During continuous operation, what is the range for Fuel Pressure?

• A. 0-7 psi
• B. 7-15 psi
• C. 7-25 psi
• D. 15-25 psi

Answer: (C)

The correct range for fuel pressure during continuous operation in the TH-73A is 7-25 psi. This range is crucial for ensuring proper fuel delivery to the engines, allowing for optimal performance and efficiency. Within this range, the fuel system can adequately maintain pressure, ensuring that fuel is effectively delivered from the tanks to the engine, promoting sufficient combustion and preventing issues such as vapor lock or fuel starvation.

Maintaining fuel pressure within this specified range is essential for engine reliability and performance. If fuel pressure drops below 7 psi, it may result in inadequate fuel flow, while pressure above 25 psi could indicate a malfunction within the fuel system, potentially leading to component damage or failure.
