Fuel filters are more important in today's vehicles because modern
designs include fuel systems with tight tolerances. Unfiltered fuel
may contain a lot of contaminants, such as paint chips, dirt, and
rust. These contaminants must be removed to prevent accelerated
wear and eventual failure of fuel pumps and injectors. The
particles on the high-precision parts of the fuel injection system
are abrasive, which can cause great damage and ultimately
unnecessary costs.
In order to obtain the best performance, the fuel filter in the car
should be replaced regularly according to the car manufacturer's
recommendation. Following the recommended maintenance schedule
provided by the car manufacturer will help ensure that your vehicle
reaches the lifespan you want.
