What Do We Provide to Businesses as
Fuel Guard by Protecting Fuel Tanks in Trucks and Tractor Units?

Fuel Guard Prevents 100% Fuel Abuse in Trucks and Tractor Units
Fuel Guard provides physical protection for all critical points such as the fuel tank neck, float, fuel filter, and drain plug. It strictly prevents theft methods such as siphoning with a hose, drilling, and dismantling before the incident occurs.

Fuel Guard Ensures Operational Efficiency and Continuity
Fuel depletion due to theft leads to vehicles being stranded on the road, delivery delays, and customer dissatisfaction. Fuel Guard reduces these disruptions to zero. By ensuring your vehicles operate as planned without interruption, it maximizes operational efficiency and prevents business loss.

Fuel Guard Provides Rapid Return on Investment (ROI) to Businesses
The Fuel Guard system is an investment rather than a cost. Even a single prevented fuel theft or repair expense can cover the investment cost of the system in a short time. By preventing all costs associated with theft, malfunction, operational delays, and premium increases, it provides a fast and clear Return on Investment (ROI) to the business.

Fuel Guard Reduces Driver Stress and Increases Personnel Motivation
Drivers are under constant stress with the fear of fuel theft when they park their vehicles. Fuel Guard systems allow drivers to know their fuel is safe. This situation enables drivers to focus on their work, reducing their stress and thereby increasing overall personnel motivation and loyalty.

What Problems Can You Experience
If You Do Not Use Fuel Guard Fuel Tank Protection Systems?

Risk of Fuel Theft
The absence of physical protection barriers like Fuel Guard leaves the fuel tank defenseless against thieves.

Operational Disruption and Downtime
A single theft incident caused by the lack of Fuel Guard can trigger a series of technical issues, ranging from fuel filter clogging to fuel pump failure, creating continuous repair costs.

Decrease in Labor and Performance Morale
Disruptions caused by the lack of Fuel Guard protection lower the motivation of drivers and operators, reduce labor productivity, and create a crisis of confidence within the business.
Which Areas of Trucks and Tractor
Units Do We Protect as Fuel Guard?
Tank Cap and Tank Neck (Anti-Siphon Protection)
Intervention through the tank cap is the most common and first method that comes to mind in fuel theft. Since truck and tractor tanks have large volumes, it is common to encounter forced open, broken caps, or caps opened with a copied key.
Fuel Guard protects this main entry point with high-security, patented locking systems and physical shields that show extraordinary resistance against external interventions (master keys, levers, etc.).
However, Fuel Guard protection does not end here; the real deterrence begins inside the tank neck. "Anti-Siphon" (or "Siphon Preventer") technology comes into play at this point. This special apparatus, permanently mounted to the tank neck, makes it physically impossible to insert a hose, pipe, or similar device into the tank and withdraw fuel by "siphoning."
Even if the tank cap is opened in some way, the anti-siphon filter prevents the thief from reaching the fuel. This is Fuel Guard's first and strongest line of defense.
Fuel Float
Experienced thieves, upon realizing the tank cap is secure, search for alternative and weaker points. In truck and tractor tanks, this weak link is usually the fuel float area. This sensitive part, which measures the vehicle's fuel level, is typically located on the top of the tank in a relatively less protected area and can be easily accessed by removing a few screws.
Thieves can gain direct access to the tank or siphon fuel quickly by removing or breaking the float from its seat. Moreover, this intervention causes the float to malfunction, resulting in high repair costs for the fleet owner in addition to the cost of the theft itself.
Fuel Guard, anticipating this critical vulnerability, offers specially designed steel protection covers and locking systems for the float area. This high-security cover is mounted over the float, completely closing this upper area of the tank against external interventions. Thus, even if the tank cap is secure, theft attempts that could be made through the float also result in failure.
Under-Tank Fuel Drain Plug
One of the methods often overlooked in fuel security but with the most devastating consequences is draining the tank from underneath. Under every fuel tank, there is a drain plug placed for maintenance and cleaning purposes.
Professional thieves, especially during overnight stays or in unsecured parking areas, get under the vehicle, unscrew this standard plug, and ensure the entire tank is emptied in a short time. This method is one of the hardest to notice and where the most fuel is stolen.
Fuel Guard has developed special security solutions for tank drain plugs to eliminate this extremely serious risk. These solutions include locked plugs that replace the standard plug and are equipped with special keys, codes, or designs that make external intervention impossible.
Some Fuel Guard models completely block access to this area by placing an additional protective cover over the plug. Thanks to this, the risk of "bottom draining" is reduced to zero, and the fuel tank is put under 360-degree protection.
Frequently Asked Questions
in the Field of Fuel Tank Security for Trucks and Tractor Units
Does the Fuel Guard Anti-Siphon system slow down the fuel filling speed?
No. Fuel Guard Anti-Siphon devices are designed for high flow rates in accordance with international standards. It absolutely does not affect the filling time and speed even with high-flow fuel pumps used in trucks and tractor units, maintaining the operational efficiency of your fleet.
Which truck and tractor unit brands is Fuel Guard compatible with?
Fuel Guard solutions provide full compatibility with the standard fuel tank necks and float designs of all major European and American truck and tractor unit brands such as Mercedes-Benz, MAN, Ford Trucks, Scania, Volvo, DAF, and Renault. A security solution is offered for a wide range of vehicles regardless of the model.
Is it not enough to just protect the tank cap? Why does Fuel Guard protect three points?
A locked cap alone does not prevent siphoning theft, which is the most common method. Fuel Guard provides complete security by simultaneously protecting the three main targets of thieves: The Tank Neck (Siphoning), The Float Area (Dismantling), and The Drain Plug (Emptying). Even if one point is bypassed, other points continue to protect the fuel.
Does Fuel Guard installation affect the vehicle warranty or damage the tank?
No. Fuel Guard products do not require any permanent cutting, drilling, welding, or modification on the original fuel tank of the vehicle. Since installations are performed using simple screwing or seating principles at existing connection points like the tank neck or float cover, they do not damage the vehicle warranty or the physical integrity of the tank.
