Replacing Fuel Pump In Nissan Murano: Step-By-Step Guide

Changing the fuel pump on a 2004 Nissan Murano is a complex task. The fuel pump is located in the tank, which can be accessed by removing the rear seat bottom. Underneath, there are two access panels, one on each side, which lead to the fuel pump. Before starting, it is important to relieve the fuel pressure to the tank and ensure the fuel level is below a quarter of a tank. No specialty tools are required for this task.

Ensure your fuel tank is under 1/4 full.

It is important to ensure your fuel tank is under 1/4 full when changing the fuel pump on a 2004 Nissan Murano. This is because the access panel for the fuel pump is located beneath the rear seats. By ensuring your fuel tank is under 1/4 full, you will have easy access to the pump and can avoid the risk of fuel spillage.

To ensure your fuel tank is under 1/4 full, you can either drive your car until the fuel level reaches below 1/4 or, if you need to replace the fuel pump immediately, you can carefully siphon the fuel from the tank into a safe container. Remember to take appropriate safety measures when handling fuel, such as wearing protective gloves and eye gear, and ensuring the area is well-ventilated.

Once your fuel tank is under 1/4 full, you can proceed to remove the rear seats to access the fuel pump. This process may vary depending on your specific model of Nissan Murano, so it is recommended to refer to your owner's manual or seek guidance from a qualified mechanic.

Additionally, before attempting any service on the fuel system, it is crucial to relieve the fuel pressure to the tank. This can be done by following the standard safety procedures outlined in your repair manual or by a professional.

Relieve the fuel pressure to the tank.

To relieve the fuel pressure to the tank of your 2004 Nissan Murano, follow these steps:

Firstly, ensure your fuel tank is no more than a quarter full. This is an important safety precaution as it reduces the risk of overflowing fuel when you relieve the pressure.

Next, locate the fuel pump access panel. This is situated beneath the rear seats of the car. Remove the rear seats to grant yourself easy access to the fuel pump.

Now you can relieve the fuel pressure. This is a delicate procedure, so be cautious and take your time. Ensure you are wearing the correct safety equipment, including gloves and eye protection. Once you are ready, carefully relieve the fuel pressure to the tank.

After completing these steps, you can continue with the fuel pump replacement, safe in the knowledge that you have relieved the fuel pressure to the tank of your 2004 Nissan Murano.

Remove rear seats to access the fuel pump.

To remove the rear seats of a Nissan Murano to access the fuel pump, follow these steps:

First, ensure that the fuel pressure to the tank is relieved before attempting any service on the fuel system. It is also important to ensure that the fuel level is below a quarter of a tank prior to the service.

Now, to remove the rear seats, there are a few different techniques depending on the year and series of your Nissan Murano.

If your rear seat is mounted with a bolt system, you will need to unscrew the two nuts at the back of the seat, accessible from the trunk, using a Torx bit. Then, unscrew the two nuts at the front of the seat, located under the seat in the passenger footwell.

If your rear seat has a clip system, you will need to locate the clips under the seat. These clips usually consist of a plastic portion and a metal iron. To release them, press on the plastic part with a screwdriver and pull the metal part. If this technique does not work, simply pulling on the clips may be enough to release them.

Finally, if your rear seat has a folding system with bolts only at the front, tilt the seat forward to access the Torx nuts that hold it to the chassis. Once these nuts are unscrewed, you can remove the rear seat.

By following these steps, you will be able to remove the rear seats of your Nissan Murano and access the fuel pump for replacement or service.

Disconnect the old fuel pump.

Disconnecting the old fuel pump on a 2004 Nissan Murano is a complex task that requires careful attention to safety precautions. Here is a step-by-step guide to help you through the process:

Step 1: Relieve Fuel Pressure

Before starting any work on the fuel system, it is crucial to relieve the fuel pressure in the tank. This step is essential for safety and should not be skipped.

Step 2: Remove Rear Seats

The access panel for the fuel pump is located beneath the rear seats. Remove the rear seat bottom to access the fuel pump compartment.

Step 3: Locate the Fuel Pump

Once you have removed the rear seat, you will see two access panels, one on each side. The fuel pump is located under the driver-side panel.

Step 4: Disconnect the Fuel Pump

With the fuel pump compartment accessible, you can now disconnect the old fuel pump. This process involves unplugging electrical connectors and removing any mounting hardware that secures the fuel pump in place. Work carefully and methodically, making note of any parts or screws you remove to ensure proper reassembly.

Step 5: Prepare for Fumes

Working in an enclosed space with gasoline fumes can be dangerous. Ensure the workspace is well-ventilated, and consider using a fan to circulate fresh air. If possible, wear a respirator or a mask rated for organic vapours to avoid inhaling fumes.

Step 6: Spark Prevention

When working with gasoline and its fumes, it is crucial to prevent any potential sources of ignition. Do not smoke, and ensure all power tools and equipment are spark-free. Take extra care to avoid creating any sparks that could cause an explosion.

By following these steps, you will be able to safely disconnect the old fuel pump on your 2004 Nissan Murano. Remember to work carefully and consult a professional mechanic if you have any concerns or uncertainties during the process.

Connect the new fuel pump

To connect the new fuel pump for your 2004 Nissan Murano, follow these steps:

Firstly, ensure you have relieved the fuel pressure to the tank and that your fuel level is below a quarter of a tank before starting. This is important for safety reasons. Next, locate the access panel for the fuel pump, which is situated beneath the rear seats. Remove the rear seats to gain easy access to the pump.

Now, you can begin the process of connecting the new fuel pump. Ensure that you have purchased the correct fuel pump for your Nissan Murano, taking into account the model year and engine specifications. Once you have the correct pump, carefully align it with the fuel pump mounting in the fuel tank. You may need to refer to a repair manual for the exact positioning, as it is crucial that the pump is installed correctly and securely.

Proceed to connect the electrical connectors to the new fuel pump. Ensure that all connections are secure and that there is no damage to the wiring. Once the connections are secure, you can mount the new fuel pump in place. Secure the pump according to the manufacturer's instructions and ensure that it is firmly in place.

Finally, re-install the rear seats and any other components that were removed to access the fuel pump. Ensure that all connections are secure and that there are no loose wires or components. Now, you can fill your fuel tank to the desired level and start the engine to test the new fuel pump. Ensure that there are no leaks and that the pump is functioning correctly. If you notice any issues, such as unusual noises or fuel leaks, stop the engine immediately and re-inspect your work.
