It's usually inside the fuel tank or along the fuel line
The fuel filter is an integral part of the fuel supply system in your vehicle. Its purpose is to clean the fuel in your car before it reaches the engine. An unclogged filter prevents contaminants like dust, dirt, and rust from entering the combustion and fuel chambers by removing these particles. This helps keep the engine performing optimally.
There are two common locations where fuel filters are mounted in vehicles. The most common location for modern vehicles is along the fuel line on the bottom of the car, just past the fuel pump. In some vehicles, the fuel filter is located in the engine bay on the line that leads to the fuel rail. Some vehicles may place the fuel filter in a different location, so refer to your service manual to find out for sure.
The exact location of the fuel filter depends on the vehicle’s make and model. For example, 1995-2002 Honda Accord models have the fuel filter near the brake master cylinder on the back of the engine. Some fuel tanks have internal, non-serviceable fuel filters. If the filter is installed inside the tank, you will need to drain the tank before you can remove the filter for inspection or replacement.
If your filter is installed in the fuel line, remove the metal clips on each side of the filter, using a screwdriver or needle-nose pliers, and slide the filter out of the fuel line. Place a bowl or bucket beneath the fuel filter to catch any fuel that drips or pours out.
