rover Sport (2005-2013) diesels. Engine and VIN breaks vary between models, so use your VIN to confirm the correct part for your fuel filter assembly.
