The Davco Technology Water-In-Fuel Sensor is a replacement sensor used in the bottom port of Davco Fuel Pro fuel processors to restore water detection capability. It replaces the original probe when the dash warning light no longer activates or the sensor body becomes damaged. The Davco Technology 103806PAC sensor threads directly into the collection bowl area, allowing it to detect water accumulation where it naturally settles during operation. When functioning correctly, it signals the dash light so the separator can be drained before water moves beyond the processor. The housing is built to tolerate vibration and temperature changes commonly seen in engine compartments. Installing a new sensor restores the fuel processor’s ability to alert the driver to water buildup without replacing the processor assembly.
