What is the effect of a clogged fuel inlet screen on engine performance?

A clogged fuel inlet screen restricts the flow of fuel into the engine, leading to significant performance issues. The fuel inlet screen serves as a filter to prevent debris and contaminants from entering the fuel system, ensuring that clean fuel is delivered to the engine. When this screen becomes clogged, it obstructs the amount of fuel that can pass through, resulting in inadequate fuel supply.

As a consequence of the restricted fuel flow, the engine may experience symptoms such as poor acceleration, rough idling, and a decrease in overall power output. In severe cases, the engine may not start at all if the fuel supply is too limited. Proper maintenance of the fuel system, including regularly checking and cleaning or replacing the fuel inlet screen, is essential to ensure optimal engine performance and reliability.
