Beyond Anti-Siphon Valves
Traditional anti-siphon valves sit inside the fuel filler neck and attempt to block siphoning hoses. But they can be defeated with slim tubing, and they do nothing to prevent fuel contamination. The Military Fuel Vault takes a completely different approach — it covers and locks the entire fuel filler area, making it impossible to insert anything into the tank.
Beyond Locking Gas Caps
Locking gas caps are the most common fuel theft deterrent, but they are the least effective. They can be pried off with a screwdriver, broken with pliers, or simply cut off. Even when intact, they leave the fuel filler neck exposed. The Military Fuel Vault eliminates all of these vulnerabilities.
Complete Fuel System Security
The Military Fuel Vault does not just make siphoning difficult — it makes it physically impossible. The keyed locking door covers the entire fuel filler area with a tamper-resistant enclosure. There is no gap for a hose, no opening for a funnel, no access point for any tool. Your fuel system is completely sealed.
