Water Injection System Fuel Control Maintenance Fuel System Operation The fuel pump receives fuel from the airplane fuel system. The low pressure boost stage of the pump pressurizes the fuel and sends it to the fuel/oil cooler ... fuel flows from the FOC, through the fuel pump filter element, and then to the high pressure main stage of the pump. The high pressure main stage increases the fuel pressure and sends it to the fuel metering unit…

Figure 14-20. A fuel vent system with associated float and check valves that stop fuel and keep the tanks vented regardless of the aircraft attitude. Occasionally, defueling the aircraft is required for an inspection or repair. The same fueling ... station is used, and the hose from the fuel truck is connected to same receptacle used to fuel the aircraft. To allow fuel to exit the aircraft, a defueling valve is opened. Fuel can either be pumped…

Gate valves utilize a sealed gate or blade that slides into the path of the fuel, blocking its flow when closed. Figure 14-43 shows a typical hand-operated gate valve. When the handle is rotated, the actuating ... inside the valve moves the gate blade down between seals and into the fuel flow path. A thermal relief bypass valve is incorporated to relieve excess pressure buildup against the closed gate due to temperature increases. Motor-Operated Valves…
