Which device works with the Transfer Valve to move fuel from the Center tank to the inner tanks?

• A. Transfer Valve
• B. Pump
• C. Jet Pump
• D. Transfer Valve and Jet Pump

Answer: (D)

The transfer from the center tank to the inner (wing) tanks relies on both a control path and a pumping action. The transfer valve opens the route between the center tank and the wing tanks, but it doesn’t move the fuel by itself. The jet pump provides the actual motive flow that pushes or siphons the fuel through that open path. So, you need the jet pump to supply the pumping action and the transfer valve to establish and control the flow path. Without the valve open, nothing would transfer; without the jet pump, there’s no pushing force. That combination is why the correct answer is the transfer valve and jet pump.
