What is the main function of the fuel filter in a 12N Crawler Tractor?

The primary function of the fuel filter in a 12N Crawler Tractor is to prevent contaminants from damaging the engine. It plays a critical role in ensuring that only clean fuel reaches the engine components. Fuel may contain dirt, rust, water, and other impurities that can cause significant wear and tear or even catastrophic failure if allowed to enter the engine's fuel system. By filtering out these harmful particles, the fuel filter helps maintain optimal engine performance, prolongs the life of the engine, and reduces the likelihood of costly repairs. This function is essential for the reliability and efficiency of the tractor's operation, making it a crucial element of the fuel system.
