The fuel filter is built into the fuel pump, which is inside the gas tank

From 2009 onwards, the Ford Focus fuel filter was changed to a "life-time" filter that is built into the fuel pump, which is located inside the gas tank. This means that, unlike with the 2002 model, the fuel filter on these later models cannot be accessed or replaced.
To replace the fuel filter on a 2002 Ford Focus, you will need to get under the car and locate the filter in the gap between the fuel tank and the floorpan for the footwell. You will need a 10mm socket to pull down the bracket it is attached to. Then, unhook the short plastic line and push the fitting in towards the filter to release it.
There is a short section of line that goes from the hardline to one end of the filter, and it is easiest to remove this piece first. Then, you can unbolt the filter and undo the fitting from the other end. Be aware that some fuel may drain out of the line when you do this. To install the new filter, simply follow these steps in reverse.

To replace the fuel filter, you may need to remove the output side of the filter
To replace the fuel filter on a Ford Focus, it is important to first ensure adequate ventilation of the workplace as fuel vapors are poisonous. All work should be done with the engine switched off.
One method to replace the fuel filter is to remove the output side of the filter, which will cause fuel to drain out. This can be done by removing the fuel pump fuse and turning the car over a few times to depressurize the fuel lines. Then, remove the line on the output side by squeezing the red clip together. Once the output side is removed, the filter can be dropped down with the bracket and turned to expose the removable side of the fuel line clip.
Another method is to Unhook the bracket first, which makes it easier to remove the first line and fool around with less gas spilling out.
When removing the fuel filter, do not use excessive force as this may damage the part. Additionally, do not remove the white clip from the fuel line as this can break it. Instead, press on the flat white side, pushing the clip into the connector, and then pull to remove.
To install a new fuel filter, make sure that the fuel flow direction mark is considered and that dust and dirt do not get into the fuel filter housing. Connect the fuel lines to the new fuel filter and tighten the fasteners using a drive socket and torque wrench to 8 Nm torque. Clean the connector of the fuel pressure sensor with dielectric grease and attach the fuel pressure sensor connector. Finally, install the fuel filter fastening bracket and screw in the fixing bolts.
