Abstract
A secondary fuel pump assembly for a fuel tank in a vehicle includes a reservoir adapted to be disposed in the fuel tank having a top defining an overflow fuel level of the reservoir. The secondary fuel pump assembly also includes a conduit conducting return fuel from an engine of the vehicle to the reservoir and a jet pump having a discharge outlet in the reservoir and an inlet operatively connected to the conduit. The secondary fuel pump assembly includes an overflow fuel member defining a flow path for overflow of fuel in the reservoir and a guide member extending into the overflow fuel member and having at least one aperture extending therethough. The secondary fuel pump assembly further includes a guide disposed over the guide member and movable relative thereto to open and close the at least one aperture and a float connected to the guide to move the guide as a fuel level rises and falls in the reservoir.
