What should be checked in the fuel system during an inspection?

The fuel system is critical for the proper functioning of a small engine, and conducting a thorough inspection is essential to ensure optimal performance and prevent potential failures. The correct choice highlights the importance of checking three specific aspects: the fuel tank for contamination, the installation of the fuel filters, and the integrity of the fuel lines by looking for holes or cracks.

Contamination in the fuel tank can lead to engine performance issues and can damage internal components. It's important to ensure that water, dirt, and debris are not present, as these can obstruct fuel flow and negatively affect combustion.

Checking the installation of the fuel filters is also crucial since improperly installed filters can lead to fuel starvation or leaks, which may cause the engine to run poorly or stall.

The fuel lines are another vital area of concern; any holes or cracks can result in fuel leaks, which creates a fire hazard and impacts engine efficiency. Maintaining the integrity of the fuel lines ensures that the fuel system maintains proper pressure and delivers the correct amount of fuel to the engine.

In summary, a comprehensive check of the fuel system as described ensures reliability and safety in the operation of small engines.
