Abstract:
A vapor separator for a fuel pump assembly of an internal combustion engine comprises:a first cap defining a vapor outlet passage and a second cap spaced from the first cap; an elongated heat conductive sleeve disposed between the first cap and second cap and defining a fuel chamber at least selectively communicated with the vapor outlet passage; a float valve device carried by the first cap, disposed within the fuel chamber and constructed and arranged to close and open the vapor outlet passage with rising and lowering fuel levels within the fuel chamber; a housing surrounding and spaced laterally outward from the sleeve; an elongated baffle extended laterally between the housing and the sleeve; a coolant channel defined longitudinally by the baffle and carried between the housing and the sleeve, the coolant channel being segregated from the fuel chamber and having a first end and an opposite second end; a coolant inlet passage communicating with the first end of the coolant channel; and a coolant outlet passage communicating with the second end of the coolant channel.
