About fuel filter
A fuel filter is a filter contained inside the line of petrol. It performs the task of screening the particles of dirt and rust from the fuel, generally converted into cartridges containing a filter paper. Such fuel filters can be used in internal combustion engines as they serve the primary role in the fuel systems of the modern tight tolerance engine. As unfiltered fuel contains various forms of waste, such as paint chips and debris, it is important to use it. Unless removed, these results in rapid wear and failure of the fuel pump and injectors due to abrasive action of particles on the high-precision parts present in the injection systems.
What is the purpose of fuel filter?
A fuel filter performs the primary filtering purpose for the air. You can find this in the fuel line. These filters are used in both gas and diesel vehicles to extract, if not checked regularly, the huge amount of dirt, rust and debris that tends to settle out of the fuel onto the bottom of the fuel tank. It is therefore essential to test the fuel filter from time to time in order to prevent sediment clogging and to maintain the operations of high-precision parts present in the injection systems.
How fuel filter works?
A fuel filter has a medial filter and an inlet and outlet for the fuel to enter and exit. When, at high pressure, the fuel pump moves fuel along the fuel lines, this allows the fuel to pass through the filter media. The filtration media is porous, and the fuel flows by leaving the particles behind according to the size of the pores. A mechanism that extracts the water from the fuel is also present in a variety of fuel filters, especially those in diesel engines. There is a bowl at the bottom, where the water separates from the fuel and collects the particles. Drain valve allows water bowl to be emptied. The filters are also equipped with a water sensor to give a dashboard warning at times when cleaning is needed for the water.
Where is fuel filter located?
The fuel filters are mounted somewhere between the fuel pump and the engine while most modern vehicles have the filter inside the fuel tank with some fuel pump assemblies which integrate the fuel filter inside. The older cars, attached to the fuel line, had the fuel filter present under the chassis. Many vehicles have the filter in the engine bay, where the pollutants are removed. Hence the position of the filter depends on a variety of factors such as the manufacture of the vehicle, model and year.
