Abstract
A fuel delivery assembly for directing fuel into an intake manifold of an internal combustion engine includes a fuel tube having an aperture through a sidewall and a flapper pivotably secured to an interior of the sidewall adjacent to the aperture. The flapper is configured to pivot between an open and closed configuration. The flapper pivots to the closed configuration when fuel is provided through the fuel delivery assembly and pivots to the open configuration to allow air to pass through the aperture to flush residual fuel from the fuel tube and into the combustion chamber.
