The risk of getting a mouthful of gasoline is simply too great. A squeeze-bulb type siphon will make the job a lot easier. Unless you are trying to siphon gas from a really old car, chances are that it has an anti-siphon device. You will need to bypass this if you want to get fuel out of the tank. There are actually two devices that can prevent you from siphoning gas from a car. The first is an anti-siphon screen. It is a mesh screen that prevents you from putting anything solid into the gas tank.
This is typically located higher up in the fuel filler pipe. This valve is actually meant to keep gas from escaping the car in event of a rollover but it also prevents you from sticking a siphon hose in the tank — hence why it is often called the anti-siphon valve. If the car has an anti-siphon screen but does not have a rollover valve, then you can probably siphon most of the gas with this simple trick. It works because the anti-siphon screen is usually located quite far down the neck of the fuel filler pipe.
Just park the car on a steep slope so the filler is downhill. Your siphon hose will be able to reach some of the gasoline to siphon it out. It is possible to break through the anti-siphon screen in a car. The problem is that metal-on-metal can create a spark. And a spark could result in a massive fire! A good solution is to use copper. Because copper has high conductivity, it generally will not create sparks. One solution is to make a copper ring and solder it to a copper pipe.
You then feed the pipe into the fuel filler tank and use the ring at the end to break the screen. Car rollover valves allow gas to enter the tank in one direction only.
I have some tubing from a refrigerator we bought a while back. Think I will try it. Nice Disclaimer. My fuel pump went out right after I filled up my tank. In order for me to replace the pump, I have to drop the fuel tank, which meant I had to drain the tank first. After trying a garden hose, I took your suggestion.
The important part is cutting the end to a sharp point. Thanks for the info! Hmm, that was interesting. You could just walk away and come back later. Having a longer hose, and putting the gas can all the way on the ground, would help because it would give more gravity to the situation.
Oh, and the hardware store is full of cheap hoses of all different diameters. I just bought one for my aquarium protein skimmer. The old one got aged and stiff.
Though the experience of having gas stolen from my gas tank while I had the vehicle in storage, I found out that there is a connection to the gas tank of a Odyssey that can be disconnected to drain the gas tank. How did you drain it? Does it have a capless gas tank, thos have anti siphon filters. The pipe that connect to the fuel injector is easy to disconnect safely. You need to put the container close, which mean above the level in the gas tank. The gas pump will run for 2 seconds.
Turn key to off, then run, you get another 2 second worth of gas. Repeat until you fill your container. A more efficient method would be to identify the relay for the fuel pump, remove it from the socket and insert a wire between the pin that correspond to the relay contact. The fuel pump would work continuously. Be very careful doing that. All fuel pumps are lubricated by the fuel itself.
I taper the end of the hose an d still having a problem. I think Fords use something like a butterfly system instead of the ball. Once gas is freely flowing from the tank into the can, you don't need to continue blowing - gravity will do the rest of the work. When you want to stop siphoning gas, cover the long tube with your thumb, raise it above the level of gas in the engine, and remove your thumb.
Any remaining gas in the tube should flow back into the tank. You're finished. Remove your tubes and close the gas tank. Air needs to be able to escape the tank to make space for the gas flowing back in. Method 2. Buy or obtain a siphon pump. These pumps come in a wide variety of shapes and sizes - some are automatic, while others are hand-powered.
However, the vast majority function similarly: a pump in the middle of a length of tubing creates suction which pulls liquid from one end of the tubing to the other.
As such, they're ideal choices for cautious-minded individuals. Place a gas can on the ground beneath the tank and run the tubing from the tank to the can. Like the other methods described in this article, suction only provides the initial force necessary to start the siphon.
After gas begins flowing, gravity does the rest of the work. Because of this, it's crucial for the receptacles to be below the level of gas in the tank. Note: siphon pumps have one designated end that liquid enters and another end from which liquid leaves. Ensure that the correct ends of the tubing are being used. If arranged backwards, the pump will simply push air into the gas tank. Pump when ready. Because siphon pumps work in a wide variety of ways, the exact action you'll need to take here may vary.
If you have a hand-operated pump, you may need to grab a plunger and push in and out or squeeze an inflatable bulb. If you have a mechanical pump, you may just need to flip a switch. Automatic pumps may or may not need to be left on throughout the pumping process.
Consult any instructions provided with your siphon pump for more information. When you near your desired stopping point, raise the end of the tubing or the container itself to stop the flow. Raising the end of the tubing to a level higher than that of the gas in the tank cause the flow of gas to reverse, so any residual gas in the pump should drain back into the engine. If using an automatic pump, you may need to turn it off at this point. Remove the siphon pump from the tank.
When the tubing is free of excess gas, you may safely remove it from the gas tank. You are finished. Close the gas tank and seal the gas can, then safely disassemble and store your siphon pump. Some siphon pumps need to be cleaned after use. Consult any provided instructions for more information - often, all that's necessary is to pump a mixture of soap and water through the device and let it air dry. Method 3. Understand the danger of gasoline poisoning.
Gasoline contains numerous chemical compounds called hydrocarbons which are poisonous to humans. If attempting this method of siphoning, take every possible precaution to ensure you don't swallow any gasoline or breathe in any vapors. If you've been exposed to gasoline in any way and begin to exhibit symptoms, call the emergency services or your local poison control central immediately.
Obtain clear tubing that is 1 inch 2. As with the method above, this method requires a length of tubing and a receptacle to contain the siphoned gas. As above, it's important to use a closed gas canister to prevent gas from being spilled or fumes from being inhaled.
However, with this particular method, clear tubing is not merely recommended, but rather, crucial. Because ingesting gas is hazardous to your health, you need to be able to able to see the gas moving through the tube so that you can take the tube out of your mouth before gas reaches it.
Feed one end of the tubing down into the vehicle's gas tank. Set your gas can on the ground near the vehicle's gas tank. Feed one end of the tube into the tank deep enough that it sits below the surface of the gas into the tank. To tell whether the tube sits below the gas, blow air into the other end taking care not to inhale fumes through the tube as you do so and listen for the sound of bubbles.
Place the free end of the tubing in your mouth. This method of gas siphoning works by using your mouth to create suction in the tube, which draws gas out of the tank.
Once gas is flowing freely, gravity causes the siphon to continue sucking gas out of the tank. Care must be taken to ensure you don't swallow any gas or inhale any vapors. Once the tube is in your mouth, breathe only through your nose and pay close attention to the level of gas in the tube. Keep your fingers around the tubing near your mouth so you are ready to crimp it before gas enters your mouth.
Once you start sucking on the tube, gas may begin flowing quickly. Keep one hand ready to stop the flow of gas so that none gets in your mouth. Suck on the tubing and watch the gas flow into the tube. To minimize but by no means eliminate the risk of gas vapor inhalation, try to suck with your mouth, rather than your lungs - as if you are drawing on a cigar, rather than a cigarette.
When gas begins flowing through the tube, it can flow somewhat quickly, so be alert. When the gas is about six inches from your mouth, crimp the tubing tightly near the end and remove it from your mouth.
Check for air bubbles in the tubing. Air bubbles are a common hindrance when siphoning gas, as they can impede proper flow, forcing you to suck harder, which is dangerous. If you see air bubbles in the tubing, release the crimp and drain the gas back into the car, then try again.
Try to position the tube so that you're sucking directly above the tank. According to some sources, air bubbles are more common when the tube runs to the side, rather than up and down. Stick the end of the tubing into the gas can and release your crimp.
