Abstract: A magnetic fuel tank cap is provided for closing off the filling inlet tube of a motor vehicle which consists of an externally threaded cylindrical shank, which threadably engages with the filling inlet tube of the motor vehicle. A head is secured to the shank and is larger than the shank. When the head is turned to drive the shank into the filling inlet tube, the head will seal the filling inlet tube. A magnet is on top of the head for releasably connecting the head, when inverted, to a metallic part of the motor vehicle after the shank is removed from the filling inlet tube. In other embodiments adaptors are provided to releasably connect the head of a conventional fuel tank cap to the metallic part of the motor vehicle.
