The Mercedes-Benz ML320 is a car model that has been in production since at least 1994. As with any car, the ML320 requires regular maintenance and servicing to ensure optimal performance and longevity. One aspect of ML320 maintenance that has been discussed in online forums is the replacement of fuel hoses and lines. The ML320 appears to have a fuel filter loop line that connects to the engine and can be challenging to disconnect and remove. ML320 owners have also encountered issues with fuel breather lines being too small for new filter nozzles. ML320 owners can purchase fuel hoses and lines from various retailers, with some offering original equipment manufacturer (OEM) parts.

ML320 fuel filter loop line disconnection instructions
The fuel filter loop line in the ML320 was designed to accommodate the extra length of the new-sized filter. Removing it can be challenging, and visual guides may be helpful.
To disconnect the fuel filter loop line from the line going towards the front of the car, you need to identify the correct connector. It is not the connector with two tabs on the side that you push and pull up with the special Mercedes pliers. Instead, it is the loop line that goes from the back of the filter, under it, and connects to the line that goes to the engine. It has a small strap on the side of the connector that you can push or pull to release the line's ring from the inside. Be very careful not to damage the connector.
To disconnect the line, use a pick tool to manipulate the connector. Keep prying and pushing the little C-clip inside the connector while simultaneously pulling the line. Apply some WD-40 to help slide the hose out.
The loop line was only necessary for vehicles between 1998 and 2000. After that, all new lines were installed at the assembly plant.

ML320 fuel filter replacement and breather line issues
The fuel filter in a Mercedes ML320 is located in the fuel tank. To replace it, you will need to remove the rear seats to access and replace the fuel lines. You will also need to remove the plastic panels under the seat, fold and slide it forward, and pull up the carpet to expose the access port for the fuel pump.
There are various fuel filters available for the ML320, depending on the model year of your vehicle. For example, the Dade Fuel Filter 1634770201 1634770701 is compatible with the 1999 and 2001 ML320 models. The Bomunik Fuel Filter, on the other hand, is compatible with the 2002-2005 ML320 models.
When replacing the fuel filter, it is recommended to also replace the fuel lines. The fuel lines can be removed by pushing them on, then squeezing and finally pulling them away. However, some people have reported difficulties in removing the lines without the special tool.
One common issue with the ML320 fuel filter replacement is the breather or vent line being too small for the larger nozzle on the new filter. This can make it challenging to connect the line to the filter. Additionally, some customers have reported that the fitting on the fuel filter breaks easily when removing it, even with minimal force applied.
Another issue that has been reported is difficulty in disconnecting the updated filter loop line from the line going towards the front of the car. This is not the connector with two tabs on the side that can be pushed and pulled up with special Mercedes pliers. Instead, it is the loop line that goes from the back of the filter, under it, and connects to a line that goes to the engine. It appears to have a small strap on the side of the connector that can be pushed or pulled to release the line's ring from the inside.
