 Solution for pumping oil from car fuel tank:
First, you need to find the filter element of the car. Next to the fuel tank, find the gasoline filter element (only for cars with gasoline filter elements installed externally). Because nowadays, most cars have anti oil suction rubber and no oil drain screws, you can start with the filter element. Find a pipe and place it on the filter element of the car. Turn on the car key (the ignition lock key is turned to ON, which is the gear before starting the car), but be careful not to start the car. Then you can hear the sound of the car's oil pump working. Repeat this several times, and the oil in the car's fuel tank will come out through the pipe. (This method is highly dangerous and there is a risk of damaging the gasoline pump. Please use it with caution)
Method 2 for pumping oil from car fuel tanks
Using the siphon principle, directly insert the pipe into the gasoline at the filter cartridge port
Siphon is a fluid dynamics phenomenon that allows for the suction of liquid without the need for a pump. After filling a inverted U-shaped tubular structure (called a siphon) with liquid at a higher position, it opens at a lower position. Under this structure, the pressure difference between the liquid at both ends of the pipe can push the liquid over the high point and discharge towards the other end. It is mainly due to the gravitational force that makes the siphon tube work
Dr. Stephen Hughes from Queensland University of Technology in Australia once said, "It is gravity that causes the liquid in a siphon tube to flow from the upper end to the lower end, using the longer and lower end to draw the water from the shorter upper end upwards and then flow to the lower end
Method 3 for pumping oil from car fuel tanks
Nowadays, technology is relatively advanced, and some car maintenance companies have invented gasoline recovery devices specifically for extracting gasoline. The working method is very simple, and the oil is also extracted from the filter cartridge of the gasoline
