How to Extract Fuel from a Car?

To extract fuel from a car, follow these steps: 1. Prepare the necessary tools, including a flat-head or Phillips screwdriver, pliers, a plastic tube approximately 1cm in diameter, a wire, and a container for the gasoline; 2. Open the engine compartment hood and locate the fuel lines connecting the engine and the fuel tank. There are usually three lines: one supply line, one return line, and one carbon canister line. If the owner cannot distinguish between the three lines, all three can be disconnected, and the plastic tube can be connected to the gasoline container; 3. Next, open the vehicle's relay box, locate the fuel pump relay, remove it, and use the wire to short-circuit the 85 and 86 sockets on the relay socket. The relay box cover will have markings, making it easy to identify; 4. Insert the car key and turn it to the "ON" position. For vehicles with a push-button start, press the start button without pressing the brake pedal. Once activated, gasoline will flow out of the fuel line; 5. When the container has collected a sufficient amount of fuel, the owner can turn off the ignition, remove the short-circuit wire, reinsert the fuel pump relay, and finally reinstall the disconnected fuel lines to their original positions.
I often help friends siphon fuel from cars, mainly for emergencies or when switching vehicles. Park the car on level ground and turn off the engine, waiting for it to cool to avoid burns. Open the fuel tank cap and use a clean, transparent plastic tube (about 1cm in diameter), inserting one end into the bottom of the fuel tank below the fuel layer and the other end into a container placed lower. Never use your mouth to suck! It’s dangerous as you might accidentally inhale gasoline—instead, use a dedicated hand pump. After inserting the tube, press a few times to start the siphon. Ensure good ventilation throughout the process, with no open flames or cigarettes, and wear gloves to prevent splashes. The fuel tank might have an anti-siphon design, so don’t insert the tube too deep to avoid getting stuck. Once the fuel starts flowing, keep the tube opening lower than the fuel tank to maintain the siphon. After siphoning, wash the tube with soapy water to prevent residue contamination. With a few practices, you’ll get the hang of it, but always follow local regulations and avoid improper disposal of fuel. Safety first—check the fuel quality each time. Simple tools are sufficient; professional equipment isn’t always necessary.
When siphoning fuel, I prefer to start with simple steps to ensure my safety and that of the environment. Park the car in a shady, flat area and let the engine cool for at least 20 minutes. Prepare an empty gasoline can and a hose—avoid using one that’s too thin to prevent clogging. Insert the hose into the fuel tank slowly to avoid damaging anything. The best way to start the siphon is with a mini hand pump, which costs just a few dollars and can be found at supermarkets. Press the pump a few times, and the fuel will flow out—much safer than using your mouth. Keep the area well-ventilated throughout the process, stay away from open flames, and wear old clothes to protect against spills. After siphoning, clean and store the hose properly, and store the fuel carefully to avoid waste. If you don’t have a pump, you can use gravity by blowing air into the hose and quickly moving the can to start the siphon. In short, stay calm and patient—safety always comes first. This method is highly practical, especially when moving fuel for relocation or camping trips.
