Solution for pumping oil from the car fuel tank:
First find the car's filter, and find the gasoline filter next to the fuel tank (only for cars with gasoline filters), because the oil ports of ordinary cars now have anti-pumping rubber nets and no screws to drain oil. So you can start with the filter element, find a tube on the filter element of the car, and open the key of the car (the key of the ignition lock is set to the ON position, which is the position before the ignition of the car), but note Do not start the car, and then you can hear the sound of the car's oil pump working, so if you repeat this several times, the oil in the car's fuel tank will come out through the pipe. (This method is highly dangerous and may damage the gasoline pump, please use it with caution)
Automobile fuel tank pumping method 2
Use the siphon principle to insert the tube directly into the gasoline at the filter element mouth
Siphoning is a hydrodynamic phenomenon that can draw liquid without the aid of a pump. After the liquid in the upper position fills an inverted U-shaped tubular structure (called a siphon), it opens in the lower position. Under this structure, the liquid pressure difference at the two ends of the tube can push the liquid past the high point and discharge to the other end. The siphon works mainly by gravity
Dr Stephen Hughes of Quinlan University of Technology in Australia said: "The liquid in the siphon is moved from the upper end to the lower end by gravity. Lead from the top to the bottom. "
Automobile fuel tank pumping method 3
Now technology is more developed. Some car maintenance companies have invented a gasoline recovery device that pumps gasoline. The operation method is very simple.
Because thieves will also use this method to steal oil, manufacturers now treat the fuel tank in one direction when manufacturing vehicles, allowing only gasoline to be poured in and out of order. Therefore, this method cannot extract the fuel from the fuel tank.
