The fuel tank in an automobile is designed to safely store the vehicle's fuel supply, typically located before or after the rear axle. Fuel tanks are not designed to allow fuel to leave the tank once it has entered, as this could cause serious malfunctions or fires. However, there may be instances when you need to drain your fuel tank, such as when you need to replace the fuel pump or fuel gauge sending unit, or if you've filled your tank with the wrong type of fuel. In such cases, it's important to take precautions and use the right equipment, such as a fuel siphon system or a manual/electric pump, to safely drain the fuel and avoid spills or health hazards. Additionally, proper disposal or storage of the drained fuel is crucial.

What You'll Learn
Draining your auto fuel tank
First, ensure that you are working in a well-ventilated area and that there are no open flames or sources of ignition nearby. Wear protective gear such as gloves, safety goggles, and a face mask to avoid any fuel splashes or inhaling toxic fumes.
One common method is to use a fuel siphon system. These are manually operated pumps that draw the gas out of your car and into a container. You can purchase a fuel siphon system at most auto stores. Make sure the one you buy is approved for combustible materials, as any sparks near your gas tank can be dangerous. You will need about six feet of a small hose, as well as a pump to draw the fuel out. Insert the hose into the fuel tank, ensuring it reaches the bottom, and then use the pump to draw out the fuel.
Alternatively, if your vehicle has an electric fuel pump, you can use it to drain the fuel tank. Locate the fuel pump fuse or relay in the fuse box and remove it. Then, turn on the ignition without starting the engine. The fuel pump will activate and start draining the fuel. Once the tank is empty, remember to turn off the ignition and replace the fuel pump fuse or relay.
Another method is to use a hose and a container. Insert the hose into the tank and use your mouth to suck on the other end, creating a flow of fuel. Then, transfer the fuel to the container. However, this method carries a risk of inhaling toxic fumes or accidentally ingesting fuel, which can be dangerous.
If your vehicle is equipped with a fuel tank drain plug, you can use a wrench to loosen it, and the fuel will start to drain out. Place a large pan or basin underneath to catch the fuel. Make sure to keep an eye on the fuel as it drains to prevent spills.
Finally, if you are uncomfortable performing this task yourself, you can always contact a professional service, such as Fuel Fixer, to drain your fuel tank for you. They offer 24/7 wrong fuel drain services to prevent any lasting damage to your engine.

Using a fuel siphon system
Fuel siphon systems are used to drain the gas tank of a car. They are particularly useful in emergencies, such as when you have put the wrong fuel in your tank, or when you need to transfer fuel from one container to another. Siphoning works by creating a vacuum that initiates the flow of fuel from a higher point to a lower point.
You can use a manual or automatic siphon pump. A manual pump will require you to pump it several times to suck the fuel out, while an automatic pump will only require the press of a button. Before you begin, make sure you are using a siphon pump that is approved for combustible materials, as any sparks near your gas tank could be dangerous. You will also need six feet or so of a small ⅜ inch hose.
The process of siphoning can be tricky, especially with newer cars that have small fuel-filler openings and spring-loaded flaps to stop fuel vapors from escaping. Newer vehicles also have a blocking mechanism at the bottom end of the filler neck to prevent pushing a siphon hose into the gas tank. If you are unsure how to insert the hose, consult the pump's manual. Make sure the end of the hose is pointing down, and that the fuel is flowing into a container.
It is important to note that draining a full tank of gas will take a long time. Additionally, the tank is not designed to allow gas to leave once it has entered, as this could cause serious malfunctions or fires. Therefore, it is recommended to consult with a trusted mechanic or read a manual before attempting to siphon gas.

Replacing your auto fuel tank
Firstly, you need to drain the gas out of your old tank. Some fuel tanks have a drain cock that will allow you to drain all of the gas neatly. If your tank does not have a drain cock, you will have to drain it by removing one of the fuel lines. Place a large pan under the drainage plug, then remove the plug with spanners or a socket wrench and let the fuel drain into the pan. Make sure to keep an eye on the fuel as it drains to ensure that it doesn't spill. You can also use a fuel siphon system, which is a manually operated pump that will draw the gas out of your car and into a container.
Next, disconnect the fuel lines. Gas tanks have more than one line, including a fuel supply line, a large fill tube, and a vent line. It is a good idea to take pictures of the setup before you take it apart. Then, you may need to drop the rear suspension. If an axle is blocking access to the old tank, disconnect the shocks and rest the rear suspension beam at the centre with a floor jack. Make sure you disconnect the brake lines too to avoid damaging them.
Finally, remove the two metal straps that are held in place by two metal bolts. Put the new tank into place, which can then be attached by the same straps. Go through the removal steps in reverse to ensure that the lines are in place, before filling the car up with the appropriate fuel. When you have replaced the tank, fill the car up and inspect the tank to check there are no drips or leaks from around the pipes and lines.

Safety precautions when handling fuel
Safety should always be a top priority when handling fuel. Here are some detailed safety precautions to follow when dealing with fuel:
Safe Fuel Storage
When storing fuel, always use approved containers and portable fuel tanks. Store fuel away from exits and passages, and away from heat sources, in a well-ventilated area. Only store the minimum amount of fuel needed and keep it at room temperature. Ensure that the containers are sealed tightly and elevated from the ground to prevent spills and leaks.
Handling Fuel
Never smoke or allow any open flames or sources of ignition near the fuel or its vapours, as these can easily ignite. Always keep a fire extinguisher nearby and ensure you have spill kits readily available in case of a spill. When transferring fuel, limit the hose length to 50 feet and always maintain contact with the fuel tank to prevent static electricity buildup.
Personal Protective Equipment (PPE)
Always wear the appropriate PPE when handling fuel, including eye protection, hearing protection, hand and foot protection, and flame-resistant clothing (FRC).
Safe Refueling
When refueling a vehicle, ensure the engine is turned off and that all passengers have disembarked. Check for any kinks in the fuel hose and ensure the nozzle is firmly inserted into the fill pipe. Avoid overfilling the tank and always reinstall the cap when refueling is complete.
Regular Maintenance
Regularly inspect and maintain your fuel storage tanks and equipment to ensure they are in good working condition and to prevent leaks. Keep the tanks clean and well-maintained, and follow all relevant safety regulations and guidelines.
