Abstract
A fuel selection device is provided for allowing a user to connect the cylinders of an internal combustion engine to a user-selected fuel source. The fuel selection device includes a housing that defines a cavity for receiving a moveable selector therein. The selector defining first, second, third and fourth flow paths. The first and second flow paths are used for flowing a first type (e.g., natural gas) of fuel from a fuel source to the cylinders of the engine. The second and fourth flow paths are used for flowing a second type of fuel (e.g., liquid propane vapor) from a fuel source to the cylinder. The selector is movable between a first position wherein first and second cylinders communicate with the first and second flow paths, respectively, and a second position wherein the first and second cylinders communicate with the second flow path and fourth flow paths, respectively.
