AI Explanation
The correct answer is C) Rotating the gas generator. Explanation: The gas turbine fuel manifold pressure is established by rotating the gas generator. This action increases the fuel flow to the engine, which in turn increases the fuel manifold pressure. The other options are incorrect because: A) Closing the fuel recirculating valve would not increase the fuel manifold pressure. B) and D) Starting the fuel service pumps would not directly affect the fuel manifold pressure.
