Abstract
A fuel cap assembly for use on fuel tanks on large vehicles such as straight trucks and buses for reducing and preventing fuel fumes and spills from reaching outside of the fuel tank during fuel filling operations. The cap assembly has interior facing threads that wrap about exterior facing threads on the fuel receiving receptacles on the fuel tanks. The cap assembly includes a lid having a normally biased closed door that only opens when a fuel nozzle is pressed into the door. The cap assembly can be elongated to allow for an interior chamber that allows for an extra catch to stop fuel from reaching outside the tank during the filling of the fuel tank. An O-ring type seal also helps lockably seal the cap assembly to the fuel tank receptacle.
