Are restarts possible with both an engine-driven low-pressure fuel pump and boost pump failure?

In the scenario where both the engine-driven low-pressure fuel pump and the boost pump have failed, restarts of the aircraft engine are not possible. The engine-driven low-pressure fuel pump is essential for delivering fuel from the tank to the engine at the required pressure, while the boost pump is critical for maintaining fuel flow, especially during engine start and low fuel situations. If both pumps are inoperative, there is no way to ensure that fuel reaches the engine, which is necessary for ignition and proper operation.

This mechanical disadvantage highlights the importance of these systems for engine functionality. Without fuel pressure, the engine cannot start or be restarted, leading to the conclusion that restarts are not feasible in this situation. Understanding this relationship between fuel system components is vital for assessing emergency procedures and capabilities of the T-6A aircraft.
