Changing Fuel Filter On 2004 Nissan Quest: Step-By-Step Guide

The fuel filter in a 2004 Nissan Quest is situated inside the gas tank, and is part of the fuel pump assembly. The fuel filter should be replaced approximately every 30,000 miles to prevent performance issues. The procedure for replacing the fuel filter involves disconnecting the negative battery cable, draining the fuel tank, detaching the fuel pump relay, relieving the pressure in the fuel lines, removing the exhaust pipe, parking brake cables, and fuel tank shield, detaching the electrical connectors and fuel hose from the fuel pump assembly, removing the fuel filter, installing a new fuel filter, and reattaching the various components.

The fuel filter is part of the fuel pump assembly

• Disconnect the negative battery cable with a socket wrench.
• Drain the fuel from the fuel tank into an approved container.
• Remove the cover from the relay panel on the left side of the engine compartment.
• Detach the fuel pump relay from the relay panel.
• Start the engine and let it stall. Crank the engine twice to ensure the pressure in the fuel lines is relieved.
• Turn the ignition switch off and replace the fuel pump relay.
• Remove the centre exhaust pipe with a socket wrench, without disconnecting the mufflers.
• Disconnect the parking brake cables and their mounting brackets with a socket wrench. Push the cables out of the way to access the fuel tank.
• Remove the shield from the fuel tank with a socket wrench.
• Detach the evaporative emissions hose, recirculation hose, and fuel filler hose from the fuel tank.
• Support the fuel tank with a jack and disconnect the mounting straps.
• Lower the fuel tank with the jack to access the fuel pump assembly.
• Detach the electrical connectors and fuel hose from the fuel pump assembly.
• Remove the fuel tank from the vehicle and set it aside.
• Turn the locking ring on the fuel pump counter-clockwise with a socket wrench and tool J-16214.
• Remove the fuel filter from the fuel pump assembly.
• Install the new fuel filter onto the fuel pump assembly.
• Fasten the locking ring onto the fuel pump assembly and turn it clockwise with a socket wrench and tool J-16214.
• Install the fuel tank and tighten the mounting straps to 31 ft. lbs. with a socket wrench.
• Fill the fuel tank with fuel.
• Turn the ignition switch on, pressurising the fuel system.
• Correct any fuel leaks and start the engine.
• Allow the engine to idle and correct any additional fuel leaks.

It is important to note that the fuel filter is located inside the fuel tank, so the fuel tank must be dropped to access the fuel pump and filter.

It is recommended to replace the fuel filter approximately every 30,000 miles to prevent performance issues and ensure optimal fuel combustion.

Drain the fuel from the fuel tank

To drain the fuel from the fuel tank of a 2004 Nissan Quest, you will need a container approved for holding gasoline. This is because the first step is to drain the fuel from the tank into this container.

Before you begin, it is important to note that you should never smoke or have any kind of flame near gasoline. In addition, always wear safety goggles and gloves when handling gasoline. Now, to begin, locate the relay panel on the left side of the engine compartment. Using a socket wrench, remove the cover from the relay panel and then detach the fuel pump relay from the panel.

Next, you will need to start the engine and allow it to stall. Crank the engine twice to ensure that you have relieved the pressure in the fuel lines. Finally, turn the ignition switch to the off position and replace the fuel pump relay.

Access the fuel tank by removing the centre exhaust pipe

To access the fuel tank of a 2004 Nissan Quest, you will need to remove the centre exhaust pipe. Here is a step-by-step guide on how to do this:

Firstly, ensure you have the necessary tools, including a socket wrench. Then, locate the centre exhaust pipe. You will need to remove this without disconnecting the mufflers, so take care not to disturb them. Using your socket wrench, loosen and remove the bolts holding the centre exhaust pipe in place. Once all the bolts are removed, carefully lift the pipe away from the vehicle. Set it aside in a safe place.

Now you should be able to see and access the fuel tank. Before proceeding, it is important to note that the fuel filter is positioned within the fuel tank and is not designed to be serviced or replaced separately. If you need to replace the fuel filter, you will need to replace the entire fuel pump assembly.

To continue with fuel tank removal, you will next need to disconnect the parking brake cables and their mounting brackets. Again, use your socket wrench to loosen and remove the bolts holding these in place. Push the cables out of the way to give yourself clear access to the fuel tank.

At this point, you will be able to see the fuel tank shield. Remove this with your socket wrench, followed by the evaporative emissions hose, recirculation hose, and fuel filler hose. Detach these hoses from the fuel tank to complete this step.

Now you are ready to support the fuel tank with a jack and begin the process of detaching it from the vehicle.

Detach the electrical connectors and fuel hose from the fuel pump assembly

To detach the electrical connectors and fuel hose from the fuel pump assembly, you will need a socket wrench.

First, locate the electrical connectors and the fuel hose. These should be clearly visible, attached to the fuel pump assembly. Once you have identified them, use the socket wrench to loosen the connectors and detach the fuel hose. Be sure to do this carefully, as the electrical connectors and fuel hose may be delicate.

Set the detached parts aside, ensuring they are placed in a safe area where they will not be damaged or disturbed. You may want to label or mark them clearly to avoid any confusion when reassembling the fuel pump.

With the electrical connectors and fuel hose removed, you will now have access to the fuel pump assembly and can continue with the next steps of replacing the fuel filter on your 2004 Nissan Quest.

Remove the fuel filter from the fuel pump assembly

To remove the fuel filter from the fuel pump assembly of a 2004 Nissan Quest, you will first need to disconnect the negative battery cable with a socket wrench. Drain the fuel from the fuel tank into an approved gasoline container. Remove the cover from the relay panel on the left side of the engine compartment and detach the fuel pump relay from the relay panel.

Next, start the engine and let it stall. Crank the engine a further two times to relieve the pressure in the fuel lines. Turn the ignition switch off and replace the fuel pump relay.

Now, remove the centre exhaust pipe with a socket wrench, without disconnecting the mufflers. Disconnect the parking brake cables and their mounting brackets with a socket wrench and move the cables out of the way to access the fuel tank.

Remove the shield from the fuel tank with a socket wrench. Detach the evaporative emissions hose, recirculation hose, and fuel filler hose from the fuel tank. Support the fuel tank with a jack and disconnect the mounting straps. Lower the fuel tank with the jack to access the fuel pump assembly.

Detach the electrical connectors and fuel hose from the fuel pump assembly. Now, you can remove the fuel tank from the vehicle.

Turn the locking ring on the fuel pump counter-clockwise with a socket wrench and tool J-16214. Finally, remove the fuel filter from the fuel pump assembly.
