ABSTRACT:
The safety plug device is adapted to releasably plug the fluid fuel line of an internal combustion engine. The device has an external multiple stepped cylindrical configuration and/or central cavity with a like configuration so that it can be used effectively with various diameters of fuel lines and can either be inserted in the central opening of the fuel line or can be disposed over the fuel line, to prevent loss of fuel after the fuel line is removed from, for example, a carburator. The device is preferably of resilient elastomeric material resistant to deterioration by fuel and can include metal inserts, or be all metal, ceramic, etc. Thus, danger of fire from spilled fuel such as gasoline, kerosene, oil and the like can be readily avoided by the use of the plug device. Moreover, because the plug device physically reinforces the fuel line, clamping of the fuel line at the plug device does not damage the fuel line, in contrast to conventional clamping which breaks down the fuel line. In one embodiment, the plug device includes an outer protective resilient sheath which enables clamps of a single diameter to be effectively used. The device is simple, durable and inexpensive.
