To significantly *reduce* the amount of fuel, you have several options, none of which will get it completely empty:
* Drive it down: The simplest way is to simply drive the car until the fuel gauge shows empty. However, this isn't a guaranteed method to get the absolute lowest amount out, and running a car completely out of gas can damage the fuel pump.
* Siphon: This is a risky method and should only be attempted if you know what you are doing and understand the associated safety hazards (explosive vapors!). Use a siphon pump designed for liquids, and never use your mouth. Even then, you won't get everything out.
* Professional draining: A mechanic or auto repair shop can drain the tank using specialized equipment. This is the safest and most effective way to remove a significant amount of fuel, though it will likely still leave some residual fuel.
Important Considerations:
* Safety: Gasoline is highly flammable. Always work in a well-ventilated area, away from any open flames or sparks. Static electricity can also ignite gasoline vapors.
* Legality: Improperly handling or disposing of gasoline is illegal in many areas. Check your local regulations before attempting to remove fuel from your vehicle.
* Environmental impact: Spilled gasoline contaminates the environment. Take precautions to prevent spills.
If you need to completely empty the tank, it's best to contact a professional mechanic. They have the tools and knowledge to do it safely and legally.
