What is a common symptom of a clogged fuel line in agricultural machinery?

A common symptom of a clogged fuel line in agricultural machinery is that the engine may hesitate, stall, or run poorly. When a fuel line is obstructed, the flow of fuel to the engine is restricted, which can lead to insufficient fuel supply. This deficiency can cause the engine to not receive the necessary amount of fuel to maintain consistent power and performance. As a result, the engine may struggle to operate, displaying symptoms such as hesitation during acceleration, unsteady idling, or stalling entirely, especially under loads or during high demand scenarios.

In contrast, the other scenarios do not align with the reality of a clogged fuel line. Running smoothly without issues would indicate that fuel is flowing freely into the engine, while quick acceleration without hesitation suggests optimal fuel delivery. Faulty readings on a fuel gauge are related to electrical or sensor issues rather than fuel flow problems. Thus, the manifestation of engine performance issues is a clear indicator of a clogged fuel line.
