 Diesel Water Watch Kit for
Toyota 200 Series with 3 Batteries

Protect your diesel fuel system from contaminated diesel with our pre-filter Diesel Water Watch kit.

Diesel Water Watch is easily fitted before the factory filter, and will continually check the incoming fuel, sounding an audible and visual alarm if water is detected.

Diesel Water Watch does not use filters so does not cause restriction in the fuel system.  Diesel Water Watch removes and traps fuel contamination preventing damage to fuel pumps, injectors and common rail.

  • No filters to restrict fuel flow or vehicle performance.  Filters can’t stop or separate water under even light pressure or suction.

  • Water Watch has a patented electronic sensor, not a float or electrode system, so function is not reduced by the presence of particulates or sludge in the fuel collecting around the water detector.  

  • Patented Diffuser system is designed to effectively remove water and contaminants from fuel at high flow rates.  The Sensor is easily removed to drain off contaminants held in the glass bowl away from the main fuel flow.

  • It’s not a sedimenter, so you’re not relying on the water and particulates to settle into a bowl for the alarm to work (which, is often too late for your fuel system; contamination happens very quickly with the high flow rates in Common Rail Diesels).

  • All components of Water Watch are designed to operate at high temperatures, high pressures and high fuel rates used by Common Rail Diesels.  No distortion or malfunction of components.  Water Watch components have a lifetime guarantee.

  • No regular maintenance or replacement required.  Visual checks will let you know the quality of your fuel and you can see any contamination. 

  • Water Watch is available to fit any common rail diesel fuel system from small cars through to larger vehicles, including industrial and marine applications.

  • Bracket kits are available to fit most popular common rail diesels – making Water Watch very easy to install.
