What a fuel filter does?

Compare this to drinking water filters – you are trapping or removing the undesirable and mostly invisible components from the water you are about to consume. A fuel filter is a device that traps (filters) particulate matter from fuel as the fuel is delivered to the engine. All fuels are likely to contain certain amounts of particulates (dirt) which is undesirable and is, in fact, harmful to your engine’s fuel system (pumps and fuel injectors). Proper filtration of fuel will prevent you from damaging fuel injectors and fuel pumps but in this process, the fuel filter becomes loaded (clogged) so routine replacement of fuel filters is recommended.

Everything You Need To Know About Your Car’s Fuel Filter

fuel filter, like most parts of your car, is absolutely necessary for proper engine performance. However, unlike most essential parts like your car’s wheels, or engine block, you’ve probably never heard of your fuel filter – and its maintenance is probably not on the top of your priorities. What is a fuel filter? Where is it located? And what are the signs of its failure?

What is your fuel filter?

Your car uses gas from your fuel tank to power your engine. However, small impurities such as dirt, debris, or other particulate matter can adversely affect the performance of your engine. The fuel filter was designed to catch these small impurities in your gas before it enters your engine, so only pure gasoline is used. Your fuel filter functions much like an air filter; catching particulate matter in a fine film before it can pass into your engine. Some newer cars come with a simple fuel strainer, that is replaced only with the full fuel assembly.

Where is the fuel filter located?

The fuel filter is located somewhere in between your fuel tank and your engine. Typically, the fuel filter is either located inside the fuel tank (in the opening of the fuel line, which feeds gas to your car), or somewhere in the fuel line (this is usually at the bottom of your car.) If you are unsure of your fuel filter’s location, your car’s documentation will contain a precise answer.

When should I change my fuel filter?

Like any filter, your fuel filter catches the dirt and other debris. As your car’s life goes on, the fuel filter can become clogged and dirty, which may impact your car’s performance, allowing fuel with particulate matter to pass into your fuel injector, or, stopping the optimal flow of fuel. Earlier in the industry, the lifespan of a fuel filter was quoted as 30,000 to 60,000 km, however, with fuels getting more and more pure, a fuel filter can operate optimally for up to 100,000 km. Paradoxically, changing your fuel filter for the first time above mileages of 150,000 km can cause engine failure; this is most likely because your fuel pump works harder to overcome the dirty filter. You should exercise caution when changing your filters at these mileages, and consult a mechanic before completing them.
