1. Malfunction of the Fuel water separator-white smoke from the engine.
The damage of the Fuel water separator will cause the engine to emit white smoke, because the water in the fuel will turn into water vapor when it is burned, and white smoke will appear.
The water vapor in the white smoke will damage the high-pressure fuel injectors, resulting in insufficient engine power, and sudden shutdowns. In severe cases, the engine will be directly damaged.

2. Fuel water separator failure-carbon deposit.
If the Fuel water separator is damaged, the water and impurities in the diesel will pass through the filter device, and then accumulate in the intake valve, intake duct, and cylinder, forming hard carbon deposits over time, which will affect the operation of the engine and cause the engine to be destroyed in severe cases.
Damage to the Fuel water separator will cause valve carbon deposits, and valve carbon deposits will cause engine start-up difficulties, unstable idle speed, poor acceleration, rapid refueling and tempering, excessive exhaust gas, and increased fuel consumption. In severe cases, it will cause engine damage.

3. Fuel water separator failure-the engine is unstable in acceleration or weak in acceleration, and it emits black smoke.
The high-pressure fuel injector in the high-pressure common rail system requires precise control of fuel injection pressure, fuel injection time, and fuel injection volume. The workmanship of the fuel injector is relatively fine. If there is a problem with the Fuel water separator, the water and impurities in the diesel fuel will wear and tear the plunger and even parts in the fuel injector until the injector is stuck.
Damaged fuel injectors can cause unstable or weak acceleration of the engine, or failures such as black smoke emission. In severe cases, it will directly damage the engine. Due to the fine workmanship of the fuel injector, its price is relatively high. Based on the above reasons, when there is a problem with the Fuel water separator, it must be replaced in time. Here, Tanaka Industry and Trade has carefully prepared an Fuel water separator disassembly and assembly wrench for you.
