How to Siphon Gas

It is no secret that gas prices have been on the rise for years, and show no sign of stopping any time soon. With this in mind, more and more people are looking for ways to save money on gas. One way to do this is by siphoning gas from other vehicles. While this may seem like an illegal or dangerous activity, it can be a great way to save money if done correctly.

JOKING!!!

The siphoning technique is a great way to get fuel from your car or generator in an emergency. The only downside? It’s hard, because car manufacturers have started putting anti-siphoning valves and devices into their cars. In this article, we will discuss the basics of siphoning gas from a vehicle and provide tips for doing so safely and effectively.

5 Simple Steps

1. Open the fuel door: This will allow you to access the gas tank.
2. Locate the siphoning tube: This is the long, thin tube that you will use to siphon the gas.
3. Push the flap aside: When looking at the fuel inlet you will see a small metal flap. You will need to use a screwdriver or something of the sort to move it to the side so you can get your tube into the tank.
4. Put the tube in the fuel tank: Place one end of the tube into the gas tank and put your mouth on the other end.
5. Create suctions: Suck on the tube until you start getting fuel in your mouth. The fuel should continue flowing and can now be placed into a gas can.

Ohh wait! Modern vehicles have an anti-siphon device. Let’s take a look into a few ways you can get around this. Some are easier than others and some are more destructive than others. Depending on the situation you might need to take more dramatic measures.

What Is an Anti-Siphon Valve in a Car?

An anti-siphon valve is a device that car manufacturers install in their vehicles to prevent gas theft. The valve is located in the fuel inlet, and it is designed to prevent fuel from flowing out of the tank. If you try to siphon gas using a tube, the anti-siphon valve will block the flow of fuel.

To prevent you from siphoning gas from a car, there are actually two devices stopping you.

The first is an anti-siphon screen that prevents anything solid coming into contact with the fuel tank and therefore stops any potential flow of liquids or solids going straight to where they don’t want it too! This typically sits higher up near your inlet. And then secondly we have this “rollover valve” which was created specifically to prevent fuel from leaking out in the case of a rollover. It also prevents siphoning of fuel.

3 Methods to Bypass the Anti-Siphon Valve

Parking on a Slope

The anti-siphon screen is usually located quite far down the neck of the fuel inlet, which means you can probably get most if not all gas with this simple trick. Just park on a steep slope and a good amount of the fuel will make its way into the inlet neck above the anti-bypass valve, allowing you to siphon off the fuel. You might not get a lot, but something is better than nothing.

Break the anti-siphon screen

You can break the anti-siphon screen but this is something we don’t recommend. You’ll do this by taking something that is long and sharp and sliding it down the inlet neck. One problem! Metal on metal will create a spark and the last thing you want is a spark while messing around with fuel. The solution. Use copper. Copper is a highly conductive metal meaning it oftentimes won’t create a spark. You can use copper wire but you’re better off using a copper ring attached to the end of your pipe. Not the best solution but a solution nonetheless.

Disconnect fuel line and drain fuel

Disconnecting the fuel line is a bit more work then you might think but if you need fuel the extra work will be well worth it. Follow these steps:

• Find the fuel line
• Disconnect the fuel line: Disconnecting the fuel line is a bit more work then you might think but if you need fuel the extra work will be well worth it. All you need is a fuel line disconnect tool for this, which you can make yourself.
• Place a hose on the end of the fuel line and place the other end of the hose in whatever container you’re using to collect the fuel in.
• Now you need to turn the vehicle on and off and this will cause the fuel pump to kick on and off. Due to this the fuel will flow and then stop, thus the continuous turning on and off of the vehicle.
• If you don’t have the ability to turn the vehicle on and off you can jump the fuel pump relay. This might not work for all vehicles but in a desperate situation it’s worth a try.

Your Final Option (Not Recommended)

Drill a hole in the gas tank: This is your last option and arguably the worst. Drilling can cause sparks and those sparks can easily cause the fuel tank to explode. This is really only a good option if you’re drilling into a fuel tank that is made of plastic. This will also completely destroy the fuel tank so keep that in mind.

Another thing you need to take into consideration is the fact that vehicle fuel tanks hold a lot of fuel, so if you’re only looking to get a small amount of fuel this might not be the best option. You could easily be wasting a dozen gallons or more of fuel it you don’t have the means of capturing it all and storing the access fuel away long-term. Also keep in mind that once you have all this fuel you need a way to keep it from going bad so make sure you find out how to make you gas last longer!

TIPS:

-If you are going to siphon gas from another vehicle, be sure to choose one that is older and doesn’t have an anti-siphon valve installed.

-Always siphon in a well-ventilated area, as gasoline fumes can be dangerous.

-Be sure to use a clean siphoning tube, as dirt and debris can clog the fuel line.

-Never siphon gas from a car that is running, as this could be extremely dangerous.
