ABSTRACT:
A fuel treatment apparatus having a settling chamber with a fuel introducing conduit passing through the top of the chamber and extending to a lower portion of the chamber to define a fuel inlet in the lower portion of the chamber. A buoyant valve means is located within the first conduit means to permit fuel introduction during normal operation but to close off the conduit during periods of non-operation and thus closing off fluid communication between the fuel treatment apparatus and the fuel tank. A fuel outlet is provided to remove the fuel after the treatment. A recess in the bottom of the chamber has drain means in the bottom thereof for the removal of moisture from the bottom of the chamber. Novel means are provided to permit introduction of fuel when the normal fuel inlet is clogged, for example, by the freezing of collected moisture therein. This is provided by means of a secondary small fuel inlet in an upper portion of the first conduit means.
