What You'll Learn
Anti-syphon devices slow fuel flow into the tank
Anti-syphon devices are installed in fuel tanks to prevent accidental fluid leakage. This is particularly important when the tank is stopped, as fluid leakage can still occur in these instances. For example, a fuel or diesel tank with a shut-off pump and a dispensing tube that is badly positioned or on the ground can be emptied due to the hydrostatic pressure of the fluid within the tank.
Anti-syphon devices work by interacting with the physical properties of the fluid and acting as a vacuum breaker to prevent leakage. They are installed in a vertical position at the highest point in the suction line, with no part of the line between the valve and the tank below the maximum fuel storage level. This ensures that an additional vacuum is created by the fuel pump, lifting the poppet and opening the valve.
The installation process for anti-syphon devices varies depending on the make and model of the vehicle. For example, some vehicles may have an anti-syphon valve in the fuel filler hose, while others may have a plastic screen and trapdoor mechanism.
It is important to note that anti-syphon devices may slow down the fuel flow into the tank. This is because the anti-syphon device creates an additional vacuum, which can affect the rate at which fuel can enter the tank. However, this is a small price to pay for the added security and safety that anti-syphon devices provide.
Anti-syphon devices are an inexpensive and effective solution to prevent fuel theft and accidental spills, reducing fire hazards and ensuring compliance with various fire protection codes and safety standards.

Thieves are drilling holes in tank bottoms
As fuel prices have increased, thieves have begun drilling holes in fuel tanks to steal gasoline, as traditional siphoning methods have become more difficult. This new method of fuel theft is quicker and more effective for thieves. However, there are several anti-siphoning devices and precautions that can be used to prevent fuel theft.
A locking fuel cap can be used as a deterrent, as it spins and requires a key to open, making it harder for thieves to access the fuel tank. Additionally, parking in secure locations, such as a garage, well-lit areas, or fenced lots, can reduce the risk of fuel theft. Vehicle owners can also install anti-siphon devices, such as those with internal stainless steel mesh and unaligned baffle plates, which prevent access to the fuel through small holes. These devices are made from strong materials like Domex or Armour plates, making them resistant to drilling and physical force.
While these measures can help deter thieves, it is important to note that no method is entirely foolproof. As Vince Fiori, owner of Fiori Auto Repairs, points out, "If a thief wants it bad enough, they know ways to get it." However, by implementing multiple precautions, vehicle owners can make it much harder for thieves to succeed.
To protect against fuel theft, it is recommended to combine different methods, such as using a locking fuel cap, parking in secure areas, and installing anti-siphon devices with strong physical protection. These measures can significantly reduce the risk of becoming a victim of fuel theft.
It is worth noting that some anti-siphon devices may not fit all fuel tank necks, so it is important to measure the fuel tank neck size to ensure a proper fit. Additionally, some devices may restrict fueling speed, but they are designed to provide excellent flow rates while ensuring superior access protection. Overall, by staying vigilant and utilizing a combination of the available precautions, vehicle owners can effectively deter fuel thieves and protect their gasoline.

Anti-syphon devices are easy to install
These devices are typically made from high-quality materials, such as metal or PVC pipe, and are guaranteed for the life of the fuel tank they are installed in. They are compatible with a wide range of vehicles, including trucks, buses, and foreign Class 7 trucks, and can be easily fitted into most fuel tank necks.
The installation process for an anti-syphon device is straightforward and can be completed in a few simple steps. It is recommended that the device is installed at least 6 inches higher than any of the sprinkler head valves in the watering system. This ensures that the back-flow prevention mechanism in the valve functions correctly.
To install the device, begin by inserting a piece of metal or PVC pipe with dual threaded ends into the isolation valve. This valve is usually placed directly after the coupling with the main water line in your plumbing system. Then, insert the other threaded end into the metal elbow of the same diameter as the pipe. Be sure to wrap the ends with plumber's Teflon tape before tightening to ensure a secure fit.
If your anti-syphon device did not come with a sprinkler head attached, you will need to install one. To do this, use a three-inch piece of PVC pipe and secure it to the valve and sprinkler head with PVC glue.

Anti-syphon devices are reasonably priced
Anti-syphon devices are an effective solution to prevent fuel theft. They are designed to stop the flow of contaminated water from entering the water supply system. These devices are particularly useful for outdoor faucets where a garden hose may be left on the ground or in water puddles. If there is a sudden drop in water pressure, dirty water can be sucked back into the water pipes through the hose, contaminating the water supply. Anti-syphon devices are also useful for situations where a hose may be left dangling from a faucet, such as in laundry rooms or outdoor garden spigots.
Anti-syphon devices can be an inexpensive solution to protect against fuel theft and contamination. For example, the EZ Truck Store offers anti-syphon devices that are guaranteed for the life of the fuel tank they are installed in. They are easy to install, made from quality materials, and deter even the most determined fuel thieves. With over 800,000 in use, these devices are a popular and reasonably priced option to prevent syphoning.
The price of anti-syphon devices can vary depending on the product size and color. However, there are affordable options available, such as those offered by the EZ Truck Store, which are designed to fit most HD and MD Freightliner, Kenworth, Western Star, Sterling, Volvo, Mack, and International diesel fuel tank necks. These devices are patented snap-in anti-syphons that do not restrict fueling and eliminate splash-back.
Overall, anti-syphon devices offer a cost-effective solution to prevent fuel theft and contamination. They are easy to install, effective, and can be purchased at a reasonable price, making them a popular choice for many individuals and businesses looking to protect their fuel tanks and water supply systems.

Anti-syphon devices are an effective solution to prevent fuel theft
Fuel theft is a common problem, and anti-syphon devices are an effective solution to prevent it. These devices are designed to deter thieves from stealing fuel by making it difficult for them to access the fuel tank. They are easy to install and can be fitted to most fuel tank necks, including those found in trucks, buses, and foreign Class 7 trucks.
Anti-syphon devices work by preventing the insertion of a tube into the fuel tank, which is the most common method used by thieves to siphon fuel. The device creates a barrier that blocks the entry of a tube, while still allowing fuel to flow freely into the tank during refuelling. This simple mechanism effectively prevents theft and protects your fuel.
One example of an anti-syphon device is the stainless steel twist-in fuel fill hole, originally introduced in the 1970s when fuel theft was rampant. This device is twisted into the fuel filler hole, slowing the flow of gas into the tank. While this design is effective, it has also led to thieves drilling holes in the bottom of tanks to drain the fuel.
Modern anti-syphon devices have evolved to address these new tactics, offering enhanced security. Snap-in anti-syphon devices, for instance, are designed to be extremely secure and easy to install. They are made from high-quality materials and are guaranteed for the life of the fuel tank. These devices are also inexpensive, making them a cost-effective solution for preventing fuel theft.
Overall, anti-syphon devices offer a practical and affordable solution to the problem of fuel theft. By installing these devices, vehicle owners can deter thieves and protect their fuel, ensuring their vehicles remain safely fuelled and operational.
