The water filter has a glass bowl or bowl in its bottom. Since particles and molecules of water are thicker and heavier than fuel molecules, they do not pass through the small pores and enter the bottom of the filter when it enters the filter. The water enters this part because of the heavier fuel in the bottom of the pod. During daily service and during engine operation, the water inside the glass bowl is clearly visible in brown bullets and can be removed by opening the evacuation screw.
