3-44. When the eductor causes a decrease in fuel pressure on top of the diaphragm of the shutoff valve, how will the shutoff valve be affected? 1. The filter discharge pressure will open the valve 2. The filter discharge pressure will close the valve 3. The tension spring will close the valve 4. The increase in filter discharge pressure applied to the top of the diaphragm will open the valve 3-45. What causes the automatic shutoff valve to close when the pilot valve closes? 1. Fuel pressure acting on the bottom of the diaphragm in the automatic shutoff valve 2. Fuel pressure being directed through the eductor suction line to the top of the cover chamber of the automatic shutoff valve 3. Fuel pressure being directed to the top of the diaphragm in the automatic water drain valve 4. Fuel pressure being directed to the bottom of the diaphragm in the automatic water drain valve 3-46. What are the operating positions of the rotary control valve? 1. Down and up only 2. Down and horizontal only 3. Horizontal and up only 4. Down, horizontal, and up 3-47. What valve directs filter pressure through its ports to the tops of the diaphragms of the pilot and automatic water drain valves? 3-48. When there is little to no water passing through the fuel filter and the ball float is in the DOWN position, the rotary control valve directs filter pressure to. and vents it to, which valves? 1. Directs to the top of the water drain valve and vents the top of the pilot valve 2. Directs to the bottom of the water drain valve and vents the top of the pilot valve 3. Directs to the top of the water drain valve and vents the bottom of the water drain valve 4. Directs to the top of the automatic shutoff valve and vents the top of the water drain valve 3-49. When all valves of the filter hydraulic system are open and coalesced water is draining from the sump, in what position will the ball float be? 1. Down 2. Vertical 3. Horizontal 4. Up 3-50. Under which of the following conditions will the pilot and automatic shutoff valves be closed? 1. The float is in the DOWN position with no water drainage required 2. The float is in the HORIZONTAL position and the accumulated water is draining 3. The float is in the UP position and the accumulated water is not draining fast enough 4. During normal operations 1. The pilot valve 2. The automatic shutoff valve 3. The rotary control valve 4. The automatic water drain valve 20
