An improved safety plug device for internal combustion engine fluid fuel lines, is described comprising, in combination: a. a plug body kit having separate and independent first and second fuel line plugging portions. The first portion comprising a solid core having means for plugging insertion into fuel lines of various internal bore diameters comprising a multiple stepped outer surface. The second portion comprising an outer sheath with a central cavity in which the core is stored and releasably removed therefrom. The cavity is defined by multi-stepped inner surfaces of the sheath mating with the multiple stepped outer surface of the core. The sheath has an open end and a closed end and means to internally receive and plug fuel lines of various outer diameters in the cavity through the open end by virtue of the multi-stepped inner surfaces when the core is out of the sheath.
