What You'll Learn
Using a hose and a fuel siphon system
First, ensure that you are working in a well-ventilated area, free from any open flames or sources of ignition. Put on protective gear, such as gloves, safety goggles, and a face mask, to avoid any fuel splashes or exposure to fumes. Locate the fuel tank, which is usually at the rear of the vehicle but may be under the hood, and refer to the vehicle's owner's manual if needed.
Next, purchase a fuel siphon system from an auto store. These are manually operated pumps designed to draw gasoline out of a car and into a container. Ensure that the system is approved for combustible materials to prevent any sparks near the gas tank, which could be hazardous. You will need around six feet of a small (3/8 inch) hose, as well as a pump to draw out the fuel.
Now, stick the hose of the fuel siphon system into the gas tank, ensuring it reaches the bottom. Then, use the pump to create suction and draw out the fuel. As you pump, be ready with your receptacle to collect the gasoline. Hold onto the end of the hose as it may start to move when the gas begins to flow.
If you do not have a pump but have a spare tube, you can use it to blow air into the tank, forcing the gas out of the other tube. Once you have drained the tank, remove the tube and refill the tank with fresh fuel. Properly dispose of the drained fuel by taking it to a hazardous waste disposal site or a recycling center. Do not pour it down the drain or into the soil, as it can contaminate the environment.
Additionally, if your vehicle has an electric fuel pump, you can use it to drain the fuel tank. First, locate the fuel pump fuse or relay in the vehicle's fuse box and remove it. Then, turn on the ignition without starting the engine; the fuel pump will activate and start draining the tank. Once empty, turn off the ignition and replace the fuel pump fuse or relay.

Locating the drain plug
Not all vehicles will have this drain plug, and you may instead see fuel lines, which are small, removable hoses underneath the tank. If you are unable to locate the drain plug, you can use these fuel lines to drain the tank. However, you must turn the car on and off repeatedly to force the gas out of the tank, as it uses the electric fuel pump to complete the process.
If you are having trouble locating the drain plug, refer to your vehicle's owner's manual for the precise location of the fuel tank and its components. Additionally, consider the make and model of your car, as some vehicles, such as Jeeps, Fords, and Alfas, may have drain bolts or other accessible bolts that can be used for drainage.
Once you have located the drain plug, the next step is to place a wide-mouthed container, such as a basin or a pan, underneath the plug to catch the fuel as it drains. This will ensure that the fuel is collected safely and can be properly disposed of at a hazardous waste disposal site or a recycling centre.

Using gravity to drain the tank
Using gravity to drain a fuel tank is a straightforward process, but it can be dangerous if not done correctly. Before you begin, ensure you are wearing protective gear, including gloves, safety goggles, and a face mask. It is also crucial to work in a well-ventilated area, free from any open flames or sources of ignition.
First, you will need to locate the fuel pump cover and remove it. Next, clamp the hose that runs from the fuel tank to the fuel pump with a pair of needle-nose vice grips. Once clamped, remove the hose from the fuel pump. Place the loose end of the hose into a pan or small jerry can to collect the fuel. Use the vice grips to control the flow of fuel, allowing you to shut off the flow when one container is full and replace it with another.
If you have access to a car lift or jack stands, you can use them to position your vehicle and take advantage of gravity to aid in the drainage process. This method can be particularly useful if you are looking to drain as much fuel as possible from the tank.
Additionally, you can run a vent hose from inside the tank (down to the bottom if possible) and out to a container placed on the driveway. Be sure not to push the hose too far into the tank. This method utilizes gravity to drain the fuel effectively.
It is important to note that this process may vary depending on the make and model of your vehicle, as fuel tank locations can differ. Always refer to your vehicle's owner's manual for specific instructions and safety precautions.

Using a manual pump
First, locate the fuel pump relay in your vehicle's fuse box and remove it. Then, turn on the ignition without starting the engine. This will activate the fuel pump, and it will start draining the tank. Once the tank is empty, turn off the ignition and replace the fuel pump fuse or relay.
If you are using a jack stand, position your vehicle on the stand, locate the fuel tank drain plug, and remove it. The fuel will flow out of the tank and into a container below.
Another method is to remove the line from the fuel filter that is coming from the fuel tank, not the side going to the engine bay. Be careful as the fuel system may be under pressure. Use a 3/8 hose and slide it over the metal part of the line you removed from the filter. Put the other end of the hose into your gas can. Look for a red or grey wire at the top of the driver's side of the firewall. It will have a black plastic connector and a spade connector inside. Use a piece of wire to connect this wire to 12 V +. This will run the fuel pump and pump the gas through the hose and into your gas can.
If you are unable to use the fuel pump to pump the gas out, get a reel-style pump or a 12-volt electric fluid pump suitable for pumping gas. Insert a hose straight down the filler neck and connect the pump to 12 volts if using an electric pump. Pump the fuel out.

Safety precautions
Safety should be a top priority when draining a fuel tank with a hose. Here are some detailed safety precautions to follow:
- Use Personal Protective Equipment (PPE): Before starting, put on safety goggles to protect your eyes from any splashes or fumes, and wear gloves to avoid direct contact with the fuel. It is also recommended to wear old clothes that cover your arms and legs, and closed-toe shoes. This will reduce the risk of skin exposure to the fuel and potential burns.
- Work in a Well-Ventilated Area: Ensure that the area where you are working is well-ventilated. Open doors and windows, or perform the task outdoors if possible. Fumes from the fuel can be toxic, so it is important to avoid inhaling them. Consider using a respirator or a face mask rated for organic vapors to further protect yourself from inhaling toxic fumes.
- No Ignition Sources: Any sources of ignition, such as flames, sparks, or hot surfaces, should be eliminated from the work area. This includes turning off any nearby engines or machinery that may produce sparks. Do not smoke or have any open flames nearby. Remember that fuel vapors can travel, so ensure there are no potential ignition sources in the vicinity.
- Containment and Absorbent Materials: Have absorbent materials, such as sand or cat litter, and containment booms or pads readily available in case of spills. This will help you quickly contain and absorb any spilled fuel, reducing the risk of fires, explosions, or environmental contamination.
- Use a Proper Container: Always use an approved fuel container to collect the drained fuel. Never use containers that have held other substances, as this could be dangerous. Ensure the container is properly labeled and grounded to prevent static electricity buildup, which could cause sparks or an explosion.
- Safe Hose Handling: When inserting the hose into the fuel tank, do not suck on the hose to start the flow of fuel. This can cause fuel to enter your mouth, which is dangerous and unpleasant. Instead, blow into the hose to check for proper placement, and then use a manual or electric pump to transfer the fuel to the container.
- Avoid Skin Contact: Fuel can be harmful to your skin, so avoid direct skin contact. If you accidentally come into contact with fuel, immediately wash the affected area with soap and water. Seek medical attention if irritation or other symptoms persist.
- Post-Task Clean-up: Once you have finished draining the fuel tank, properly disconnect the hose, turn off any pumps, and store all tools in a safe place. Clean up the work area, ensuring that all spilled fuel is absorbed and disposed of correctly. Wash your hands and any exposed skin thoroughly after completing the task.
Remember, working with fuel can be hazardous, so it is important to take your time, follow instructions, and prioritize safety at all times. If you are uncomfortable or unsure about any aspect of the task, seek professional assistance.
