What You'll Learn
Use a hose and pump to suck out bad gas
To drain bad gas from your fuel tank, you will need about six feet of small ⅜-inch hose, as well as a pump to draw the fuel out. Do not attempt to siphon the gas out with your mouth, as this is hazardous to your health. You could swallow gasoline or spill enough to create a serious fire hazard.
First, locate your fuel tank. If you can detach the lines and/or small drain plug directly, this is the easiest way to drain the tank. Place a pan or receptacle underneath the drainage plug to catch the fuel. If your car is a newer model, it may have a protective metal bulb or screen that prevents gas from escaping in a crash, so you will need to devise a new strategy.
Stick your hose into the gas tank, feeding it until there is only one to two feet left before the pump. You can also use the fuel lines, which are small, removable hoses underneath the tank. However, you must turn the car on and off repeatedly to force the gas out of the tank, as it uses the electric fuel pump to do so.
If your vehicle has a saddle-type fuel tank, you may need a specialised way to remove the fuel from both sides of the tank. Seek a professional's help to get all the fuel out.

Drain plugs can be used to empty fuel tanks
If you've filled your car with the wrong type of fuel, you'll need to drain the fuel tank to avoid serious damage to your engine. Fuel can also go bad if it's been sitting in a tank for too long, so it's important to drain and replace the gas before driving an old car that's been sitting in storage.
One way to drain a fuel tank is by using a drain plug. Not all vehicles will have a drain plug, but if yours does, it's usually located near the bottom of the fuel tank. To remove the drain plug, you'll need a spanner or socket wrench. Place a pan or receptacle underneath the drainage plug to catch the fuel, then unscrew the drain plug and let the fuel drain out. This process can take a long time, up to several minutes per gallon, so be prepared to catch all the drained fuel and make sure none is spilled onto the ground.
If your vehicle doesn't have a drain plug, you can use the fuel lines to drain the tank. The fuel lines are small, removable hoses underneath the tank. To use this method, you'll need to turn the car on and off repeatedly to force the gas out of the tank using the electric fuel pump.
Another option for draining a fuel tank is to use a hose and a pump to draw the fuel out. Simply stick the hose into the gas tank and use the pump to draw the fuel into a container. This method can be hazardous if not done properly, as it carries a risk of inhaling toxic fumes or spilling fuel.
For certain types of vehicles, such as Caterpillar Haul Trucks and Wheel Loaders, you can purchase specialised drain plugs made of durable and corrosion-resistant stainless steel. These drain plugs allow for easy maintenance and can be used to drain water condensation from the bottom of the fuel tank without having to completely drain the fuel.

Fuel lines can be removed to force gas out
If your car has been sitting idle for a long time, it's a good idea to drain and replace the gas to ensure that everything runs smoothly. This is because fuel can go bad when left sitting in a tank for too long.
One way to drain the gas from your fuel tank is to remove the fuel lines and force the gas out. The fuel lines are small, removable hoses located underneath the tank. To do this, you will need to turn the car on and off repeatedly to force the gas out of the tank, using the electric fuel pump. Make sure you have enough drain pans to catch all the drained fuel and avoid any spills.
It is important to note that not all vehicles will have a drain plug. Some vehicles have a fuel test port under the hood, which can be used to drain the fuel with a special tool. This will require turning on the fuel pump while the engine is not running.
If you are having difficulty removing the fuel lines, there are a few tips that may help. Firstly, make sure you are working in a well-ventilated area away from sources of ignition, and take care not to damage the fuel lines or connectors. You can try using a fuel line disconnect tool, which can be found online or at an auto parts store. These tools come in different sizes, so make sure you get the right one for your vehicle. If the plastic disconnect tools are not working, you can try using fuel line pliers, which are designed specifically for removing threaded fuel lines without damaging them. Another method is to apply penetrating oil to the threaded connectors to help loosen them, letting the oil sit for a few hours or overnight.

Fuel testers can drain gas through the test port
Some vehicles have a fuel test port under the hood to which a fuel tester can be attached and used to drain the fuel. This method requires turning on the fuel pump while the engine is not running by jumping the fuel pump relay or using a scan tool. It is important to note that not all fuel tanks can be drained directly, and the process may vary depending on the vehicle model.
Fuel testers, also known as fuel sumpers or fuel checkers, are commonly used in aircraft to check for fuel contamination, which is a leading cause of engine failure. The testers are designed to fit all major aircraft fuel drain valves and provide a direct readout, making the testing process easier and reducing the chance of fuel spillage, probe breakage, and fuel contamination.
There are different types of fuel testers available, such as the longer model with a screwdriver at one end, which is convenient for opening a cowling during pre-flight. The center rod is removable to accommodate both types of drain valves. Some models also have flippable or removable pieces. Another type of fuel tester is the GATS Jar, which has a larger capacity and can be used with larger aircraft. The GATS Jar has a reversible piece that can activate the fuel drain and fit both types of valves. It also incorporates a screen that allows you to strain out debris and pour the sumped fuel back into your tank if desired.
When using a fuel tester to drain fuel through the test port, it is important to have a pan or receptacle underneath the drainage plug to catch the fuel. It is also recommended to gauge the amount of fuel in the tank beforehand to ensure you have enough containers to catch all the drained fuel. Additionally, make sure that the fuel tester is properly installed and secure to prevent leaks or potential dangers.
