How to Drain Gasoline from a Sedan?
2 Answers
To drain gasoline from a sedan, follow these steps: 1. Drive the vehicle onto a steep slope, then turn off the engine and engage the handbrake. This is because the car's fuel tank has a U-shaped bottom, making it difficult to drain fuel on flat ground. 2. Open the fuel tank and insert a plastic hose. 3. Place the other end of the plastic hose in your mouth and suck hard, being careful not to get gasoline in your mouth. 4. Once you see the gasoline flowing, place the end of the hose into a container and let it drain naturally. Gasoline is refined from various petroleum-derived components such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline, blended with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.
I've been fixing cars for almost twenty years and have seen many people try to siphon gas themselves. I really don't recommend doing this. First, you'll need a long hose and a manual fuel pump. Open the gas tank cap and insert the hose, but be careful not to get it stuck on the anti-siphon screen. Older cars might have a drain plug at the bottom of the tank—just unscrew it to drain. However, modern cars have eliminated this design. If you absolutely must do it, first disconnect the negative battery terminal, locate and remove the fuel pump relay, start the engine and wait for it to stall to release pressure, then disconnect the fuel supply line in the engine bay and attach a hose. Gasoline is like flowing gunpowder; a single spark can cause an explosion. Don't use your phone while siphoning, wear cotton clothes to prevent static, and ground any metal containers. My advice? Just go to a repair shop and pay them to handle it with professional tools—it's the safest way to avoid burning down your garage.
