What happens if a car starts while being fueled?

Ripping the hose does not cause explosions, but it is good to repay the post.

The scene has already been explored in some comedy movies: the driver stops at a gas station and, in a hurry or inattention, plucks the car with the fuel pump hose still attached to the vehicle's tank inlet. In the cinema, this situation yields funny and even dangerous scenes, such as an uncontrollable fuel leak. But in real life, engineers predicted this could happen and designed the equipment the right way.

First of all, good news: According to the Mental Floss website, there will be no explosions or fireballs. The hose that connects the fuel pump to the nozzle is designed to break in two parts if a certain amount of force is applied to it. When you go to the station again, look for a metal coupling on the hose, as this is where it should break.

As soon as the hose bursts and the driver drives the car absently, check valves inside the pipe block the liquid and prevent fuel from being spilled out on the road. However, the gas station management is very likely to expect the driver to pay for the damage caused.
