Introduction

This tutorial will guide you through the process of changing the diesel fuel filter on a Mercedes Sprinter V6 3.0 Liter model from 2013 to 2018. Performing this maintenance task can help improve engine performance and fuel efficiency while saving you money on dealer services.

Step 1: Gather Your Tools and Materials

Before you start the fuel filter change, make sure you have the following tools and materials ready:

• New diesel fuel filter compatible with your Sprinter model
• Wrench set (or socket set)
• Pliers
• Fuel line disconnect tool (if necessary)
• Clean rag or towel
• Safety glasses
• Gloves

Tip: Always use genuine or high-quality parts to ensure optimal performance.

Step 2: Locate the Fuel Filter

• The fuel filter is typically located underneath the vehicle, near the fuel tank.
• You may need to lift the vehicle using a jack and secure it with jack stands for easier access.

Safety Reminder: Always ensure the vehicle is stable before working underneath it.

Step 3: Release Fuel Pressure

• Before removing the fuel filter, you must release the fuel system pressure to prevent fuel spray.
• Locate the fuel pump relay in the fuse box and remove it.
• Start the engine and let it run until it stalls; this indicates that the pressure has been relieved.

Step 4: Disconnect the Fuel Lines

• Use the fuel line disconnect tool to carefully detach the fuel lines from the old filter.
• Be prepared for some fuel spillage; have a rag handy to catch any excess fuel.

Common Pitfall: Avoid using excessive force when disconnecting the fuel lines, as this can damage fittings.

Step 5: Remove the Old Fuel Filter

• Using your wrench or socket, unscrew the mounting bolts holding the old fuel filter.
• Carefully remove the filter from its bracket.

Step 6: Install the New Fuel Filter

• Position the new fuel filter in the bracket, ensuring the flow direction matches the old filter (usually indicated by an arrow).
• Secure it in place by tightening the mounting bolts.

Step 7: Reconnect the Fuel Lines

• Reattach the fuel lines to the new filter, ensuring they click into place securely.
• Double-check that all connections are tight to prevent leaks.

Step 8: Restore Fuel System Pressure

• Replace the fuel pump relay in the fuse box.
• Turn the ignition key to the "ON" position for a few seconds without starting the engine to allow the fuel system to pressurize.
• Check for any leaks around the new fuel filter.

Changing the diesel fuel filter on your Mercedes Sprinter can be a straightforward DIY task with the right tools and steps.
