How To Remove Anti Siphon Valve
After a natural disaster, you need gas for your generator. You know the gas tank in your vehicle is full. How exercise you bypass the anti-siphon device in the filler tube? There is a way to become around the anti-siphon valve, merely it can be tricky and volition non work on some vehicles.
Fuel system engineering and safety devices take made gas tanks nearly impervious to tampering. We will look at two means to bypass the anti-siphon device installed in a modern car and so some other viable options if the traditional siphoning methods don't piece of work.
What Is the Anti-Siphon Valve?
The fuel fill up tube of nearly vehicles produced today includes a rollover valve, also known as an anti-siphon valve. Anti-siphon valves prevent back-flow, relieve tank pressure, and block the gas from spilling out of the gas tank in the event of a rollover.
A plastic brawl is retained by a fix of clips at the end of the filler tube. Since the brawl is always in place simply below the filler tube's finish, information technology tin besides prevent gas siphoning.
The Safest Way to Featherbed the Anti-Siphon Valve
Yous should be able to slip a small plastic tube through the valve if you have the right tools. To attempt this method, you volition demand the following items.
Required Components:
- 4 feet of three/eight inch ID Polyethylene tubing
- 6 feet of .170 inch ID x i/4 inch OD Polyethylene Tubing
- A sharp pocketknife or tubing cutter
- Gas prophylactic pump
Polyethylene tubing is used for a siphon hose instead of vinyl tubes. The poly is flexible but relatively potent. Vinyl is too soft for this project.
Utilise a 12-volt electric or manually operated fuel safe pump. Utilize the 0.170-inch tube equally the siphon tube. It will take hours to transfer fuel with the small tube by gravity. Also, you do not desire to suck gas into your mouth if you tin avoid it.
The Procedure for Bypassing Car's Anti-Siphon Valves
Disclaimer: these are general guidelines! What y'all exercise to your ain vehicle is your own responsibleness. We are only sharing one style to practise this to a vehicle you legally own.
Install the Guide Tube
Slide the 3/8 inch tube down the filler tube. The tube should be stiff plenty to push the upper seal open. If non, use a long, thin screwdriver to push the seal open. Slide the tube down as far as it volition get. Y'all may demand to rotate the tube to reach the end of the filler tube.
Install the Siphon Tube
Cut the lead end of the siphon tube at a 45-degree bending. The pointed end volition assist in slipping past the valve. Slide the siphon tube down within the guide tube.
When the siphon tube reaches the ball, pull the guide tube back an inch or two. Go along pushing and rotating the siphon tube until it slips past the ball.
Testing for Fuel
Blow through the siphon tube if you suspect it has slipped past the ball. You volition hear bubbling and experience resistance if the tube has reached the fuel tank. When you reach the fuel, slide a pes of tubing into the tank.
How To Siphon Gas
You tin at present attach the pump to the siphon tube and depict gas out of the tank. Place the discharge end of the pump in a gas tin can before starting the pump.
Pull the siphon and back up tubes from the tank when finished. Removal may require some back and forth move equally the brawl may compression the tube.
Another Way to Bypass Anti-Siphon Valves
This method is similar to the outset process. The master drawback is that it is destructive and may outcome in a damaged filler tube. Avoid this method unless absolutely necessary. If you are in astringent need of gas, it is a viable option.
Required components:
- 2 feet of 1/2 inch flexible copper or aluminum tubing. Practise not utilise steel.
- If your automobile'south filler tube is straight enough, 1/2 inch PVC pipage will work
- Regular siphoning kit
The Procedure
Insert the metal tube into the gas filler tube. Do not employ steel due to the chance of making a spark. Work the tube downward the filler tube until you lot accomplish the anti-siphon valve.
Pushing the tube should dislodge the brawl or break the retainer clips that concord information technology. If you can not button the ball loose, strike the end of the tube with a hammer, as this may dislodge the ball.
Siphon Gas
If you dislodge the ball, remove the metal tube. You can now insert your regular siphon tube and remove the fuel. Utilise a 12-volt or hand pump to depict out the gas.
If you employ a gravity system, use a bulb to describe the fuel out of the tank to first the gas flowing.
Other Means of Siphoning Fuel From Your Car
Sometimes the traditional siphoning methods won't work, so hither are a few boosted options.
Siphoning a Machine's Fuel Pump
Many modern passenger cars have fuel pump access panels in the trunk or under the back seat. Removing the electric fuel pump is an easy mode to siphon the gas from your vehicle. Some cars, and most pickup trucks, do not have easy admission to the fuel pump. Even if yous demand to piece of work nether the vehicle to remove the pump, it may be a better selection than breaking your anti-siphon valve.
If your vehicle does have a fuel pump access panel, the process is straightforward.
- Disconnect the negative bombardment terminal
- Remove the access panel
- Brand a note or take a moving-picture show of the connections before proceeding.
- Disconnect electric connections and fuel lines
- Remove the fuel pump
Y'all now have clear admission to the fuel tank. Afterwards siphoning the gas, replace the pump. It may exist wise not to reconnect everything if you suspect you will need more gas before you demand the auto.
Farthermost Situations
Siphoning may not be feasible on your vehicle. A good mechanic could add a valve to some other portion of the fuel system. A valve installed in the fuel line or the tank itself may be an option. Such additions are non recommended but are a potential solution.
Does siphoning gas injure your automobile?

Can you use a garden hose as a siphoning tube?
A garden hose is non a expert selection for siphoning gas. A garden hose is non rigid and will kink. This will impede the flow of gas and could cause the hose to burst. A garden hose is also more probable to create a spark, which could ignite the fuel vapors in the tank.
Is an anti-siphon screen the aforementioned thing equally an anti-siphon valve?
An anti-siphon screen is a mesh that is placed over the fuel filler neck. This screen is designed to forestall debris from entering the tank and clogging the fuel filter. It does non serve the same purpose every bit an anti-siphon valve, which is designed to keep fuel from being siphoned out of the tank.
Determination
"Zilch is as easy as it should be" is a phrase that comes to mind when trying to siphon fuel from your auto's gas tank. While there are methods to do it, success is contingent on the design of the fuel filler tube and the anti-siphon device. If yous suspect you lot may demand to attempt siphoning gas from your vehicle someday, it would exist wise to examination the preferred method before that mean solar day comes. Practice is oftentimes part of being prepared.
