The method for extracting gasoline from a car is: 1. Open the engine hood and locate the fuel line connecting the engine to the fuel tank; 2. After removing the fuel line, connect a plastic tube to a container; 3. Open the vehicle's relay box and unplug the fuel pump relay; 4. Connect wires to the relay socket; 5. Insert the key into the ignition switch and turn it to the ON position to start siphoning the fuel. The working principle of extracting gasoline from a car is: The power unit provides power, which is converted from high-speed operation to low-speed operation of the oil pump crank through a reducer. The crank, connecting rod, and walking beam mechanism then convert the rotational motion into reciprocating motion of the oil pump, driving the piston in the oil pump to extract crude oil.
To extract gasoline from a car, I always keep a hand-operated pump tool handy—it's simple and safe to use. First, find a spacious and well-ventilated area, ensuring the car is turned off with no open flames or sparks nearby. Prepare a gasoline-specific hose and a clean container. After unscrewing the fuel tank cap, slowly insert the hose and start pumping the handle—the gasoline will flow through the hose into the container. This method is effortless and affordable, with a full set costing just a few dozen yuan on Taobao, making it ideal for draining old fuel for replacement or storage. Remember to wear gloves and a mask throughout the process, as gasoline is highly volatile—avoid inhaling too much. Don’t dump the extracted fuel on the roadside to avoid pollution; take it to a waste oil recycling station. The whole process takes about 20 minutes, and you’ll get the hang of it after a few tries, though beginners should have a friend supervise. Clean the tools after each use to prevent residue buildup—this ensures efficiency and environmental responsibility.
When extracting gasoline, I prioritize safety and environmental protection, and recommend the siphon method as it's simpler. Insert a transparent plastic hose gently into the fuel tank, place the other end into a metal container, and give it a strong suck to start the flow—but never swallow! Alternatively, using your mouth through gauze is safer. Always operate in an open space to avoid vapor accumulation and wear goggles for eye protection. Gasoline is toxic—never dispose of it carelessly. Store it in sealed containers and take it to recycling points to minimize pollution. I personally only use this method when accidentally refueling with lower-octane gas, and gravity drainage is even safer. A tip: check the weather forecast to ensure no rain during the process, reducing the risk of gasoline moisture degradation. Patience is key, and beginners will get the hang of it after a few tries. Safety first, respect nature.
