Drain the fuel tank
To drain the fuel tank of a Nissan Sentra 2001, follow these steps:
Firstly, open the fuel filler lid and the filler cap to release the pressure inside the fuel tank. Release the fuel pressure from the fuel lines. Check the fuel level with the vehicle on a level surface. If the fuel gauge indicates more than half full, you will need to drain the fuel from the tank until it reaches or is below the halfway mark.
There are a few ways to drain the fuel. One method is to use a pump or siphon setup to remove the fuel. You can purchase a plastic siphoning kit from an auto parts store. Remove the fuel cap and insert the siphon hose through the narrow opening. You may need to wiggle the hose to get it through. Alternatively, you can disconnect the filler hose from the filler tube and insert the siphon hose into it. Be careful to keep the hose below the tank so that the fuel will begin to siphon.
Another method is to remove the fuel tank and drain it. To do this, disconnect the rear cables and the return line from the filler hose. Remove the filler hose and the vent hose from the fuel tank. Support the center of the fuel tank with a jack and secure it with a piece of wood. Remove the fuel tank mounting bands. Lower the jack carefully and remove the fuel tank.
It is important to note that working on the fuel system can be dangerous. Always refer to the Nissan Sentra Service Manual and follow "General Precautions" when performing these tasks. Ensure you cap or plug openings to prevent fluid from spilling. Always work in a well-ventilated area to prevent fumes from localizing.

Disconnect rear cables
To disconnect the rear cables when removing the fuel tank in a 2001 Nissan Sentra, follow these steps:
First, open the fuel filler lid and the filler cap to release the pressure inside the fuel tank. Release the fuel pressure from the fuel lines. Check the fuel level with the vehicle on a level surface. If there is more than half a tank of fuel, drain it until the fuel gauge reads half a tank or below.
Next, disconnect the rear cables and set them aside. Refer to the Nissan Sentra Service Manual for the relevant exploded view diagram, either BR-42 (Drum brake) or PB-9 (Disc brake).
After disconnecting the rear cables, you can continue with the fuel tank removal process. This includes disconnecting the return line from the filler hose, removing the fuel filler hose, and disconnecting the vent hose from the fuel tank.
Always refer to the Nissan Sentra Service Manual for specific instructions and safety precautions when working on the fuel system.

Remove fuel filler hose
To remove the fuel filler hose in a 2001 Nissan Sentra, begin by opening the fuel filler lid and the filler cap to release the pressure inside the fuel tank. Release the fuel pressure from the fuel lines. Check the fuel level with the vehicle on a level surface. If the fuel gauge indicates more than half full, drain the fuel from the tank until it is at or below half full.
Next, disconnect the return line from the filler hose. Now, you can remove the fuel filler hose. Disconnect the vent hose from the fuel tank.
It is important to note that when removing components such as hoses, tubes, and lines, openings should be capped or plugged to prevent fluid from spilling.
If you are looking to drain the fuel tank, there are two options. The first is to use a pump or a siphon to remove the fuel. The second option is to remove the tank and drain it. However, if there is still a lot of fuel in the tank, this will be difficult due to the weight.

Secure the fuel tank
To secure the fuel tank of a 2001 Nissan Sentra, you must follow a careful procedure. Firstly, open the fuel filler lid and cap, and release the pressure inside the fuel tank. It is important to refer to the work procedure outlined in EC-143. Check the fuel level and ensure it is no more than half full; if it is, drain the fuel until it reaches the halfway mark.
Next, disconnect the rear cables and set them aside. Disconnect the return line from the filler hose and remove the fuel filler hose. Disconnect the vent hose from the fuel tank. Now, support the centre of the fuel tank with a suitable jack, and secure the tank to the jack. It is important to also support the fuel tank with a piece of wood, as the tank may be unstable due to its shape.
Remove the fuel tank mounting bands, and carefully lower the jack to remove the fuel tank, ensuring you are holding the tank securely. Finally, remove the lock ring for the fuel level sensor unit, the fuel filter, and the fuel pump assembly by turning it counterclockwise.
It is crucial to always secure the fuel tank during this process, as per the Nissan Sentra Service Manual.

Remove fuel tank mounting bands
To remove the fuel tank mounting bands of a 2001 Nissan Sentra, you must first perform a series of preparatory steps. Begin by opening the fuel filler lid and the filler cap to release the pressure inside the fuel tank. Next, release the fuel pressure from the fuel lines by referring to the specified work procedure (EC-143). It is important to check the fuel level with the vehicle on a level surface. If the fuel gauge indicates more than half full, drain the fuel from the tank until it reaches or falls below the halfway mark. This can be done by inserting fuel tubing into the filler tube and tank to facilitate drainage.
Once the fuel level is safe, proceed by disconnecting the rear cables and positioning them aside. Disconnect the return line from the filler hose and then remove the filler hose itself. Disconnect the vent hose from the fuel tank. At this point, you should support the centre of the fuel tank with a suitable jack and secure the tank with a piece of wood. The fuel tank may be unstable due to its shape, so ensure it is secured at all times.
Now, you can remove the fuel tank mounting bands (RH/LH). Lower the jack carefully while holding the fuel tank by hand. Again, be cautious as the fuel tank may be unstable. After removing the mounting bands, you can proceed to remove the lock ring for the fuel level sensor unit, fuel filter, and fuel pump assembly if necessary. Remember to follow safety guidelines and secure the fuel tank throughout the process.
