What You'll Learn

The fuel filter is located just inside the driver's side wheel well
The fuel filter on a 2002 Mercedes C240 is located just inside the driver's side wheel well. It is not inside the wheel well itself, but just beyond it. The fuel filter is fairly large in diameter, and you will notice three hoses leading into it.
When changing the fuel filter, you will need to replace the clamps as they are the type that must be broken to change the filter. You can buy special hose clamps at most auto parts stores, but you can also use vice grips, as long as they are not too tight.
Before starting the car, turn the key to the second position and wait for the fuel pump to kick in. This will take a minute or so to allow the system to pressurize.
The fuel system is pressurized, so removing the gas cap will prevent fuel from running out.

It's next to the rear wheel and rear spring
The fuel filter on a 2002 Mercedes C240 is located on the driver's side, next to the rear wheel and rear spring. It is just inside the wheel well, not in it, but beyond it. It is fairly large in diameter, and you will notice three hoses going into it.
To access the fuel filter, you will need to remove the gas cap. The fuel system is pressurised, so removing the cap will prevent fuel from spilling everywhere. You will also need to remove the skid cover, which can be done with a lift or a jack. Once you have located the fuel filter, you will need to replace the clamps as they are the type that needs to be broken to change the filter.
The fuel filter is a round, silver canister, and it is mounted on the side of the fuel tank at the rear of the car. It should take around one hour to replace.
If you are unsure whether you have found the fuel filter, look for the rear spring—the fuel filter is located next to it.

It takes 1-1.2 hours to replace
The fuel filter on a 2002 Mercedes C240 is located just in front of the driver's side rear axle. The fuel system is pressurised, so it is recommended to remove the gas cap before attempting to replace the fuel filter to prevent fuel from running everywhere.
The replacement process involves unclamping the two upper hoses attached to the plastic filter holder and lifting it out. Wire cutter pliers can be used to cut the left-side hose clamps, and a flat-tip screwdriver can help pry the hoses from the base of the filter. Once the hoses are removed, the new filter can be installed using a small amount of oil on the O-rings to ease the re-installation of the quick-connect fittings.
After the new filter is installed, the hoses should be reattached in reverse order, tightened with a 1/4" socket, and the plastic filter holder should be reinstalled. The spilled fuel should be wiped up, and the four plastic 10mm nuts for the skid cover should be reinstalled. Finally, the lift/jacks should be removed, and the gas cap should be reinstalled.
The entire process should take approximately 1-1.2 hours and may require additional time for the system to re-pressurise, as there will be air in the fuel line. This can cause the car to take a few seconds longer to start, but the air will be forced out of the system once the car is started.
