An excessively restricted fuel filter may cause which of the following?

An excessively restricted fuel filter can lead to inadequate fuel flow to the engine, resulting in a stalling condition. When the fuel filter becomes too clogged, it restricts the amount of fuel that can reach the engine, which is necessary for maintaining proper combustion and engine function. If the engine does not receive enough fuel, it can starve, leading to interruptions in power and ultimately causing it to stall. This scenario is particularly critical in small power applications where consistent fuel delivery is essential for reliable operation.
