About Water Separators

A water separator removes free water from diesel before it reaches the main fuel filter and injection system. On common-rail engines, water is one of the most damaging contaminants: it corrodes precision parts, reduces fuel lubricity and promotes microbial growth in tanks. Where fuel is stored in drums, transported long distances or dispensed from small stations, a separator is a practical safeguard.

Frequently asked questions

Does a water separator replace the diesel fuel filter?

No. A separator is usually a pre-filter that removes water and coarse particles. The main fuel filter is still needed for fine filtration specified by the engine manufacturer.

How often should a water separator be drained?

Operators should drain it whenever the warning light shows or water is visible, and routinely at each service. In poor-fuel regions, daily or weekly checks are common practice for fleets.
