However, there's a critical safety precaution: Fuel is flammable and potentially explosive. You MUST disconnect the negative (-) battery terminal before beginning any work near the fuel system.
Here's a general outline; the exact location and process will vary slightly depending on the engine (e.g., 3.7L, 4.7L, 5.9L) and whether you have a 4x4 or 2x4 model. You should consult a repair manual specific to your Durango's engine and drivetrain. A Haynes or Chilton manual is a good investment for this type of work.
General Steps (Consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery terminal. Allow several minutes for the system to fully discharge any residual electricity.
2. Locate the Fuel Filter: This is often found near the fuel tank, sometimes under the vehicle. Your repair manual will show the exact location.
3. Prepare Tools: You'll need wrenches (likely a socket set) to remove the fuel lines, and possibly pliers or a fuel line disconnect tool. Have rags or shop towels ready to absorb any spilled fuel. You'll also need a container to catch the fuel that will drain from the lines.
4. Loosen Fuel Lines: Carefully loosen the clamps holding the fuel lines to the filter. Be ready for fuel to leak out (this is why you need a container and why disconnecting the battery is so important!). Use a rag to catch any drips. Some fuel lines have quick-disconnect fittings; others require loosening clamps.
5. Remove Fuel Filter: Once the lines are disconnected, carefully remove the fuel filter.
6. Install New Filter: Make sure the new filter is oriented correctly (often marked with an arrow indicating fuel flow). This is crucial; installing it backward can damage the fuel pump.
7. Reconnect Fuel Lines: Carefully reconnect the fuel lines, ensuring the clamps are securely tightened.
8. Reconnect Battery: Reconnect the negative battery terminal.
9. Prime the Fuel System (Possibly): Some vehicles require priming the fuel system after a filter change. This might involve turning the ignition key to the "on" position for a few seconds several times, allowing the pump to fill the lines. Consult your repair manual for your specific vehicle.
10. Start the Engine: Start the engine and check for leaks around the fuel filter and fuel lines. Let the engine run for a few minutes to ensure the new filter is working correctly.
Important Considerations:
* Fuel Pressure: The fuel system is under pressure. Releasing this pressure incorrectly can lead to fuel spraying. Your repair manual will guide you through this process safely. Some vehicles have a fuel pressure release valve.
* Fuel Type: Use the correct fuel type for your engine.
* Repair Manual: A repair manual is essential for detailed instructions and diagrams. Trying this without a proper manual is strongly discouraged.
If you're not comfortable performing this repair yourself, take your Durango to a qualified mechanic. Working on the fuel system is potentially dangerous if not done correctly.
