located at the inlet to the boost pump as was shown in Figure 14-50. The screen’s large area allows debris capture while still permitting sufficient fuel flow for operation. Regularly scheduled inspection and cleaning ... these strainers are required. An additional main strainer for the aircraft fuel system is required between the fuel tank outlet and the fuel metering device (in a carburetor or fuel-injection system). It is normally located between the fuel tank…

Figure 2-60. The impeller, which is driven at a greater speed than the high pressure elements, increases the fuel pressure depending upon engine speed. The fuel is discharged from the boost element (impeller) to the two high-pressure gear ... discharge port of the pump. This valve opens at a predetermined pressure and is capable of bypassing the total fuel flow. This allows fuel in excess of that required for engine operation at the time to be recirculated. The bypass…

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 (FOC). The 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…
