Abstract
A vapor separator in an outboard machine which can continuously inject an accurate and stable fuel toward an intake pipe without drawing bubbles discharged from a pump chamber in a high pressure fuel pump and bubbles within the vapor separator by the high pressure fuel pump. The separator is structured such that a filter (2) is arranged in a bottom portion (1A) of a fuel pump receiving case (1), an upstream chamber (10) of the filter (2) is connected to a vapor separator (V) via a fuel inflow passage (1C), a fuel inflow passage (PA) of a high pressure fuel pump (PH) received and arranged within the fuel pump receiving case (1) is connected to a downstream chamber (5) of the filter (2). A vapor discharge chamber (9) is formed so as to face to a bottom portion (PF) of the high pressure fuel pump (PH).
