Abstract: A fuel inlet device for a fuel tank includes a cap member connected detachably to a fuel inlet port, which includes a tube body. When a plug body of the cap member is inserted into the tube body through an upper central opening defined by an inner annular wall, a notch in the inner annular wall permits a protrusion unit having first and second abutting blocks and formed on the plug body to pass therethrough such that the cap member is rotatable relative to the tube body between an open position, where the second abutting block of the cap member abuts a curved inner wall defining the notch, and a closed position, where the cap member is connected tightly with the fuel inlet port.

Abstract: A radiator cover includes a base seat with a mounting portion. A thermometer includes a temperature-indicating portion disposed within the mounting portion, an externally threaded portion extending downwardly from the temperature-indicating portion and having a bottom surface, and a sensor portion extending downwardly from the bottom surface. A threaded seat includes an internally threaded portion engaging the externally threaded portion, and an annular inner surface disposed below the internally threaded portion and confronting the bottom surface. An annular water seal is disposed between the bottom surface and the annular inner surface of the threaded seat to establish a water-tight seal therebetween.
