How to siphon gasoline from a car fuel tank?

[Gandalf]

Methods for siphoning gasoline from a car fuel tank: 1. Drive the vehicle onto a steep slope, then turn off the engine and engage the handbrake. Since the bottom of the fuel tank is U-shaped, it's difficult to drain oil on flat ground; 2. Open the fuel tank and insert a plastic hose; 3. Put the other end of the plastic hose in your mouth and suck hard, being careful not to get gasoline in your mouth; 4. Once you see gasoline coming up, place the end of the hose into a container and let it drain naturally. Precautions for refueling: 1. Don't wait until the fuel warning light comes on to refuel; 2. Choose to refuel in the morning or evening; 3. Avoid filling the tank completely when driving in the city; 4. Don't refuel during thunderstorms.
