About fuel filter
A fuel filter is a filter that is found in the fuel line. It performs the task of screening the dirt and rust particles from the fuel, generally turned into cartridges containing a filter paper. These fuel filters can be found in the internal combustion engines as they serve the primary function in the modern tight tolerance engine fuel systems. It is imperative to use it as unfiltered fuel contains numerous kinds of contamination such as paint chips and dirt. If not removed, these lead to rapid wear and failure of the fuel pump and injectors because of abrasive action of particles on the high precision parts present in the injection systems.
What is the purpose of fuel filter?
A fuel filter serves the primary function of filtering the fuel. It can be found in the fuel line. These filters are employed in both gas and diesel vehicles to extract the huge amount of dirt, rust and debris that tends to settle out of the fuel onto the bottom of the fuel tank, if not checked regularly. So in order to prevent clogging of sediments and maintain the operations of high precision parts present in the injection systems, it is essential to probe the fuel filter from time to time.
How fuel filter works?
A fuel filter has a filter medial and an inlet and outlet for the entry and exit of the fuel. When the fuel pump pushes fuel along the fuel lines at high pressure, this leads the fuel to move through the filter media. The filtration media is porous and according to the size of pores, the fuel flows through leaving the particles behind. Also, in a number of fuel filters, specifically the ones in diesel engines, a mechanism is present that removes the water from the fuel. A bowl is present at the bottom where the water separates from the fuel and the dust is collected. The drain valve enables the emptying of the water bowl. The filters are also fitted with a water sensor to send a dashboard warning at times when the water requires a cleansing.
Where is fuel filter located?
The fuel filters are mounted somewhere between the fuel pump and the engine while most of the modern vehicles have the filter in the fuel tank with some fuel pump assemblies integrating the fuel filter inside them. The older vehicles had the fuel filter present under the body, connected to the fuel line. Numerous vehicles have the filter present on the engine bay where the pollutants are removed. Therefore, the filter’s location depends on a number of factors such as car make, model and year of manufacturing.
