Which sequence illustrates the correct fuel travel path in a Cessna 172?

The sequence that illustrates the correct fuel travel path in a Cessna 172 is from the fuel tank to the fuel selector and then to the engine-driven fuel pump. This path is essential for understanding how the fuel system operates in the aircraft.

Initially, fuel is stored in one of the fuel tanks, which is where the fuel is drawn from. Next, the fuel selector allows the pilot to choose which fuel tank's fuel will be used, ensuring the appropriate supply is directed to the engine. After the fuel is selected, it flows to the engine-driven fuel pump. This pump is crucial because it ensures that the fuel is delivered at the correct pressure and flow rate to the engine for combustion.

The other sequences provided do not accurately reflect the order in which fuel travels through the system in a Cessna 172. Understanding the correct path is crucial for proper aircraft operation and troubleshooting any issues that may arise with the fuel system.
