Abstract:
An auxiliary fuel tank mounts on top of a primary fuel tank to provide additional fuel capacity. The auxiliary fuel tank and primary fuel tank establish a single fuel volume. The auxiliary fuel tank contains interconnecting means to replace the primary tank gas cap, support auxiliary fuel tank, and can detachably attach the auxiliary tank to the primary tank at the fill point of the primary tank. The bottom of the auxiliary fuel tank is equipped with a cap replacement for the primary tank and interconnects to form a seal. The interconnection includes an inlet tube that protrudes in and through the primary tank fill point to provide for the flow of gasoline and including ear members to prevent liquid from passing back into the auxiliary fuel tank. The auxiliary fuel tank includes a separate fill point to allow for fueling of the system once attached. The auxiliary fuel tank can be shaped complementary to the primary tank outer surface and may be fastened to the primary tank or motorcycle frame. The invention also provides a method of providing additional fuel capacity with an auxiliary fuel tank and attaching it to the primary tank directly to the primary tank fill point.
