Removing the fuel tank from a 1992 Honda Civic is a complex process that requires careful attention to safety. It is important to ensure the fuel tank is empty before attempting to remove it. This can be done by driving the car until the tank is empty or siphoning the fuel with a kit. Once the tank is empty, the next steps involve disconnecting the battery, jacking up the car, and removing bolts, straps, and wires that hold the tank in place.

What You'll Learn

Empty the tank
Emptying the fuel tank of your 1992 Honda Civic is a crucial step before removing the tank itself. Here is a detailed guide on how to do it safely and effectively:
Firstly, it is important to note that the fuel pump alone may not completely empty the fuel tank. There could still be a significant amount of fuel remaining, so it is crucial to take the necessary steps to drain the tank as much as possible. If your car is still running, drive it until the tank is close to empty.
Next, you'll need to relieve the fuel system pressure. You can do this by removing the gas cap or consulting a professional for guidance on the fuel pressure relief procedure.
Now, disconnect the battery. This is an important safety precaution as you will be working with fuel lines and wires, and you want to avoid any potential sparks that could ignite fuel fumes.
Then, locate the 17mm bolt on the left rear corner of the tank. This bolt is likely covered in undercoating, so use a wire brush or a flat screwdriver to scrape away the coating. Place a pan underneath the bolt to catch the fuel, and then use a 17mm wrench to open the bolt and start draining the tank.
Once you've started draining, jack up the front right corner of the car. This will cause the remaining fuel to flow towards the corner of the tank with the drain plug, ensuring a more complete drainage.
Finally, while the tank is draining, carefully inspect the fuel pump and fuel lines for any signs of damage or leaks. Ensure that all fuel is drained or siphoned before proceeding with the removal of the fuel tank. Remember to dispose of the drained fuel responsibly and adhere to local regulations for fuel disposal.

Disconnect the battery
Disconnecting the battery is the second step in removing the fuel tank from a 1992 Honda Civic. The first step is to empty the tank as much as possible by driving the car until it runs out of fuel.
To disconnect the battery, safety precautions must be taken. Put on a set of insulated work gloves and goggles to protect yourself from sparks and corrosive chemicals. Work in a well-ventilated area and remove any metal accessories that could get in the way.
Once you have prepared your workspace, locate the negative terminal on the battery. It will be marked by a black cap or a minus sign. Using a wrench or pliers, loosen the negative terminal clamp and remove the cable.
After the negative cable is disconnected, move on to the positive terminal. Again, use your wrench or pliers to loosen the clamp and remove the cable.
With both cables disconnected, you can now remove the battery from the car. Be sure to secure any loose cables with zip ties to prevent them from accidentally reconnecting.
It is important to note that disconnecting the battery will cause the settings of certain electronic features to reset. This includes warning lights, the radio, and possibly the codes for driving aids such as traction control and power steering. To avoid this, you can purchase a "memory saver" device and a battery booster pack or auxiliary power source to retain your vehicle's settings while the battery is disconnected.

Jack up the car
Jacking up your car is an essential step in removing the fuel tank of a 1992 Honda Civic. This process will require a floor jack and jack stands. Before you start, ensure that your car is parked on a flat, level surface.
First, you need to get the fuel tank as empty as possible. If your car is still running, drive it until the tank is almost empty. Next, disconnect the battery. This is an important safety precaution as you will be working with a fuel pump and wires, and you don't want any sparks to ignite the fuel fumes.
Now you can start jacking up the car. Place the jack at the rear of the car and jack it up as high as possible. You want to get it snug against the gas tank, but be careful not to jack up the car further than necessary. Once the car is securely raised, place the jack stands underneath to support the weight.
At this point, you can start to unbolt the tank. As you do this, the jack will prevent the tank from falling. Remember to slowly lower the jack as the tank becomes unsecured, and always double-check for any missed bolts, wires, or lines.
It is important to note that you should only attempt this procedure if you have the necessary tools, experience, and knowledge. Working underneath a raised vehicle can be dangerous, so ensure you have a clear understanding of the process and the potential risks involved.

Remove bolts/straps
Before removing the bolts and straps that hold the fuel tank in place, there are a few important steps to follow. Firstly, it is recommended to get the tank as empty as possible. If the car is still running, drive it until the tank is empty. Disconnect the battery to avoid any chance of sparks igniting the fuel fumes. Jack up the rear of the car as high as possible and place it on jack stands. Now, you can start to remove the bolts and straps.
The fuel tank is held in place by straps, which are typically flexible metal braces. These can be carefully removed and reused if needed. The straps are bolted underneath the car and go over the tank. To remove them, you will need a 12 mm socket with a 3/8 ratchet. In some cases, you may need to use a slightly larger socket, such as a 13 mm, due to grime on the nut. Make sure to remove all the bolts securing the straps in place.
In addition to the straps, there may be other bolts or fasteners holding the fuel tank in place. For example, there is a bolt on the left rear corner of the tank that will need to be removed with a 17 mm wrench. This bolt is likely covered in undercoating, so you may need to scrape it off with a wire brush or flat screwdriver before removing the bolt.
Once all the bolts and straps have been removed, slowly lower the jack while double-checking for any missed bolts, wires, or lines. It is important to be cautious and thorough during this process to ensure that everything is properly disconnected before completely lowering the fuel tank.

Disconnect wires/hoses
Disconnecting the wires and hoses is a crucial step in removing the fuel tank of a 1992 Honda Civic. Here is a detailed, step-by-step guide to help you through the process:
Disconnecting the Battery
Before you begin, it is essential to disconnect the battery. Working with a fuel pump and wires can be hazardous, and you don't want to risk any sparks igniting fuel fumes.
Fuel Pump and Sender Access
To access the fuel pump and sender, start by pulling up the back seat. There is usually a clip in the centre that allows the seat to swing forward. With the back seat removed, you will see a cover secured by four Phillips-head screws. Remove these screws to gain access to the fuel pump and sender.
Removing Electrical Wires
The electrical wires connected to the fuel pump and sender have clips that you need to remove. Carefully detach these clips to free the wires.
Disconnecting Hoses
Now, you will need to disconnect several hoses. First, locate the return line and remove the clamp. Then, focus on the left rear of the tank, where you will find a 17 mm bolt. This bolt is typically covered in undercoating, so use a wire brush or a flat screwdriver to scrape it off before removing the bolt. Additionally, there is a small hose at the left front of the tank (vent check valve) that needs to be removed. These hoses, on both the left front and rear of the tank, are hidden behind a plastic cover secured by three Phillips-head screws. When removing the screws, you will also pull out the push-plug.
Fuel Filler Hose and Fuel Tank Vapor Hose
Disconnect the fuel filler hose and the fuel tank vapor hose quick-disconnect fittings. These hoses are typically located at the front of the fuel tank.
Fuel Line Quick-Connect Fittings
Disconnect the fuel line quick-connect fittings, which are also positioned at the front of the tank.
By following these steps, you will have successfully disconnected the wires and hoses associated with the fuel tank of your 1992 Honda Civic. Remember to work carefully and consult a professional mechanic if you have any doubts or concerns.
