Component Details: Water is separated by the filter medium using the repellent effect. Separated water gets collected in the bottom chamber of the sediment body. Sediment is mounted on the long member of chassis behind mud flap of left front wheel. The water-in-fuel (WIF) sensor senses the presence of water collected in the bottom chamber and provides the information to EMS ECU which lights WIF tell-tale on IC to indicate the driver. Collected water is drained manually by opening a water drain plug at the bottom of the sediment body. This helps to prevent corrosion & damage to components of common rail system.
