Overview

Fleece Performance Donaldson WIF Sensors

Fleece Performance Donaldson Water-In-Fuel (WIF) sensors are combination twist-and-drain valve and electronic water detection sensors designed for aftermarket diesel fuel filtration systems. They're built specifically to work alongside Fleece underbed and underhood fuel filter conversion kits—such as popular setups for Ram 2500/3500 trucks with the 6.7L Cummins diesel engine.

* What the sensor does:
-- Water detection: It continuously monitors your diesel fuel water separator for water contamination, triggering a dashboard warning light before fluid can reach and ruin expensive high-pressure fuel injectors or common-rail components
-- Drain valve function: It doubles as a physical petcock or twist valve, letting you easily drain accumulated water and
debris out of the filter canister during routine maintenance
* Key features:
-- Design: Combines a twist-operated drain valve with an integrated electronic WIF sensor in a single screw-in component
-- Plug-and-play: Uses factory-style connections or specific adapter harnesses so you can retain stock sensor functionality without cutting or modifying original vehicle wiring
