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

The fuel pump in a Nissan Murano is located inside the fuel tank, which is accessible by removing the rear seat bottom and locating the access panels on either side. The fuel pump replacement cost for a Nissan Murano ranges from $1,031 to $1,175, with labour costs estimated between $112 and $142, and parts priced between $919 and $1,034. It is a complex process that requires expertise and caution to prevent the risk of fire. Therefore, it is recommended to seek professional assistance for fuel pump replacement.

The fuel pump is located under the rear seat cushion

To replace the fuel pump on a Nissan Murano, you will first need to locate it under the rear seat cushion. This is accessible by removing the rear seat bottom. Once the seat is removed, you will find two access panels, one on each side. As the Nissan Murano has a saddle-type tank, there are two fuel level sensors and two fuel pickups. You can access these through the access ports. The fuel pump is located under the driver-side panel.

To access the fuel pump, you will need to remove the rear seat cushion. This will involve unscrewing or unclipping the cushion from the base of the seat. Once the cushion is removed, you will be able to see the access panels. The fuel pump is located under the driver-side panel, so you will need to remove this panel to access the pump.

The fuel pump is an important component of your vehicle, delivering fuel from the tank to the fuel injectors. It is an electric pump, mounted inside the fuel tank. By being located inside the tank and submerged in the fuel, the pump is kept cool, reducing the risk of fire.

Replacing the fuel pump on a Nissan Murano is a complex task and it is recommended that you seek the help of a professional mechanic unless you have significant auto repair experience.

Disconnect the battery to reduce the chance of a fire

Disconnecting the battery is the first step in replacing the fuel pump on a Nissan Murano. This is a crucial safety precaution to reduce the chance of a fire. Working with the fuel system can be dangerous, and it is essential to take all necessary precautions to prevent accidents.

Disconnecting the battery will break the electrical circuit, reducing the risk of sparks or electrical current igniting any fuel vapours that may be present. Sparks or electrical current can easily ignite fuel vapours, leading to a fire or explosion. By disconnecting the battery, you eliminate this risk and create a safer working environment.

It is also important to work in a well-ventilated area when performing this task. Fuel vapours are toxic and can cause serious health issues if inhaled. Working in a well-ventilated area will help dissipate the vapours and reduce the risk of inhalation. Additionally, having proper ventilation will also reduce the risk of vapour buildup, which could lead to an explosion if ignited.

Before beginning any work on the fuel pump, it is crucial to allow the engine to cool down completely. A hot engine can ignite fuel vapours more easily, increasing the risk of a fire. Always make sure to give the engine sufficient time to cool down before starting any repairs or maintenance involving the fuel system.

By taking these precautions, such as disconnecting the battery, working in a well-ventilated area, and allowing the engine to cool down, you can significantly reduce the chance of a fire when replacing the fuel pump on your Nissan Murano.

For pumps inside the fuel tank, remove the access cover

To replace the fuel pump on a Nissan Murano, you'll first need to locate the pump. In the 2003 model, the fuel pump is inside the fuel tank and can be accessed from under the rear seat cushion.

• Remove the rear seat bottom to locate the access panels on either side.
• Since the Nissan Murano has a saddle-type tank, there will be two fuel level sensors and two fuel pickups.
• The fuel pump is located under the driver-side access panel.
• Remove the access panel by unscrewing the bolts or fasteners holding it in place. Be careful not to lose any screws or fasteners during this process.
• With the access panel removed, you should now be able to see the fuel pump and the pre-pump filter screen.
• Before proceeding, it is essential to disconnect the battery to reduce the risk of fire.
• Carefully remove the old fuel pump and the pre-pump filter screen. You may need to drain some fuel before completely removing the old pump.
• Install the new fuel pump and filter screen, ensuring they are securely connected.
• Reattach the access panel and tighten the screws or fasteners securely.
• Reconnect the battery and ensure that all components are securely connected.

By following these steps, you can safely and effectively replace the fuel pump on a Nissan Murano with an internal fuel tank.

Replace the pump and pre-pump filter screen

To replace the fuel pump and pre-pump filter screen on a Nissan Murano, you will first need to disconnect the battery to reduce the chance of a fire. Next, you will need to access the pump. On the 2003 model, this can be done by removing the rear seat bottom and locating the access panels on either side. The fuel pump is located under the driver-side panel. Once you have accessed the pump, you can replace it and the pre-pump filter screen.

It is important to note that working with the fuel system can be dangerous, so it is recommended to let a repair shop handle this job unless you are very experienced in auto repair. Additionally, make sure to take all necessary precautions to prevent fires.

Check for fuel leaks and ensure the problem is solved

To check for fuel leaks and ensure the problem is solved, you must first identify the source of the leak. Fuel leaks can be dangerous and lead to a fire or explosion, so it is important to address them promptly.

Begin by inspecting the ground underneath the gas tank to look for any signs of gasoline pooling. Next, examine the tank itself to pinpoint the source of the leak. This will help determine if the tank can be repaired or needs to be replaced. If the tank is corroded or has a puncture, it may need to be replaced entirely.

If the leak is coming from the fuel lines, this may require a separate repair. Fuel lines can be accessed by removing the rear seat bottom, where you will find two access panels, one on each side. The fuel pump is typically located under the driver-side panel.

Once the origin of the leak has been identified and repaired, it is important to test the system to ensure the problem has been resolved. A mechanic can help with this process, which may involve checking fuel pressure and inspecting fuel lines, hoses, and tubes for any signs of clogging or damage.
