how to cjange del sol fuel filter

Changing the fuel filter on a Honda Del Sol is a simple task that can be completed in around 15-20 minutes. Before starting, it is important to take safety precautions such as loosening the gas cap to release pressure in the fuel system and covering the positive post of the battery to avoid any accidents. To begin, use a 9/16 flare wrench to loosen and remove the fuel line on the right side of the filter, and place shop rags underneath to catch any leaking fuel. Next, use a 17mm wrench to loosen and remove the line on the left side of the filter, connecting it to the fuel rail. Remove the copper crush gaskets and loosen or remove the holder/bracket that keeps the filter in place. Finally, install the new filter by reversing the removal process, ensuring all connections are tightened and no leaks are present.

Prepare tools, materials and safety precautions

Prepare the necessary tools and materials before beginning the process of changing the fuel filter in your Honda Del Sol. This maintenance task typically takes around 15-20 minutes to complete.

  • Shop rags
  • Fuel filter with copper crush gaskets
  • 9/16 brake line flare wrench
  • 10mm socket
  • 3/8" extension ratchet
  • 17mm wrench or socket/ratchet
  • Line wrench
  • Thread tape rated for fuel applications

Additionally, ensure you take the necessary safety precautions. Before beginning, it is important to disconnect the negative battery and loosen your gas cap to release the pressure in the fuel system. Cover your positive battery post to prevent your wrench or ratchet from touching it while you work. You should also place shop rags underneath the filter to soak up any fuel that may leak out.

It is also suggested to remove the fuel pump fuse and turn on your car, causing the car to shut off and the fuel lines to depressurize.

Loosen the gas cap and disconnect the battery

Before you begin to change the fuel filter on your Honda Civic del Sol, there are a few important steps to take to ensure your safety and make the process easier. One key step is to loosen the gas cap and disconnect the battery.

Loosening the gas cap is crucial to releasing the pressure in the fuel system. By doing this, you reduce the risk of fuel spraying out when you start disconnecting the fuel lines. This is a simple but often overlooked step that can make a significant difference in the fuel filter replacement process.

Disconnecting the battery is another important safety precaution when working on any vehicle repairs involving electrical or fuel-related components. Disconnecting the battery prevents the risk of sparks, which could lead to a dangerous situation when combined with leaking fuel. It also ensures that your tools do not accidentally ground any electrical components.

Additionally, covering the positive post of your battery is essential to prevent your wrench or ratchet from making contact. This step helps avoid any potential electrical issues during the fuel filter replacement process.

While disconnecting the battery may result in losing your radio settings, it is a small price to pay for ensuring your safety and peace of mind. Taking these precautions when changing your fuel filter can help make the process smoother and reduce the chances of encountering any unexpected challenges.

Remove the fuel line

To remove the fuel line from a Honda Del Sol, you will need a 9/16 flare wrench, shop rags, and a 17mm wrench.

First, use your 9/16 flare wrench to loosen and remove the fuel line going into the right side of the filter. Place your shop rags underneath the filter to soak up any fuel that leaks out. Next, use your 17mm wrench to loosen and remove the line on the left side of the filter that connects it to the fuel rail. As you remove the bolt, remove any copper crush gaskets on either side of the line.

It is important to note that the fuel filter is bolted to the firewall, which is located to the right of your battery. Before beginning this process, you should loosen your gas cap to release the pressure in the fuel system. Additionally, it is important to cover the positive post of your battery so your wrench or ratchet don't touch it while you're working to avoid any sparks.

Another way to relieve pressure from the system is to remove the fuel pump fuse and turn your car on. It will shut off by itself.

Disconnect the holder/bracket

Disconnecting the holder/bracket is a crucial step in changing the fuel filter in your Del Sol. Here's a detailed guide on how to approach this step:

Locating the Holder/Bracket:

Begin by identifying the holder or bracket that secures the fuel filter in place. This bracket is attached to the firewall and holds the fuel filter firmly. It's typically located near the battery, on the right side.

Tools Required:

For this step, you'll need a 10mm socket or wrench and a 3" extension. A ratchet will also come in handy to reach the bolt. It's worth noting that accessing this bolt can be a bit challenging due to the confined space.

Loosening the Bolt:

Use the 10mm socket or wrench to loosen the bolt that secures the holder/bracket. You'll need to access this bolt from the opposite side, so it may require some maneuvering. Be cautious when working in tight spaces to avoid stripping the threads or damaging surrounding components.

Removing the Bracket:

Once the bolt is loosened, you can remove the bracket. Gently wiggle it free, being mindful of the fuel filter still attached to it. You may need to tilt or adjust the filter to get the bracket out smoothly. Place the old bracket aside, as you'll be reusing it when installing the new fuel filter.

Handling the Fuel Filter:

The fuel filter will now be free, but it's still attached to the old bracket. Carefully detach the filter from the bracket. You may need to jiggle it slightly, but be cautious to avoid spilling any remaining fuel. Place the old filter in a safe container, as it will still contain fuel.

By following these steps, you'll successfully disconnect the holder/bracket, allowing you to proceed with replacing the fuel filter in your Del Sol. Remember to work carefully and refer to repair manuals or seek professional guidance if you're unsure about any steps.

Install the new filter

To install the new fuel filter, first attach both lines to the filter. The copper crush gaskets go on both sides of the leftmost rubber line. Place one between the bolt and the line, and another between the line and the filter.

Next, reinstall the filter into the bracket, and reinstall the bracket onto the main bracket that's attached to the firewall. Ensure everything is tightened up.

Tighten your gas cap and start the motor. Check for any leaks. If you see no gas leaking from the lines, your job is finished. If you do see fuel leaking, either the lines are not tight enough, or you forgot to install the copper gaskets.

Some other tips include:

  • Cover your positive battery post so your wrench/ratchet don't touch it while you're working.
  • Disconnect the negative battery and remove the gas cap to let air out.
  • When removing the 17mm nut, put another wrench below it (probably a 19).
  • Use a line wrench, as the fitting is brass and rounds off easily.
  • Buy some thread tape rated for fuel applications so it does not leak.
