Abstract

A device that is placed over an inlet of a motorcycle gas tank that prevents the overflow of gasoline during the filling of the motorcycle gas tank. The device comprises an upper portion that accepts a gas pump nozzle, an inner core that captures gasoline fumes and provides for pressure build up inside the gas tank, and a lower portion that is designed to mesh with the motorcycle gas tank opening. The upper portion and inner core are basically the same on each model of the device, or motorcycle cuff. The lower portion of the motorcycle cuff is specifically designed to adapt to different types of motorcycle gas tanks, such as flush mounted and indented gas tank openings. The motorcycle cuff gives motorcycle riders the same gas filling advantages of filling their tanks to a desired full level, as those enjoyed by car drivers, by working in conjunction with the automatic shut-off feature available in most gasoline pumps.

Dependent claims

An apparatus comprising a circular cuff that is temporarily placed on top of an opening of a motorcycle gas tank or over a metal nozzle of a standard gasoline pump, during a filling of the gas tank, after the nozzle is through the cuff the user can visually verify a distance the nozzle protrudes out of an opposite end of the cuff, the apparatus provides pressure against a corrugated rubber hose that surrounds the metal nozzle, the apparatus further prevents under-filling of the gas tank by averting an automatic shut-off feature of the gasoline pump until the gas tank is actually full, the circular cuff comprising:

a top portion that accepts the metal nozzle but blocks passage of the corrugated rubber hose;
an outer wall that provides structural support to the cuff, wherein a circumference of the outer wall is greater than a circumference of the rubber hose and of the opening to the gas tank;
an inner core that allows passage of the metal nozzle through the apparatus;
and,
a lower portion that forms a temporary seal with the opening of the gas tank;
wherein, the circular cuff prevents gasoline fumes from escaping out of the gas tank and into the atmosphere, provides a sufficiently low build up of pressure inside the motorcycle gas tank so that the automatic shut-off feature of the gasoline pump is prevented from activating until the motorcycle gas tank is actually full, but also ensures the automatic shut-off feature is activated before gasoline overflows out of the motorcycle gas tank.
