[Fuel Filter]
A fuel filter is a filter in the fuel line that screens out dirt and rust particles from the fuel. They are found in most internal combustion engines.
Some filters, especially found on diesel engines, are of a bowl-like design which collect water in the bottom (as water is more dense than diesel). The water can then be drained off by opening a valve in the bottom of the bowl and letting it run out, until the bowl contains only diesel. It is especially undesirable for water to be drawn into a diesel engine fuel system, as the system relies on the diesel for lubrication of the moving parts, and if water gets into a moving part which requires constant lubrication (for example an injector valve), it will quickly cause overheating and unnecessary wear. Also, because diesel engines require large amounts of compression to operate, water in the fuel system can be very dangerous as water cannot be compressed and may cause considerable engine damage. This type of filter may also include a sensor, which will alert the operator when the filter needs to be drained.
