  • the conduit comprises a cylinder injector pipe. More preferably, the conduit further comprises a manifold communicable with the cylinder injector pipe. Most preferably, the manifold comprises a cylinder injector pipe fitting, a cylinder return pipe fitting, a stove return pipe fitting and a radiator return pipe fitting.
