Abstract
A fuel tank assembly for a motorcycle includes a main tank and an auxiliary tank joined by a fuel hose or pipe. A breather pipe having an inlet in an upper portion of the auxiliary tank extends to a position proximate the fuel inlet of the main tank to exhaust air from the auxiliary tank to increase its effective capacity. The breather may extend either separately from or within the fuel pipe and may be provided either internally or partially externally of the main tank; the auxiliary tank may be provided with a pump operable when a low fuel level is reached in the main tank, which increases the freedom of placement of the auxiliary tank relative to the carburetor.
