Abstract
A liquid level sight gauge useful in the fuel tank of a recreational vehicle such as a snowmobile is molded in two parts and can be installed without special tools in simple cylindrical holes provided in the wall of the tank or container. The gauge has a tubular body communicating with projecting cylindrical spigots which are passed through sleeves of a resilient gasket which sleeves secure them in the holes of the container wall.
