Replacing 1999 Grand Am Fuel Filter: Step-By-Step Guide

The 1999 Pontiac Grand Am is a mid-size car produced by Pontiac. The fuel filter on a 1999 Grand Am is located between the tank and the bumper near the charcoal canister, or in the fuel line between the fuel tank and the engine. To change the fuel filter, you will need to depressurise the fuel line, remove the bolt holding the fuel filter brace, and unscrew the nut on the side of the fuel filter. You will then need to clean the gas off the fuel lines, attach the new fuel filter with the brace, and re-pressurise the fuel line.

The fuel filter is located between the tank and bumper, near the charcoal canister

To change the fuel filter on a 1999 Grand Am, you will first need to locate it. The fuel filter is located between the tank and the bumper, near the charcoal canister.

Now, let's go through the process of changing the fuel filter step-by-step. First, you will need to raise the car and locate the fuel filter under the rear of the car on the driver's side. Make sure you have the necessary tools and safety equipment, such as eye protection, before beginning.

The next step is to depressurize the fuel line to prevent gas from spraying out. Open the hood and locate the housing for the fuses and relays. Remove the cover and find the fuel pump relay, which may be labelled on the inside of the fuse housing diagram. Remove the fuel pump relay and turn off the car.

Now, you can begin to remove the fuel filter. Place a drip pan or a rag underneath the fuel filter to catch any gas that may spill. Remove the bolt holding the fuel filter brace in place, as well as the nut on the left side of the fuel filter facing towards the engine. If the fuel filter is old, it may be difficult to unscrew, so you may need to use a second wrench to hold it in place.

Once the first side is loose, move to the other end of the fuel filter and push in the two tabs on the plastic piece to pull the filter off. More gas will spill at this point, so be cautious.

Now, you can install the new fuel filter. First, clean the gas off the two fuel lines with a rag. Put the brace on the new fuel filter and screw it onto the fuel line nearest to the engine, ensuring it is tight to prevent leaks. Then, attach the other end by pushing the fuel line onto the filter until you hear a small click.

Finally, reattach the brace to the frame by screwing the bolt back in. Close the housing for the fuses and relays, shut the hood, and reinsert the fuel pump relay. Turn the key in the ignition to re-pressurize the fuel line, but do not turn on the engine. Check for leaks around the fuel filter, and if none are present, start the engine and let it idle for a few seconds. Turn off the engine and check the fuel filter one last time for leaks. If there are no leaks, you have successfully changed your fuel filter!

De-pressurise the fuel line to prevent gas shooting out

De-pressurising the fuel line of your 1999 Grand Am is an essential step when changing the fuel filter. This will prevent gas from shooting out and causing injury or damage.

Firstly, locate the fuel pump relay in the fuse box under the hood of your car. With the engine running, carefully take out the fuel pump relay. The engine will continue to run for a short time, so be prepared for this. Let the engine run until it begins to slow and eventually stop. You may then crank the engine a few more times to ensure that all pressure is released.

Alternatively, you can simply wrap a rag around the fuel line and disconnect it from the rail. This method will result in a quick squirt of fuel, so be sure to cover the line with the rag to catch any escaping gas.

Another option is to look for a test port on the rail. This will look like a valve stem on a tire and can be used to relieve pressure in the same way as a tire valve.

Whichever method you choose, always exercise caution when working with fuel lines and be sure to have adequate ventilation to avoid inhaling fumes.

Remove bolt holding the fuel filter brace

To remove the bolt holding the fuel filter brace, you will need to locate the bolt. It is situated on the driver's side of the car, under the rear, approximately where the cardboard box is located. Once you have found the bolt, use the appropriate tool to remove it. Make sure to put the bolt somewhere safe so that it is not lost.

The bolt holds the fuel filter brace in place, so once it is removed, you will be able to access the fuel filter. Before removing the fuel filter, it is important to depressurise the fuel line to prevent gas from shooting out and covering your face. To do this, locate the housing for your fuses and relays, remove the cover, and pull out the fuel pump relay. This will cause your engine to stall and stop running. Turn off your car and remove the key before continuing.

Now, you can begin to remove the fuel filter. On the left side of the fuel filter, there is a nut that must be unscrewed. If the fuel filter has not been changed in a while, it may be difficult to remove. In this case, use a second wrench to hold the fuel filter in place while unscrewing the nut. Wear eye protection, as dirt may fall loose and get into your eyes. When the line is unscrewed, some gas will come out of the line and the filter, so have something ready to catch the gas and prevent it from spilling onto the ground or yourself.

The other end of the fuel filter can be removed by pushing in the two tabs on the plastic piece and pulling the filter off. More gas will come out once this end is removed, so be sure to have a drip pan ready. With the old fuel filter removed, you can now install the new fuel filter.

Unscrew the nut on the left side of the fuel filter

To remove the fuel filter from your 1999 Pontiac Grand Am, you will need to first locate the fuel filter. It is situated on the driver's side, under the rear of the car. Once you have found it, you can begin the process of removal.

The left side of the fuel filter is the end that faces towards the engine. On this side, there is a nut that must be unscrewed. If the fuel filter hasn't been changed in a long time, it may be difficult to remove. In this case, use a second wrench to hold the fuel filter in place while you work.

As you unscrew the nut, some dirt may fall from the bottom of the car, so it is important to wear eye protection. When the line is unscrewed, some fuel will escape from the line and the filter, so be sure to have something to catch it and prevent it from spilling onto the ground or yourself.

Now that the nut on the left side of the fuel filter has been successfully unscrewed, you can move on to removing the other end of the fuel filter. This step is relatively straightforward; simply push in the two tabs on the plastic piece and pull the filter off. Again, more fuel will be released, so be prepared to catch it.

With both ends of the fuel filter disconnected, the old fuel filter can now be completely removed from the car. Before installing the new fuel filter, be sure to clean any residual fuel from the two fuel lines with a rag.

Clean the gas off the fuel lines before putting on the new fuel filter

To clean the gas off the fuel lines before putting on the new fuel filter, follow these steps:

Firstly, locate the fuel lines. In the 1999 Pontiac Grand Am, the fuel filter is located between the fuel tank and the bumper, near the charcoal canister, or next to the fuel tank. The fuel tank is located at the rear of the car, on the driver's side.

Once you have located the fuel lines, disconnect them from other parts of the fuel system. This will involve loosening clamps and disconnecting hoses and pipes. Be sure to have a catch basin or container ready to collect any fuel or cleaner that may spill.

Next, flush the fuel lines with a suitable cleaner. A gas line cleaner is recommended, but if unavailable, you can use rubbing alcohol as its composition will help clear the fuel line. Inject or pour the cleaner into the fuel lines and use compressed air to clean them.

After flushing the fuel lines, be sure to clean the fuel filler hose as well. Spray water into the filler hose until the water runs clear, then pour rubbing alcohol through it until the liquid coming out is clear.

Finally, reconnect the fuel lines and hoses, ensuring that all connections are secure and locked to prevent leaks.

Remember to exercise caution when working with fuel and cleaners, and ensure there are no fire starters nearby. It is recommended to disconnect the battery terminals before beginning any work on the fuel system.
