  • In-tank fuel supply apparatus
    Patent number: 6520163
    Abstract: A fuel supply apparatus for installation in a fuel tank includes a fuel pump, a housing, and a filter element disposed in the housing and having an upstream side communicating with the discharge port of the fuel pump. A check valve communicates with a downstream side of the fuel filter, and a pressure regulator communicates with the upstream side of the filter element. A sedimentation flow path may be provided for removing sediment from fuel discharged from the pressure regulator. The sedimentation flow path may be substantially cylindrical vortex spaces between fins disposed on the inner periphery of the pump holder and has blind holes at the bottom for trapping the sediments.
