To drain the fuel tank of a Fiero, you will need to drop the tank and remove the fuel level sensor and fuel pump assembly. This can be a challenging process due to the 90-degree bend at the tank, which makes it difficult to siphon fuel through the fill tube. However, an alternative method is to carefully remove the big hose at the tank and siphon or pump at that point. Another option is to use an AC hose with a valve release pin, but it is important to ensure that the pin is the correct length and not worn, as this may affect its functionality.

What You'll Learn
Drop the tank and remove the fuel level sensor
To drain your Fiero fuel tank, you will need to drop the tank and remove the fuel level sensor. Here is a step-by-step guide to help you through the process:
First, locate the fuel tank and place a drain pan or container underneath it to catch any fuel that may spill during the process. You will then need to disconnect the fuel lines and any electrical connections attached to the tank. Be sure to have rags or absorbent pads on hand to wipe up any spilled fuel and to catch any drips.
Once the connections have been disconnected, carefully lower the tank and secure it in a stable position. Now, locate the fuel level sensor, which is usually attached to the top or side of the tank. There may be a protective cover or shield that you will need to remove to access the sensor. Be careful not to damage any other components or connections during this process.
With the sensor exposed, you can now begin to remove it. The sensor is typically held in place with screws or bolts, so have the appropriate tools on hand to remove them. Once the screws have been removed, carefully pull the sensor out, noting any clips or connectors that may need to be detached as you go.
At this point, the fuel level sensor should be successfully removed from the tank. Be sure to dispose of or recycle the sensor properly, as it may contain hazardous materials. With the sensor removed, you will now be able to drain the fuel tank.

Remove the fuel pump assembly
To remove the fuel pump assembly, you will first need to drop the tank. This will give you access to the fuel pump, which is located inside the tank. Once you have dropped the tank, you can begin to remove the fuel pump assembly.
First, locate the fuel lines that connect to the fuel pump. These will need to be carefully detached. You will also need to disconnect any electrical connections that are supplying power to the fuel pump. Be sure to label or mark these connections so that you can properly reinstall them if needed.
Next, you will need to remove the fuel pump module. This may involve unscrewing or unbolting any mounting hardware that holds the module in place. Be careful not to damage any components or the fuel tank itself during this process. Once the module is removed, you will have access to the fuel pump itself.
Finally, carefully remove the fuel pump from its housing. Take note of any O-rings or seals that may need to be replaced during reassembly. It is also important to handle the fuel pump carefully, as it may contain residual fuel or be subject to damage if dropped.
Once the fuel pump assembly has been removed, you can proceed with draining the fuel tank or performing any other necessary maintenance. Remember to exercise extreme caution when working with fuel systems, and ensure that the area is well-ventilated to prevent the buildup of flammable vapors.

Use an AC hose with a valve release pin
One method to drain a Fiero fuel tank is to use an AC hose with a valve release pin. This method works with most fuel systems. However, there are a few potential issues to be aware of. Firstly, most AC hoses only have the valve release pin on one end, so you need to ensure that you are using the correct end when attaching it to the valve. Secondly, some pins may be adjusted short or worn, which can cause issues with properly pushing the fuel valve in. Many pins have threaded bodies, allowing for adjustments to be made to the pin inside the hose end.
To use the AC hose with the valve release pin to drain the fuel tank, follow these steps:
- Locate the AC hose with the valve release pin at one end.
- Ensure that you are using the correct end of the hose by identifying the end with the valve release pin.
- Attach the AC hose to the fuel valve, making sure that the valve release pin is properly engaged.
- Adjust the pin inside the hose end if necessary to ensure a proper fit.
- Once the AC hose is securely attached, you can begin the fuel drainage process.
- Carefully open the fuel valve and allow the fuel to drain from the tank into an appropriate container.
- Monitor the drainage process to ensure that it is proceeding safely and without any leaks or spills.
- Close the fuel valve once the tank is drained or when you need to change containers.
By following these steps and paying close attention to the condition and attachment of the AC hose with the valve release pin, you can effectively and safely drain your Fiero fuel tank using this method. Remember to always take the necessary safety precautions when working with fuel and ensure proper ventilation in the work area.

Remove the big hose at the tank
To remove the big hose at the tank, you will need to locate the hose clamp that secures the hose to the tank. This is usually a metal or plastic ring that is tightened around the hose to hold it in place. Using a screwdriver or a hose clamp plier, loosen the hose clamp by turning it counterclockwise. Be careful not to break the clamp as they can be fragile. Once the clamp is loose, you can gently pull on the hose to remove it from the tank. There may be some residual fuel or vapors inside, so be prepared for this and have some rags or paper towels ready to catch any spills.
If the hose is difficult to remove, it may be due to a build-up of dirt, corrosion, or fuel residue. In this case, you can try working the hose back and forth to loosen it before pulling it off. Be careful not to use excessive force, as this may damage the hose or the tank. If necessary, you can apply a small amount of penetrating oil or lubricant to the connection between the hose and the tank to help loosen it.
Once the hose is removed, you can attach a siphon or pump to drain the fuel tank. This is a much easier method than trying to siphon through the fill tube due to the 90-degree bend at the tank. Ensure that you are in a well-ventilated area and take the proper safety precautions when handling fuel.
After draining the fuel tank, you can reinstall the hose. Ensure that the hose is correctly seated and secured with the hose clamp. Tighten the clamp by turning it clockwise with a screwdriver or hose clamp plier. Again, be careful not to over-tighten and damage the clamp.

Siphon or pump at the tank
To drain a Fiero fuel tank using the siphoning method, you can carefully remove the big hose at the tank and siphon at that point. This is because the 90-degree bend at the tank makes it difficult to siphon using the fill tube.
- Carefully remove the big hose at the tank: This step allows you to access the fuel tank for siphoning or pumping. It is important to be cautious during this step to avoid any damage to the hose or the tank.
- Set up your siphoning equipment: Obtain a siphon pump or a siphon hose to remove the fuel from the tank. Ensure that your siphoning equipment is suitable for use with gasoline and that you have a container ready to collect the drained fuel.
- Start the siphoning process: Place the siphon hose into the tank and begin siphoning by creating a suction effect. Ensure that the other end of the hose is securely placed in your fuel collection container.
- Monitor the process: Keep an eye on the siphoning process to ensure it proceeds safely and effectively. Depending on the method you choose, this step may take a few minutes to half an hour.
- Optional: Use a pump for faster draining: If you prefer a faster draining method, you can disconnect the fuel supply line from the tank and use a pump. Turn the key on, and the pump will empty the tank in approximately 30 minutes.
Remember to exercise caution when handling gasoline and ensure proper ventilation during the process. Always refer to your vehicle's manual or seek professional advice if you have any doubts or concerns.
