Engine fuel-water separator – maintenance of fuel-water separator

I believe many friends are familiar with the waterproof of the fuel-water separator. Just unscrew the drain valve under the fuel-water separator and drain the water. The fuel-water separator with automatic drainage function is simpler. As long as the alarm signal is received, the water can be drained by pressing the waterproof button in the cab. After the water is drained, the water drain valve will be automatically closed, so that the water in the fuel-water separator can be drained in time. But water drainage is not as simple as we think. In fact, there are many things to pay attention to. Next, let’s talk about the points needing attention when draining water from the fuel-water separator.

(1) Discharge water in time

During routine maintenance every day, we should check the fuel-water separator. If there is too much water in it or it exceeds the warning line, we should drain it in time. Water drainage is frequent. First, after the fuel consumption is complete, the water in the fuel-water separator needs to be drained in time. Secondly, after replacing the fuel filter, the water in the fuel-water separator should also be drained in time. Do not forget to fill the fuel after draining the water. After draining the water from the fuel-water separator, remember to fill the fuel pump until the fuel pump is filled. Otherwise, it will affect the vehicle start!

(2) Pay attention to the insulation of fuel-water separator in cold weather

Put a thick cotton coat on the fuel-water separator. In the north, some users will heat the fuel-water separator in order to prevent it from being damaged by freezing, that is, wrap a layer of thermal insulation material; Select fuel-water separator with electric heating function. This can not only prevent the fuel/water separator from freezing, but also prevent the diesel fuel from waxing.
