Abstract
The invention provides a fuel feed system for an internal combustion engine, the system including a fuel pump, a vapor separator including a fuel chamber having an inlet and an outlet and being adapted to contain a supply of fuel, the vapor separator including a float valve and a passage for venting fuel vapor from the chamber when the supply of fuel is below a predetermined level, and a vapor pump communicating with the passage and a source of cyclically varying pressure for pumping fuel vapor from the vapor separator and to a location remote from said source of alternating pressure, the fuel vapor pump operating independently of the fuel pump.
