Siphoning petrol is the process of transferring fuel from one container to another using a tube or hose. This can be a useful skill to have in case of an emergency, such as when you run out of petrol and need to get to a petrol station. It can also be used to transfer petrol from one vehicle to another.
There are a few different ways to siphon petrol, but the most common method is to use a siphon hose. A siphon hose is a flexible tube with a weighted end. The weighted end is placed in the fuel tank of the donor vehicle, and the other end is placed in the fuel tank of the recipient vehicle. The petrol will then flow from the donor vehicle to the recipient vehicle due to the difference in air pressure between the two tanks.
