Which component is designated as the overspeed and drain valve in the UH-60S fuel system?

• A. Main Fuel Manifold
• B. Engine Driven Boost Pump
• C. Overspeed and Drain Valve
• D. Fuel Pressure Sensor

Answer: (C)

In the UH-60S fuel system, the overspeed and drain valve is the component whose job is to protect engine operation by venting or draining fuel when a rapid RPM/pressure increase occurs. Its function is to relieve excess fuel pressure and provide a drain path when needed, which is why the designation itself identifies the valve responsible for these tasks. The main fuel manifold distributes fuel to the engines, the engine-driven boost pump increases fuel pressure, and the fuel pressure sensor monitors pressure—none of these perform the overspeed relief and drainage role.
