Draining gas from a car is the process of removing the gasoline from the fuel tank. This may be necessary for a variety of reasons, such as when the car is being stored for an extended period of time, when the fuel system is being serviced, or when the gas has gone bad.
There are two main methods for draining gas from a car: using a siphon hose or using a fuel pump. Using a siphon hose is the most common method, and it is relatively simple to do. To use a siphon hose, simply insert one end of the hose into the fuel tank and the other end into a gas can. The gas will then flow from the fuel tank into the gas can.
