Abstract: An anti-fuel theft device for a fuel tank is disclosed. The device has a body member that has a channel that covers the filler tube and cap assembly of the fuel tank, a ring member coupled to a top portion of the body member, a lid assembly coupled to and forming a cover over a top portion of the ring member, a hinging mechanism coupled to the ring member and to the lid assembly for pivoting the lid assembly over the ring member, and a locking mechanism coupled to the lid assembly. Flanges on the lid members may form a collar over the lip member to prevent a person from prying the lid members off of the device. The device may also have a guard device to prevent tampering of a locking device that may be used to lock the lid assembly.
