Replacing The Fuel Pump In A 1999 Honda Accord

Replacing the fuel pump on a 1999 Honda Accord is a complex task. The fuel pump is located inside the gas tank, and to access it, you'll need to siphon the gas, raise and secure the car, disconnect the fuel-sending unit and fuel lines, remove the tank straps, and then finally, you can remove and replace the fuel pump.

Siphoning out the gas tank

To siphon out the gas tank of a 1999 Honda Accord, you will need a tube and a safe container to pour the gasoline into. Insert the tube into the tank through the gas cap. Create a vacuum by blowing into the tank through the tube and pour the gasoline into the safe container. Drain out as much gas as possible. If you have access to one, use a vacuum pump to avoid accidentally sipping up gasoline.

Raising and securing the car

To raise and secure your 1999 Honda Accord, you will need a jack and jack stands. Place the jack under one of the car's safety points and raise the car. Once the car is raised, position the jack stands under the car to secure it in the air. This step is crucial to ensure your safety and provide you with the necessary access to the fuel pump.

When working with a car jack, it is important to follow safety protocols. Ensure that the car is parked on a flat, level surface and engage the parking brake to prevent accidental movement. Additionally, chocking the wheels can provide added security. Before placing any part of your body under the vehicle, verify that the car is securely supported by attempting to gently shake the vehicle. If the car moves or feels unstable, adjust the jack and jack stands as necessary.

Once you have confirmed that the car is securely raised and supported, you can proceed with the next steps of accessing and replacing the fuel pump. Remember to exercise caution and follow the subsequent instructions carefully.

Now, you can proceed to disconnect the fuel-sending unit, which is located underneath the access hatch inside the trunk. Open the hatch and carefully disconnect the unit. At this stage, you will also need to remove the rear left wheel to access and disconnect the four fuel lines located behind it.

Disconnecting the fuel-sending unit

To disconnect the fuel-sending unit of a 1999 Honda Accord, follow these steps:

Firstly, locate the access hatch inside the trunk. This is where the fuel-sending unit is found. Open the hatch and look for the unit.

Once you have located the fuel-sending unit, you will see that it is held in place by screws. Remove these screws carefully. There may also be a white retainer at the 7 o'clock position that is stopping you from fully removing the unit.

If you are unsure about any of the connections, it is best to consult a mechanic or a professional.

After the screws have been removed, and any retainers released, carefully disconnect the unit. Ensure that you do not damage any of the surrounding components or connections.

Now that the fuel-sending unit has been successfully disconnected, you can begin to remove the fuel lines. There are four fuel lines in total, located behind the left rear wheel.

This process should be carried out with caution, as it involves flammable liquids and gases. Ensure the area is well-ventilated and that no sources of ignition are present.

Disconnecting the fuel lines

Before beginning, ensure that you have raised and securely supported your car using a jack and jack stands. This will provide you with safe access to the undercarriage and the necessary clearance to work on the fuel system.

Now, let's turn our attention to the fuel lines. There are four fuel lines that need to be disconnected, and they are all located behind the left rear wheel. To access them, you will first need to remove the left rear wheel. Once the wheel is removed, you will be able to see the fuel lines clearly.

The four fuel lines consist of two hard lines, a high-pressure line, and a brass line that connects directly to the fuel tank. Begin by carefully disconnecting the two hard lines, using the appropriate tools and safety precautions. It is important to note that fuel lines carry highly flammable fuel, so ensure that there are no sources of ignition nearby, and be cautious not to damage the lines during this process.

After disconnecting the hard lines, turn your attention to the high-pressure line. This line is under significant pressure, so exercise extreme caution when detaching it. You may need specialized tools to safely release the pressure and disconnect the line.

Finally, disconnect the brass line that connects directly to the tank. This line is typically secured with a fitting or clamp, which you can loosen and remove. Again, be cautious not to damage the line, and ensure that any residual fuel is contained and disposed of properly.

By following these steps, you will have successfully disconnected the fuel lines, allowing you to access and replace the fuel pump on your 1999 Honda Accord. Remember to work safely and methodically, and always refer to a qualified mechanic if you have any doubts or concerns.

Removing the tank straps

To remove the tank straps, you will need to place a hydraulic jack with a long piece of wood under the tank. The tank straps are held in place with 14mm bolts, so you will need to loosen these with a suitable tool before removing the straps.

Once the straps have been removed, slowly lower the tank to relieve the pressure from the jack. You may need to remove the exhaust heat shield to access one of the 14mm strap bolts. This will depend on the specifics of your Honda Accord.

It is important to take your time and be careful during this process, as the fuel tank is a crucial and potentially dangerous component of your vehicle. Ensure that you have a suitable workspace and that your car is securely raised and supported before beginning any work.

If you are unsure about any part of this process, it is always best to consult a qualified mechanic or seek specialist advice.
