发明名称 Fuel inlet repair device
摘要 A fuel inlet repair device for repairing the damaged threaded fuel inlet opening of an engine carburetor or fuel injection pump to allow the fuel inlet line to be connected to the fuel inlet opening. The fuel inlet repair device according to the present invention consists of a generally tubular shaped outer plug or member formed of a plastic material impervious to fuel and having an outer diameter corresponding generally to the size of the opening of the fuel inlet passage in the carburetor or fuel injector pump. The tubular shaped member has a tapered opening passing longitudinally therethrough, with threads formed along the tapered bore or opening. An inner plug having threads on the outer surface thereof corresponding to the tapered threads on the inner opening or passage through the outer tubular plug is designed to be inserted into the threaded opening. The inner threaded plug member also has an opening longitudinally therethrough, with one end of said opening being formed in a hexagon shape or a shape generally corresponding to an installation tool for threading the inner plug into the threaded opening in the outer tubular shaped plug member. The outer tubular shaped plug member is inserted into the carburetor fuel inlet opening and the inner plug is then threaded into the threads in the tapered threaded bore through the outer plug. As the inner plug is threaded further into the tapered bore in the outer plug, the outer surface of the outer plug is caused to expand into engagement with the damaged threads and inner surface in the carburetor fuel inlet opening in such a manner as to seal the space between the outer surface of the outer plug and the inner bore of the carburetor fuel inlet opening. The fuel inlet line is then connected to the threads in the bore in the outer plug, resulting in a sealed connection between the fuel inlet line and the carburetor fuel inlet opening.
