Abstract
A system for venting vapors from a fuel tank of an engine, an engine with such a system, and related methods are disclosed. In one embodiment, such a system includes a coupling device having first, second, and third ports that are connected at a junction, where the first and second ports are respectively configured to be at least indirectly coupled to the tank and a carburetor, respectively, and where the third port is in communication with an outside environment via a filter. The system further includes an obstruction that is formed at a location downstream of the junction en route toward the carburetor, the location being either within the coupling device or at a position downstream of that device, such that at least some of the vapors can proceed from the tank to the carburetor and at least some air from the environment is able to proceed toward the tank.
