Fuel supply systems incorporating fuel pump assemblies having vents leading from upper portions of filter cases to vapor phase portions of a fuel tank. In one embodiment, a fuel pump is located wholly within a filter case with a relief port also provided within the case. Location of the components and baffles as well as a vapor vent promote flow of entrained vapor in the fuel away from the pump intake. Further, with the present arrangement, vapor is less likely to be formed.
