Replacing Fuel Filter In Saab 93: Step-By-Step Guide

Changing a fuel filter on a Saab 9-3 is a relatively simple task. The fuel filter is located underneath the vehicle, either in front of the left rear wheel or the right rear wheel, depending on the model. Before replacing it, open the fuel cap to release the internal pressure in the circuit, then disconnect the tubes by unhooking the respective clips. Remove the filter from its support, insert the replacement, and reconnect the tubes.

Depressurise the fuel system

Depressurising the fuel system is an important step when changing the fuel filter on a Saab 9-3. This is to ensure that fuel does not spray out when you undo the fuel lines from the filter.

Step 1: Remove the Fuel Cap

Remove the fuel cap to release the internal pressure in the circuit. This will ensure that most of the pressure in the fuel system is released.

Step 2: Remove the Fuel Pump Fuse

Start the car and remove the fuel pump fuse from the fuse box while the engine is running. For a Saab 9-5, this is the #15 20A fuse. Consult your car manual for the precise location of the fuse box and the correct fuse to remove.

Step 3: Wait for the Engine to Stall

Once the fuel pump fuse is removed, wait for the engine to stall and turn off. This will ensure that the engine burns up the remaining fuel in the fuel lines, leaving them depressurised.

Step 4: Turn Off the Ignition and Replace the Fuse

Once the engine has stalled and turned off, turn off the ignition and put the fuse back in its place.

By following these steps, you will safely depressurise the fuel system and can proceed with removing and replacing the fuel filter on your Saab 9-3. Remember to always take the necessary safety precautions when working with flammable liquids.

Remove the fuel filter splash guard

To remove the fuel filter splash guard on a Saab 9-5, follow these steps:

First, reduce the fuel pressure by removing the fuel pump fuse (number 15) while the engine is idling. Once the engine has stopped, turn off the ignition and replace the fuse.

The fuel filter splash guard is clipped onto the fuel filter and held in place with a tie wrap. Cut the tie wrap and remove the guard.

Now, loosen the front fuel line (this is on the upper right). Fuel will start to come out, so have a container ready to catch it. You will need to remove the front and rear fuel lines once most of the fuel has come out.

Take out the bolt for the filter clamp and remove the filter.

Drain the fuel from the filter

To drain the fuel from the filter of a Saab 9-3, you must first relieve the fuel system pressure. This can be done by removing the fuel pump fuse from the fuse box while the car is running. This will cause the engine to burn up the fuel from the fuel lines, leaving them depressurized. Once the car stalls, turn off the ignition and replace the fuse.

Now, locate the fuel filter. In the Saab 9-3, the fuel filter is located underneath the vehicle, in front of the right rear wheel, next to the fuel tank. Place a drip pan under the filter to catch any fuel that may leak out from the lines.

The next step is to remove the banjo bolts that connect the fuel lines to the filter. Before undoing the banjo bolts, grip the body of the filter with a 25mm wrench to avoid snapping the bracket. Once the banjo bolts are removed, you can then take out the bolt for the filter clamp and drop the filter.

It is important to note that working with fuel can be dangerous, so always take the necessary safety precautions. Ensure you are wearing protective eyewear and have a fire extinguisher nearby. Do not smoke or bring any open flames near the workspace.

Disconnect the fuel lines

Disconnecting the fuel lines on a Saab 9-3 is a relatively straightforward process, but it is important to take the necessary safety precautions when working with flammable liquids. Here is a detailed guide on how to disconnect the fuel lines on your Saab 9-3:

Before beginning, ensure that you have the necessary tools and safety equipment. You will need a socket and ratchet set with an extension, an open-ended spanner set, and a fire extinguisher. It is also recommended to wear protective eyewear and avoid smoking or open flames during this process.

Start by locating the fuel filter. On the Saab 9-3, the fuel filter is typically found underneath the vehicle, either in front of the left or right rear wheel, depending on the model year and engine type. Once you have located the fuel filter, follow these steps:

• Relieve the fuel system pressure. Start the car and remove the fuel pump fuse from the fuse box while the engine is running. This will cause the engine to burn up the fuel in the lines, depressurizing the system. Once the car stalls, turn off the ignition and replace the fuse.
• Remove any fuel filter splash guard or stone guard that is protecting the fuel filter. This is typically held in place with a tie wrap, which can be cut and removed.
• Place a drip pan or container under the fuel filter to catch any fuel that may leak out during the disconnection process.
• Loosen the banjo bolts that connect the fuel lines to the filter. These bolts can become rusted and difficult to remove, so it is recommended to soak them with penetrating oil for at least 24 hours before attempting to remove them. Always make sure to grip the body of the filter with a wrench to avoid snapping the bracket.
• Disconnect the fuel lines from the fuel filter. Some models may have quick-connect fuel lines that require a special tool for disconnection. Be careful as fuel may start to leak out during this process.
• Remove the bolt holding the fuel filter bracket in place and drop the filter.

By following these steps, you can safely and effectively disconnect the fuel lines on your Saab 9-3. Remember to work carefully and always prioritize your safety when working with flammable liquids.

Remove the filter

To remove the fuel filter on a Saab 9-3, you will need to first relieve the fuel system pressure. This can be done by removing the fuel pump fuse from the fuse box while the car is running, which will cause the engine to burn up the fuel from the fuel lines, leaving them depressurised. Once the car stalls, turn off the ignition and replace the fuse.

Next, locate the fuel filter. On some models, it is located in front of the right rear wheel, next to the tank. On other models, it is located in the engine compartment, behind the engine, and next to the bulkhead.

Now, remove the stone or splash guard that is protecting the fuel filter from debris. Place a drip pan underneath the filter, as some fuel will leak from the lines. Grip the body of the filter with a 25mm wrench and undo the banjo bolts that connect the fuel lines to the filter.

With the filter disconnected from the fuel system, remove the bolt that holds the bracket in place and drop the filter. Clean the banjo bolts of any rust using a wire brush and prepare new seals.
