Abstract
A filler device which can be mounted in the fuel tank of a motorcycle to enable complete filling of the tank, when a fuel dispenser is utilized which has a vapor recovery seal that must be pressed against the outside of the tank so that the fuel nozzle must project several inches into the tank. The filler device includes walls forming a chamber with an open upper end for receiving the fuel-dispensing nozzle, an open lower end for flowing the fuel into the tank, and a seal assembly which can seal to the end of the nozzle to prevent fuel from entering the chamber and activating the shut off sensor on the nozzle when the tank is partially filled. When the tank is substantially full, fuel can flow through a drain opening near the top of the chamber to fill it and activate the nozzle shut off sensor. When the nozzle is withdrawn from the tank, the seal retracts to a location near the top of the tank, to permit substantially complete filling, or 'topping out' of a more than half-full tank.
