To access the fuel filter, you will need to remove the rear seat cushion and then take out the fuel pump. It is important to note that the fuel filter should be replaced every 60,000 miles or 5 years, whichever comes first.
When replacing the fuel filter, you do not need to change the pump at the same time. However, the pump must be removed to access the filter. The electrical connector for the pump is located on the left side, under the access panel for the fuel filter.
Before replacing the fuel filter, it is important to check the basics, such as spark, fuel injector pulse, fuel pressure, volume, quality, and engine compression. Additionally, listen for the fuel pump to run and check the fuses, relay, and fuel pressure.
A clogged fuel filter can lead to contaminants in the engine fluid, which can cause engine system failures. Replacing the fuel filter can help protect the fuel pump and fuel injectors from costly malfunctions.

The fuel filter should be replaced every 60,000 miles or 5 years
The fuel filter on a Mercedes E320 is located in the fuel tank and is part of the pump assembly. To access it, you need to remove the rear seat cushion and then take out the fuel pump. It is recommended that you replace the fuel filter every 60,000 miles or 5 years, whichever milestone comes first. This is because a dirty or clogged fuel filter can shorten the lifespan of the fuel pump and cause problems with the fuel trim, or the air/fuel mixture ratio.
While some sources suggest that the fuel filter should be replaced every 60,000 miles, others recommend doing so after 48,000 miles. However, some car owners have mentioned that they have driven over 99,000 miles with only one filter replacement at around 50,000 miles. Ultimately, it is up to the car owner's discretion to decide when to replace the fuel filter, as there may not always be a clear recommendation from the manufacturer.
It is worth noting that the fuel filter plays a crucial role in keeping the fuel pump and fuel injectors free from contaminants, which can lead to costly malfunctions if left unchecked. A fresh filter can extend the life of the fuel pump, and it is significantly more affordable to replace than a fuel pump. Therefore, it is generally advisable to err on the side of caution and replace the fuel filter every 60,000 miles or 5 years to maintain optimal vehicle performance and avoid potential issues down the line.
