Which of the following may indicate a fuel system issue during an inspection?

Visible fuel leakage or strong fuel odors are significant indicators of a fuel system issue during an inspection. These symptoms suggest that there may be a problem such as a leak in the fuel lines, a faulty fuel injector, or issues with the fuel tank. Fuel leaks can pose serious safety hazards, including the risk of fire or explosion, and are critical to address immediately. Detecting strong odors often points to incomplete combustion or fuel not reaching the combustion chamber properly, which further emphasizes that the fuel system is not functioning as it should.

Addressing these concerns is crucial for ensuring the vehicle's safety and compliance with inspection standards. The presence of such issues not only affects vehicle performance but also raises serious safety risks that need to be mitigated during the inspection process.
