Anti-siphon valves
Capless fuel tanks are designed to prevent fuel siphoning due to the presence of rollover valves. These valves contain a ball in the filler neck that blocks the insertion of a hose into the gas tank. However, this does not prevent someone from tampering with the fuel system by pouring something into the tank.
To address this concern, some individuals opt for a locking fuel filler cap, which can be purchased as an aftermarket product. While this may deter theft, it is important to note that a determined thief could still drill a hole in the plastic tank to access the fuel.
Another option to enhance security is to install an anti-siphon valve. These valves are designed to prevent the accidental or unauthorised siphoning of fuel from a tank. They are available for both aboveground and below-ground fuel storage tanks and can provide an additional layer of protection against fuel theft.
Some vehicles may already have anti-siphon valves installed from the factory, but it is always a good idea to check with the manufacturer or a trusted mechanic to confirm the presence of such features. Additionally, it is worth considering the overall security of your vehicle and taking precautions such as parking in a locked garage or well-lit, monitored areas when possible.
While anti-siphon valves and locking fuel caps can act as deterrents, it is important to acknowledge that determined fuel thieves may still find ways to access the fuel. As such, a comprehensive approach to vehicle security, including a combination of mechanical and technological solutions, is always recommended.

Fuel cap locks
Capless fuel tanks are a relatively modern innovation that is becoming more common with the latest model vehicles. They have several advantages, including making it easier to fill your tank, reducing fuel theft, and preventing vandalism by making it harder for someone to place something harmful in your tank. However, some people are concerned about the lack of a locking mechanism on capless fuel tanks, especially with the rise in fuel theft and vandalism.
While some vehicles with capless fuel tanks may have an anti-siphon valve installed from the factory, others may not. This has led to concerns about the potential for fuel theft, as thieves could punch or drill a hole in the plastic tank to steal the fuel. Additionally, there are worries that without a lock, someone could easily dump something harmful into the tank.
To address these concerns, some people have considered installing a locking fuel cap or a lock on the fuel door. However, opinions vary on the effectiveness of these measures. Some believe that a locking fuel cap could deter thieves and vandals, even if it doesn't completely prevent fuel theft. On the other hand, others argue that a lock will only keep honest people honest, and determined thieves could still find ways to access the fuel. There are also concerns that installing an aftermarket lock could cause more damage to the vehicle if someone attempts to pry it open.
Some vehicle manufacturers, such as GM, offer a universal cap for their capless gas tanks, which is inexpensive and easy to fit. This cap can be placed on most GM vehicles, except for the Corvette. However, it's important to note that even with a locking cap, determined individuals could still cut the filler hose or drill the tank to access the fuel.
Overall, while there are options for adding a lock to a capless fuel tank, it's important to weigh the benefits against the potential drawbacks. Capless fuel tanks have their own built-in security measures, and the decision to install additional locks should be made based on individual needs and circumstances.
