Changing Fuel Filters: 1999 Nissan Altima Guide

If you're looking to change the fuel filter on your 1999 Nissan Altima, you're in the right place. This is a job you can do yourself, but be aware that it can be a little tricky. You'll need to relieve the fuel pressure by pulling the fuel pump fuse, then disconnect the battery and undo the clamps holding the filter in place. Be careful, as you will spill some fuel when you twist the filter off the hoses. You might need to use some elbow grease to remove the hoses, and you may want to have some channel locks to hand.

The fuel filter is part of the fuel pump assembly

To change the fuel filter on a 1999 Nissan Altima, you must first relieve the fuel pressure by pulling the fuel pump fuse in the kicker panel. Then, start the car and let it stall out, and crank it over a few times to ensure all the pressure is out. Next, disconnect the battery and undo the clamps that hold the filter in place. Finally, twist the filter off the hoses and replace it with a new one. Be careful, as you will spill some gas during this process.

Now, onto the fuel filter being part of the fuel pump assembly. In the 2002-2006 Nissan Altima, the fuel filter is part of the fuel pump assembly. This means that the only part that can be replaced in the assembly is the pump itself. So, if you want to change the fuel filter, you need to order and replace the entire fuel pump assembly.

However, some Nissan Altima owners have reported that it is possible to change just the fuel filter portion of the assembly. They have shared instructions on how to do so, which involve taking out the assembly and prying it open to access the fuel filter. This method can be more time-consuming and challenging, but it may be a good option for those who want to save money or enjoy performing their own car maintenance.

It is always recommended to refer to the Nissan Altima Service Manual and take necessary precautions when working on the fuel system.

The fuel filter is located by the firewall on the driver's side

To change the fuel filter on a 1999 Nissan Altima, you will first need to locate it. The fuel filter is located by the firewall on the driver's side.

Once you have located the fuel filter, you will need to relieve the fuel pressure. You can do this by pulling the fuel pump fuse in the kicker panel. Next, start the car and let it stall out. Crank it over a few times to make sure all the pressure is out.

Now, disconnect the battery. Undo the clamps that hold the filter in place, and twist the filter off the hoses. Be careful, as you will spill some gas during this step. Also, be prepared to use some elbow grease, as the hoses are on very tightly.

Finally, you can install the new fuel filter by following these steps in reverse.

Relieve fuel pressure before attempting to change the filter

Relieving fuel pressure is an important safety precaution when changing the fuel filter of your 1999 Nissan Altima. This is because the fuel lines leading to and from the filter will be full of highly pressurised fuel, which can spray out when you disconnect them, posing a serious fire hazard.

To relieve the fuel pressure in your Nissan Altima, start by opening the fuel filler cap on the outside of your car. Loosen the cap until you hear the "hiss" of pressure escaping, but don't remove the cap. Then, locate and remove the fuel pump fuse or relay in your fuse box, which is usually accessible from inside the car, on the driver's side. Start the engine and pull out the fuse or relay—if you've pulled the correct one, the engine should die in a few seconds.

Now, open the hood and disconnect the negative terminal on your car battery to prevent any accidental sparks that might ignite the fuel fumes. You can then proceed to disconnect the fuel lines from the filter. Be ready with a rag or towel to quickly plug the open fuel line to catch any spilling fuel.

It is worth noting that some people skip the process of relieving fuel pressure and simply let the pressurised fuel squirt out when they remove the fuel lines. However, this can be dangerous, and it is recommended to follow the steps outlined above to safely relieve the fuel pressure before attempting to change the filter.

Disconnect the battery and undo the clamps holding the filter

Disconnecting the battery is an important safety step when working on any part of a car's electrical system. Before you begin, make sure you have safety gloves and goggles on. Locate the battery and disconnect it. Now you can proceed to undo the clamps holding the filter.

The fuel filter on a 1999 Nissan Altima is located by the firewall on the driver's side. There are two hoses connecting the filter to the engine, and they are attached with clamps. To undo the clamps, you will need to use a screwdriver or channel locks. Be prepared for some spilled fuel when you twist the hoses off, and have some rags and a small container ready to catch the gas. You will need to use some force to twist the hoses off, so be ready to apply some elbow grease.

It is important to relieve the fuel pressure before attempting to remove the filter. To do this, pull the fuel pump fuse in the kicker panel. Then, start the car and let it stall out. Crank it over a few times to ensure all the pressure is out.

Once the pressure is relieved, you can carefully twist the hoses off and remove the old filter. Be very careful not to spill fuel on any hot engine parts, as this could be a fire hazard.

Now that you have successfully disconnected the battery and undone the clamps holding the filter, you can proceed to install the new fuel filter.

You will spill some gas when changing the filter

When changing the fuel filter on your 1999 Nissan Altima, it's important to be prepared for some gas spillage. This is a common occurrence during this procedure, and there are several steps you can take to manage it effectively. Firstly, you should have a drain pan or container ready to catch any spilled fuel. Position this under the fuel filter before you start.

Next, you'll need to relieve the fuel pressure. This is done by removing the fuel pump fuse or relay, then starting the car and letting it stall out. Crank the engine over a few times to ensure all the pressure is released.

Now, disconnect the battery and undo the clamps holding the fuel filter in place. You will likely need to use some elbow grease to twist the filter off the hoses, and this is when you will encounter the gas spill. Be cautious and use a screwdriver or pliers to carefully pry the lines off. You may want to use hose-removing pliers or a hose-separation tool to make this process easier.

It's important to be prepared for the gas spill and to have the necessary safety equipment. Wear nitrile gloves to protect your hands from the gasoline, and make sure you are working in a well-ventilated area. Keep a Class B fire extinguisher nearby as a safety precaution.

By following these steps, you can effectively manage any gas spillage that occurs when changing the fuel filter on your 1999 Nissan Altima.
