Abstract In a marine fuel system for a fuel injected internal combustion engine, a fitting is provided in the vapor supply line . The fitting has a first reduced diameter passage providing a vacuum bleed orifice passage partially venting vacuum from the induction manifold . to atmosphere, to limit peak vacuum applied to the vapor separator from the induction manifold . The fitting has a second reduced diameter passage providing a flow restrictor passage limiting the volume of flow of fuel vapor from the vapor separator to the induction manifold . The fitting limits fuel vapor supplied from the vapor separator to the induction manifold at peak vacuum from the induction manifold during rapid engine deceleration to prevent an overly rich fuel air mixture in the induction manifold otherwise causing rough idling or stalling. The fitting also solves hot restart problems. Another modification is provided by a one- way check valve permitting only one-way flow of fuel from the vapor separator to the high pressure fuel injection pump
