Here's why:
* Legality: Siphoning gas from a vehicle you don't own is theft, a serious crime with potential legal consequences. Even siphoning from your own vehicle in certain circumstances (e.g., to avoid paying for gas) might have legal ramifications.
* Danger: Gasoline is highly flammable and inhaling its fumes can be harmful or fatal. Siphoning involves working near a source of ignition (the engine, electrical components, etc.) A spark could easily cause a fire or explosion. Furthermore, improperly siphoning can introduce contaminants into your fuel system.
In short, don't do it. If you're out of gas, call a friend, family member, or roadside assistance. If you need gas for your vehicle, purchase it legally at a gas station.
