If your truck is equipped with a factory Water-In-Fuel (WIF) Sensor, AirDog® HD Diesel Fuel Systems now offers a provision to enable you to utilize your factory WIF Sensor with the AirDog® System! Designed to mate to the AirDog® WS200-WD Water Separator with Drain, the Drain Valve with WIF Sensor includes a Water-In-Fuel Sensor and the most widely used female Deutsch connector to connect to the 2-wire harness lead from your truck. Simply install the Drain Valve with WIF Sensor into your WS200-WD, or into the optional Clear Bowl, connect the harness lead to the Deutsch connector, and enjoy the benefit of monitoring the water content in your AirDog® Water Separator from the OEM gauge in your dash! The integrated drain allows quick and easy draining of accumulated water directly from the WS200-WD Water Separator.
