Abstract: A fuel pump module includes a fuel pump, a housing, a filter, a bracket, a lid, a fuel passage, and a pressure regulating valve. The fuel pump supplies a fuel in a fuel tank that defines an opening to an outside of the fuel tank. The housing has a cylindrical shape and supports the fuel pump. The bracket connects the filter to the housing. The lid covers the opening and defines a discharge port through which the fuel is supplied to the outside. The fuel passage connects the fuel pump to the discharge port. The pressure regulating valve has a gravity center inside a space defined by a first virtual cylindrical surface including the housing. A minimum circumscribed circle of both the housing and the filter is smaller than the opening.

Abstract: A fuel pump module includes: a pump unit; a lid provided to close an opening of a fuel tank; and a flexible fuel tube. The pump unit includes a fuel pump configured to pump fuel out of the fuel tank, a housing that holds the fuel pump, and a filter configured to filter the fuel. The lid has a discharge port to supply the fuel to outside of the fuel tank. The flexible fuel tube connects the pump unit and the discharge port. The housing includes a guide portion configured to fix the pump unit to a fixing member having a pair of rails provided in the fuel tank, and a separation regulating member configured to regulate the guide portion from separating from the pair of rails by engaging with the fixing member.

Abstract: A housing has an inner passage to communicate with both a fuel passage, which is to conduct fuel from a fuel pump, and a return passage, which is to return fuel a fuel tank. A valve body is movable in the housing to change a minimum flow passage cross-sectional area of the inner passage. A spring is connected to the valve body and changes its biasing load in correspondence with a fuel temperature to move the valve body. The spring moves the valve body such that the minimum flow passage cross-sectional area, when the fuel temperature is equal to or higher than a predetermined vapor generation temperature, is larger than the minimum flow passage cross-sectional area when the fuel temperature is lower than the vapor generation temperature.
