Is the sensor ‘Sedimenter’ located at the dashboard in some diesel trucks and vans really important?

    In colder climates, or high humidity climates water tends to build up more quickly in the fuel system.

    Water separators, and sediment bowls are a simple way of draining the icky stuff and water before it clogs up the filter, or gets into the injectors.

    Saves on replacing the filters too.

    Yes, the “Sedimentor” sensor light/buzzer in a diesel truck or van is important; and this is because once it gets ‘On’, it is telling the driver that it is about time that you start removing the water/sediments that has accumulated in a special area of the diesel fuel tank.

    The only reason why other trucks/vans don’t have this sensor in its dashboard is simply because the manufacturer(s) concern have incorporated the sedimentor mechanism in the vehicle’s fuel filter, such that every time the fuel filter is changed, the accumulated water/sediments are also removed. This is unlike the first type of diesel vehicles I discussed earlier where a sedimentor mechanism is provided and separated with the fuel filter. The rational behind this, other than efficiency, is to prolong the life and utility of the vehicle’s fuel filter.

    And by the way, water in diesel fuel is a natural occurrence especially during cold, damp and high humidity.
