Changing The Fuel Pump And Filter In A 1999 Honda Accord

If your 1999 Honda Accord is feeling sluggish on steep roads, you may need to change the fuel pump and filter. This is a job that can be done by a professional, but it will come at a price. If you want to save some money, you can do it yourself, but it will take some time and effort. This introduction will guide you through the process of changing the fuel pump and filter on your 1999 Honda Accord.

Disconnect the battery and relieve the fuel system pressure

Disconnecting the battery and relieving the fuel system pressure are the first steps in replacing the fuel filter on a Honda Accord. Here is a detailed, step-by-step guide on how to do this:

Disconnect the battery:

• Locate the negative (black) terminal on the battery.
• Disconnect the negative terminal. It is important to disconnect the negative terminal first to avoid any electrical short circuits.

Relieve the fuel system pressure:

• Remove the gas cap to relieve gas pressure from the fuel system. This is a crucial step to make the subsequent tasks safer and easier.
• Alternatively, you can loosen the gas pressure bolt at the end of the fuel rail to relieve the pressure. Remember to re-tighten it once you're done with the job.

By following these steps, you will be able to safely proceed with replacing the fuel filter on your Honda Accord. It is important to work in a well-ventilated area when performing these tasks, as gas fumes can be harmful.

Locate the fuel filter

To locate the fuel filter on a 1999 Honda Accord, follow these steps:

Firstly, it is important to note that the fuel filter location is different for certain model years of the Honda Accord. For the 1990-1994 models, the fuel filters are located on the passenger's side firewall. For the 1995-2002 models, including your 1999 Accord, the fuel filters are located on the rear of the engine, near the brake master cylinder.

Now that you know the fuel filter is located at the rear of the engine, you can proceed with locating it. Park your car in a well-ventilated area and disconnect the negative battery terminal. This is an important safety precaution as you will be working with fuel lines and gas fumes can be harmful.

Next, remove the gas cap to relieve any pressure from the fuel system. This step is important as it will make it easier to remove or unplug the necessary parts.

At this point, you should be able to see the fuel filter located on the rear of the engine, near the brake master cylinder.

In the next steps, you will be removing the fuel lines and clamp bolts to access and replace the fuel filter. Remember to place a fluid catch pan under the fuel lines to catch any spilled gas during this process.

Remove the lower fuel line and the upper fuel line Banjo bolt

To remove the lower fuel line and the upper fuel line Banjo bolt, you will need a 14mm wrench and a 17mm flare nut wrench.

First, use the 14mm wrench to loosen the nut from the lower fuel line by rotating it counterclockwise. Place a fluid catch pan under the fuel line to catch any spilled gas. Once the nut is removed, pull the lower fuel line off and set it aside.

Next, use the 17mm flare nut wrench to loosen the Banjo bolt on the upper fuel line. Again, rotate the wrench counterclockwise to loosen the bolt, and then remove the fuel line by hand.

Now that you have removed the lower and upper fuel lines, you can move on to removing the clamp bolts that hold the fuel filter in place.

It is important to perform this task in a well-ventilated area due to the harmful nature of gas fumes.

Remove the clamp bolts

To remove the clamp bolts from your Honda Accord, you will need a 10mm flare nut wrench. This is the tool required to unfasten the two bolts from the clamp that holds the fuel filter in place.

First, locate the fuel filter. In Honda Accords manufactured between 1990 and 1994, the fuel filter is located on the passenger's side firewall. In Accords produced from 1995 onwards, the fuel filter is located at the rear of the engine, near the brake master cylinder.

Once you have located the fuel filter, use the 10mm flare nut wrench to remove the two bolts from the clamp. These bolts hold the fuel filter in place. Be sure to place a fluid catch pan under the fuel filter to catch any spilled gas.

After removing the clamp bolts, you can proceed to unclip the alignment hole holding the top of the fuel filter in place. Then, carefully remove the fuel filter from the clamp. Dispose of the old filter properly and get ready to install the new fuel filter.

It is important to work in a well-ventilated area when performing this task, as gas fumes can be harmful.

Replace the fuel filter and reattach the clamp

To replace the fuel filter and reattach the clamp on a 1999 Honda Accord, follow these steps:

Firstly, unclip the alignment hole that holds the top of the fuel filter in place. Then, remove the fuel filter from the clamp. Dispose of the old filter and get ready to place the new one in the clamp.

Now, insert the new fuel filter into the clamp, ensuring it is securely in place. Then, reattach the clamp to its original location and secure it with the two 10 mm bolts.

At this point, you should reconnect the upper and lower fuel lines. Before reconnecting the upper fuel line, insert two new washers. Then, tighten the 17 mm Banjo bolt to a snug fit. Reconnect the lower fuel line and secure it with the 14 mm bolt.

Finally, double-check that your fuel lines and bolts are properly secured.

• One 14 mm bolt for the bottom fuel line
• One 17 mm Banjo bolt for the upper fuel line
• Two 10 mm bolts for the fuel filter bracket
