What You'll Learn
Using a siphon hand pump
First, you'll need to get a siphon hand pump. These pumps are inexpensive and can be purchased online or at most auto parts stores. Make sure to get a pump specifically designed for siphoning gasoline, as they have special features like fuel-resistant hoses and a vacuum mechanism to start the siphoning process.
Once you have your siphon hand pump, find a suitable gas can or closed container to collect the gasoline. Place the gas can on the ground, ensuring it is at a lower level than the gas tank of your car. This is important because the siphoning process relies on gravity to pull the gasoline down from the tank into the can.
Now, you're ready to start the siphoning process. Take the hose that comes with your siphon hand pump and place one end into the gas can. Then, carefully insert the other end of the hose into your car's fuel tank. Make sure the end of the hose is pointing down. If your car has an anti-siphon mesh screen or a rollover valve, you may need to use a screwdriver to hold it open or carefully break it to insert the hose.
With the hose in place, start pumping the siphon pump. Most hand-operated pumps only require a few pumps to get the gasoline flowing. Once the gasoline starts flowing, gravity will do the rest of the work. You may need to refer to the instructions provided with your specific siphon pump for any additional steps or considerations.
When you've siphoned the desired amount of gasoline, it's time to stop the flow. To do this, simply raise the end of the tubing or the gas can itself to a level higher than the gas in the tank. This will cause the flow of gasoline to reverse, with any residual gasoline in the pump draining back into the tank.
Finally, remove the siphon pump from the tank. Make sure that the tubing is free of excess gasoline before removing it. Close the gas tank securely, and then safely disassemble and store your siphon pump.
Remember, siphoning gasoline can be dangerous if not done properly. Always exercise caution and follow safety guidelines when working with flammable liquids like gasoline.

Disconnecting the fuel line
- Locate the fuel pump test lead in the engine bay. This is usually found near the fuel tank, often on the underside of the vehicle.
- Disconnect the fuel line: Loosen any clamps or fittings holding the fuel line in place and separate it from the fuel pump. Be careful as the fuel line may be flexible and prone to kinking. Work in small increments to carefully feed and disconnect the line.
- Place a container to catch the fuel: Position a suitable container, such as a fuel storage can or bucket, below the fuel line to catch the draining fuel. Ensure the container is secure and will not tip over.
- Jump-start the fuel pump: With the fuel line disconnected and aimed at the container, jump-start the fuel pump by locating and connecting the fuel pump test lead. This will activate the pump and begin draining the fuel.
- Monitor the fuel level: Keep a close eye on the container as the fuel drains to prevent overfilling. Have someone assist you in watching the container.
- Dispose of or store the drained fuel: Once all the fuel has been siphoned, properly dispose of or store it according to local regulations and safety guidelines.
It is important to note that gasoline is highly flammable, and its vapors are hazardous to breathe. Always work in a well-ventilated area and keep any sources of ignition, such as electronics, sparks, or open flames, away from the vehicle during the process. Additionally, modern vehicles may have anti-siphoning devices and check valves, so be sure to research your specific vehicle before attempting any fuel siphoning methods.

Drilling a hole in a plastic tank
Drilling a hole in a plastic fuel tank is not recommended due to the potential risks involved. However, if you decide to proceed, it is crucial to take the necessary precautions and follow the proper techniques to minimise hazards. Here is a step-by-step guide to help you through the process:
Before you begin, ensure that the tank is empty or contains as little fuel as possible. This is important to reduce the risk of any flammable mixtures that could pose a safety hazard.
Next, gather the appropriate tools and materials. You will need a hand drill, a drill bit of the desired size (for example, 25mm), a Stanley knife, and a hover or vacuum. It is also recommended to have PTFE tape, cork/nitrile gaskets, and a suitable sealant like red hermetyte available.
When you are ready to start drilling, place a plastic dish inside the tank under the drilling spot to catch any falling debris or swarf. You can also use a hover or vacuum next to the drilling area to collect any debris that may fall. Begin drilling with a low-speed setting and a proper hole saw greased to collect the swarf. Cut slowly and carefully to avoid generating excessive heat that could melt the plastic.
Once you have drilled most of the way through the plastic, switch to a Stanley knife to carefully cut the remaining portion. This helps ensure that no debris enters the tank. Clean up any ragged edges left by the drilling process with the knife, being cautious not to generate any debris that could fall into the tank.
After drilling the hole, you must ensure leak-proof connections. Use PTFE tape for tapered thread connections, being careful not to overtighten and split the plastic fittings. Additionally, pay attention to O-rings; overtightening joints can distort them, leading to potential leaks.
By following these steps and taking the necessary precautions, you can drill a hole in a plastic fuel tank while minimising risks and maintaining safety. However, it is always advisable to consult a professional or seek alternative solutions whenever possible to avoid potential hazards associated with drilling into a fuel tank.

Using a valve/fitting on the return line
Modern cars are often equipped with anti-siphoning provisions, such as anti-siphon screens and rollover valves, which can make siphoning fuel challenging. However, there are a few methods you can use to bypass these valves and safely siphon fuel from a car's tank. Here is a detailed guide on how to do it using a valve or fitting on the return line:
Locate the Fuel Line: Find the fuel line, which is usually located near the opening for the car's gas tank. You may need to consult the car's manual or seek advice from a mechanic if you're unsure where it is.
Disconnect the Fuel Line: Before disconnecting the fuel line, place a clean and uncontaminated gas can on the ground near the opening of the car's gas tank. This will be the receptacle for the siphoned fuel. Then, using a special tool or a homemade fuel disconnect tool, carefully disconnect the fuel line.
Attach a Hose to the Fuel Line: Take a clear plastic hose or tube that is about 1 inch (2.5 cm) in diameter, and attach it securely to the end of the disconnected fuel line. Clear tubing is preferable as it allows you to see the gasoline flow, but opaque tubing can also work. Ensure that the hose is long enough to reach from the fuel line to the gas can.
Direct the Hose into the Canister: Place the other end of the hose into your gas canister, making sure that the outlet of the hose remains lower than the inlet to facilitate the siphoning process. This setup will allow gravity to do the work for you, as the gasoline will naturally flow downhill into the canister.
Turn the Car On: With the hose in place, turn the car on. The fuel pump will activate and cause the gas to flow out of the tank and into your canister. You may need to turn the car on and off to keep the gas flowing, and it's a good idea to have someone watching the canister to prevent overfilling.
Control the Gasoline Flow: To regulate the gasoline flow effectively, consider installing check valves at each end of the hose and a shut-off valve in the middle. This setup will enable you to control the flow rate, prevent air from getting into the line, and even allow for long-term fuel storage without the need for re-priming.
Remember, siphoning fuel can be dangerous, and it is always recommended to consult a professional mechanic or a detailed step-by-step guide before attempting any fuel-related tasks.
