Which of the following is NOT a step in the fuel system inspection process?

In the context of the fuel system inspection process, focusing on the functions directly related to fuel management helps to clarify why checking the battery voltage is not a step involved in this specific inspection. The inspection process primarily concentrates on components that directly affect the delivery and quality of fuel to the engine.

Pressure testing the fuel tank is crucial as it ensures that there are no leaks and that the system can maintain the necessary pressure for optimal fuel delivery. Obtaining a sample from the carburetor allows for the assessment of fuel quality, which is essential for identifying any contaminants that could affect engine performance. Inspecting the fuel filter condition is vital to confirm that it is not clogged and is effectively filtering impurities from the fuel before it reaches the engine.

In contrast, checking the battery voltage, while important for overall vehicle operation, pertains more to the electrical system rather than directly evaluating the fuel system. Thus, it does not fit within the fuel system inspection process, which focuses on components and procedures integral to fuel supply and management.
