Siphoning: use a hose to transfer fuel from the tank to a container manually
Siphoning fuel from a car can be a risky and potentially dangerous task, but it is sometimes necessary. Knowing how to properly siphon gas can save you time and money. It is important to note that siphoning gas is illegal in some states and can also damage your vehicle if not done correctly.
To siphon fuel manually, you will need a hose, a container to hold the fuel, and a good seal around the fuel filler neck. The hose should be long enough to reach from the gas tank to the container on the ground. Insert one end of the hose into the tank, creating a seal around the filler neck, and use your mouth or a pump to create suction. The fuel will then flow through the hose and into the container. Ensure that you use a closed gas canister to prevent spills and inhaling of fumes.
If you are using your mouth to create suction, it is crucial to use clear tubing so you can see the gas moving through the tube and remove the hose before the gas reaches your mouth. Take care not to breathe in through the tube and inhale any fumes.
You can also use a mechanical air pump to force air through the short tube, increasing the pressure above the gas in the tank. This will cause the gas to flow through the longer tube into the gas can. Once the gas is flowing freely, you don't need to continue blowing or pumping as gravity will do the rest.
If you are uncomfortable siphoning fuel from your car or don't have the necessary equipment, you can always use a professional fuel drain service. These services use specialist equipment to safely and efficiently remove contaminated fuel from your car.

Drain plug: locate the drainage plug, place a pan underneath, and unscrew the plug
To get fuel out of a car using a drain plug, you'll first need to locate the drainage plug. The fuel tank is usually a large, solid metal container on the same side of your car as the gas filler neck. Use your gas door as a gauge—it is usually underneath the passenger-side seat.
Once you've located the drain plug, place a pan or receptacle directly underneath it to collect the fuel. Make sure you have enough drain pans to catch the amount of fuel you need to drain. The fuel will start to drain out as soon as the drain plug is fully removed, so be prepared for it to come out at full force.
You'll usually need a spanner or socket wrench to remove the drain plug. Loosen it with a wrench, then remove it completely by hand. Allow the fuel to drain until the tank is empty. This will take a long time—up to several minutes per gallon—so you should keep an eye on it.
Once the tank is empty, replace the drain plug tightly and properly dispose of or store the drained fuel. Move forward with any repairs or services that need to be done.

Manual pumps: insert a pump into the fuel tank, create suction, and let the fuel flow into the pump
If you have put the wrong fuel in your car, one way to drain it is to use a manual pump. This method is relatively inexpensive, easy to execute, and can be done without the help of a professional.
To start, you will need to purchase a manual pump. These are readily available at most auto shops and can be stored in your car for emergencies. Once you have the pump, simply insert it into the fuel tank. It is important to note that you should not use your mouth to create suction, as this can be dangerous. Instead, use the manual pump to create suction, which will cause the fuel to flow into the pump.
If your car has an electric fuel pump, it is likely installed inside the fuel tank. Electric fuel pumps are more common in modern, fuel-injected vehicles and are known for their ability to generate high pressure. They are usually mounted outside, as they are integrated into the line.
If you are uncomfortable draining the fuel yourself or do not have the necessary equipment, you can always use a professional fuel drain service. These services are widely available and can safely and efficiently remove contaminated fuel from your car. They can also flush out your fuel system to ensure that all traces of the wrong fuel are removed. While this option may be more expensive, it is often the safest and most effective way to get your car back on the road.

Fuel lines: turn the car on and off repeatedly to force the gas out of the tank
If you want to get fuel out of your car's fuel lines, one method is to turn the car on and off repeatedly to force the gas out of the tank. This method can be useful if you have filled your car with a small amount of the wrong type of fuel.
First, locate the fuel line and disconnect it from the engine. You may need to remove the fuel lines from the top and lower sections of the engine, especially if they are rusty. If the fuel filter nut is rounded off, you may need to install the fuel line nut in a vice to remove what is left of the fuel filter. Be sure to turn the fastener the correct way—righty-tighty, lefty-loosey.
Once the fuel line is disconnected, place the end in a container to catch the fuel. Then, turn the ignition on and off repeatedly. Each time you turn the ignition on, the fuel pump will pump fuel for several seconds. By cycling the ignition on and off, you can force the gas out of the tank and into your container.
This method can be messy, and you may want to have a pan or bucket underneath to catch any spills. It is also important to exercise caution when working with fuel, as it is flammable and can be dangerous if ingested by the engine. If you are uncomfortable with this process, consider using a professional fuel drain service, which can safely and efficiently remove contaminated fuel from your car.

Frequently asked questions
There are several ways to drain fuel from a car. One way is to use the siphoning method, which involves using a hose to transfer the fuel from the tank to a container manually. You will need a hose, a container to hold the fuel, and a good seal around the fuel filler neck. Insert the hose into the tank, create a seal around the filler neck, and use your mouth or a pump to create suction.
Another method is to use two hoses – one to transfer fuel out of the tank and another to transfer clean fuel back in. You will need two lengths of hose, a container for the contaminated fuel, and a container for the clean fuel.
This method is beneficial if you have filled your car with a small amount of the wrong fuel type. It ensures that you do not have to flush out the fuel tank and fuel system with the correct fuel.
Manual pumps are another effective way to drain fuel from a vehicle. They work by creating suction and are easier and less messy than siphoning. Simply insert the pump into the fuel tank, create suction, and the fuel will flow into the pump.
You should safely dispose of the contaminated fuel by contacting your local environmental waste disposal centre. Do not pour the fuel down a drain or sewer.
