The fuel filter is behind the left rear wheel
The fuel filter on a ML320 W163 is located behind the left rear wheel. To access the fuel filter, you will need to remove the left rear wheel and wheel liner. It is attached to the top of the frame rail in a tight location.
When replacing the fuel filter, you may need to partially move the driver's side rear seat. The driver's side rear tire and liner must also be removed to access the filter. It can be quite difficult to remove the original filter. Some people have been able to do this with just their fingers, while others have used a special tool, such as pliers.
It is important to note that in April 2001, after the 2001 models were released, Mercedes-Benz changed the design of the filter, making it longer and requiring additional lines. Therefore, the year of your ML320 W163 will make a difference in the type of fuel filter you need and the replacement process.
Upgrading to a newer fuel filter may require three new fuel lines. Additionally, upgrading to a larger filter can help reduce dirt in the gas, leading to less engine wear and improved performance.

The fuel filter is one of the necessary components of the engine system
The fuel filter is located behind the left rear wheel of the ML320 W163. To access the filter, one must remove the left rear wheel and wheel liner. It is attached to the top of the frame rail in a tight location.
Fuel filters should be replaced at regular intervals as recommended by the auto manufacturer to ensure the longevity of the vehicle. The recommended interval varies depending on the vehicle's age and the manufacturer's maintenance schedule. For instance, some older models suggest replacing the fuel filter every 20,000 miles, while others suggest intervals of 70,000 miles. Newer models with advanced fuel systems may have integrated fuel filters designed to last the vehicle's lifetime.
It is essential to be aware of the signs that your vehicle may need a new fuel filter. One common sign is difficulty starting the vehicle, which may be due to clogged filters causing a reduction in the fuel flow rate. Excessive vibration while idling and rough cruising at slow speeds can also indicate clogged filters, as highway speeds require a higher fuel flow rate that may mask the problem. Therefore, it is crucial to adhere to the recommended replacement intervals and maintain a smooth-running engine.
