What is the fuel filter in the excavator?
A fuel filter is a filter in the fuel line that screens out dirt and rust particles from the fuel, normally made into cartridges containing a filter paper. They are found in most internal combustion engines. Fuel filters serve a vital function in today's modern, tight-tolerance engine fuel systems.
What are the symptoms of a bad fuel filter?
Symptoms of a Bad Fuel Filter
Lack of engine power. An overall lack or engine power in all gears can be due to a lack of fuel getting to the injectors.
Engine stalling under strain. If you find that the engine is losing power under hard acceleration or going up a steep incline, then it may be down to a bad fuel filter.
Random engine misfire.
