Can fuel be siphoned from a car's gas tank using a tube?

[DiMadelyn]

Fuel cannot be siphoned from a car's gas tank using a tube. Modern car fuel tanks are equipped with filters, making it nearly impossible for a tube to enter the tank, let alone extract fuel. This design is also intended to prevent fuel theft. The one-way valve design in the fuel filler neck is structured to facilitate quick refueling, typically featuring a larger diameter. The fuel pump is located inside the tank, with its top sealed and connected to the tank's upper part. The low-pressure fuel line and return line are connected above the fuel pump. When the fuel pump is inactive, there is no direct connection between these lines and the tank, ensuring that even in the event of an accident, fuel will not leak out.
