Replacing The Fuel Filter In A 1999 Saturn: Step-By-Step Guide

Changing the fuel filter on a 1999 Saturn SL2 is a simple repair that can be done without advanced training. The fuel filter is located under the car, to the backside, near the rear wheels. The first step is to remove the fuel pump fuse, which is located inside the vehicle on the passenger side. Next, start the car and let it idle until it stalls to drain the fuel from the system. Then, locate the Schrader valve under the hood, remove the screw on the black cap, and depress the valve. This will depressurize the fuel system. Jack up the rear of the car and locate the original fuel filter. The rest of the process involves removing bolts, disconnecting and reconnecting tubes and fuel lines, and reattaching the bracket.

Remove the fuel pump fuse

To remove the fuel pump fuse on a 1999 Saturn, follow these steps:

First, locate the fuse box. For a 1999 Saturn, the fuse box is located inside the vehicle.

Next, identify the fuel pump fuse. It will be labelled clearly and should be easy to spot.

Once you have located the fuel pump fuse, remove it by pulling it straight out of the fuse box. Be careful not to touch any of the other fuses or components in the fuse box, as this could cause electrical problems.

If the fuse is difficult to remove, you may need to use a small screwdriver or other tool to gently pry it out. Be careful not to damage the fuse or the fuse box.

Now that you have removed the fuel pump fuse, you can replace it with a new one or clean and inspect the old one. If you are replacing it, make sure to get an exact replacement and insert it into the fuse box firmly until it is fully seated.

Finally, before starting your car, make sure to check that all fuses are secure and that there are no loose wires or other issues in the fuse box. This will help prevent electrical problems and ensure your car runs smoothly.

Drain the fuel from the system

To drain the fuel from the system of a 1999 Saturn, you must first remove the fuel pump fuse, which is located inside the vehicle on the passenger side. This will differ depending on the model of your Saturn. For example, if you have an S-Series, the fuse box is located inside the vehicle. However, if you have an SL2, the fuse box is on the passenger side.

Once you have located the fuel pump fuse, remove it and start the car. Let the engine run for a few minutes until the car stalls, as this will allow the fuel to drain from the system. It is important to note that you should only start your car for a short period of time, as you do not want to run the car without fuel for an extended period.

After the car has stalled, you can then locate the Schrader valve under the hood. Remove the screw-on black cap and depress the valve. Be sure to have a rag handy to catch any fuel that may escape. At this point, your fuel system will be depressurized, and you can move on to the next step of changing the fuel filter.

It is important to exercise caution when working with fuel and ensure that you are in a well-ventilated area to avoid inhaling fumes. Additionally, have a shop cloth and a container ready to capture any spilled fuel during the process.

Disconnect the fuel filter

Disconnecting the fuel filter on a 1999 Saturn SL2 is a straightforward process, but it requires careful attention to safety precautions and a few basic tools. Here is a detailed, step-by-step guide to help you through the process:

Prepare Your Vehicle:

Before beginning any work, it is crucial to relieve the fuel system pressure and raise and support the vehicle securely. Refer to your vehicle's specific instructions for relieving fuel pressure and raising the car safely. Additionally, keep a shop cloth and an approved fuel container ready to capture any spilled fuel during the process.

Locate the Fuel Filter:

The fuel filter on a 1999 Saturn SL2 is located under the car, towards the backside, near the rear wheels. It is positioned on the driver's side, just forward of the fuel tank. Take note of the two bracket retaining bolts and the three fuel lines entering and exiting the filter.

Disconnect the Fuel Lines:

Before disconnecting the fuel lines, remove the two bolts holding the bracket in place. These bolts may be rusted, so proceed with caution. Once the bolts are removed, carefully disconnect the fuel lines. The connectors have a two-part system: squeeze the inner plastic clip and pull the line. Be cautious, as the filter is still full of fuel. Have your drip pan ready to catch any spilled fuel.

Dispose of the Old Fuel Filter:

Once the fuel lines are disconnected, carefully remove the old fuel filter from the bracket. It is important to handle the old filter with care and dispose of it properly. Place it in an approved container for disposal or recycling.

Clean the Area:

Before installing the new fuel filter, ensure that the area is clean and free of any debris or residue. Wipe down the surrounding components and the bracket to prevent any contamination from entering the fuel system.

By following these steps, you will have successfully disconnected the fuel filter on your 1999 Saturn SL2. Remember to refer to your vehicle's repair manual or seek guidance from a qualified mechanic if you have any doubts or concerns during the process.

Remove the tubes from the filter

To remove the tubes from the filter of a 1999 Saturn SL2, you will need to first relieve the fuel system pressure. You can do this by removing the fuel pump fuse, which is located inside the vehicle on the passenger side. Next, start the car and let it run until it stalls, this will drain the fuel from the system.

Now, locate the original fuel filter. It will be on the driver's side, just forward of the gas tank. You will need to remove the two bolts holding the bracket in place. These bolts may be rusted, so be careful not to break them. Once the bolts are removed, you can disconnect the fuel lines. These connectors are a two-part system, so you will need to squeeze the inner plastic clip and pull the line. Be careful, as the filter is still full of fuel. Have a drip pan ready to catch any spills.

At this point, you can remove the tubes from the filter by pushing on the tabs. Some gasoline may leak from the filter, so be prepared with a shop cloth and a container to capture any spilled fuel.

Insert the new filter

Now that you've located the fuel filter, removed the bolts, and disconnected the fuel lines, it's time to insert the new filter.

First, insert the new filter into the new bracket and attach the new clips. If you purchased an OEM filter, it should come with the bracket and clips. If you didn't buy an OEM filter, you may need to reuse the bracket from the old filter.

Next, slide the bracket and filter into place and attach the fuel lines. Be careful, as the filter is still full of fuel. Have your drip pan ready to catch any spills.

Once the new filter is in place, reinstall the bolts that hold the bracket and fuel lines in place.

Now, you can reinstall the fuel filter fuse.

Turn the ignition key to the "RUN" position and hold it for a few seconds. You should hear the fuel pump repressurize the fuel system and fill the new filter with fuel.

Finally, start the car. If it doesn't turn over immediately, you may need to slightly depress the gas pedal.

Check for leaks and take the car for a short test drive.

Congratulations! You've successfully changed your 1999 Saturn's fuel filter.
