Abstract: A fuel delivery system for a combustion engine has a fuel tank which defines an access hole preferably communicating through either the top wall or bottom wall of the tank. An associated top or bottom flange, both having a fuel channel for flowing fuel out of the tank, sealably covers the access hole. A fuel pump module is located in the fuel chamber of the tank and has a universal, structural, pod which engages either the top or bottom flange while preferably maintaining an axial upright position. The pod defines an axially extending first bore for housing a fuel pump and preferably an electric pump motor and a second bore defined by a cylindrical inner face and spaced radially outward from the first chamber for housing a reversible filter cartridge of the module. The pod also has a fuel discharge nozzle which generally defines a counter bore that communicates axially with the second bore.

Abstract: A low cost bypass pressure regulator preferably for a returnless fuel system supplying liquid fuel to a fuel injector of the combustion engine. The pressure regulator preferably has a valve head disposed at least in part in a valve chamber defined by a circumferentially continuous inner surface carried by a valve body and which transitions radially outward with respect to a center axis and in a downstream direction. The valve head preferably tapers radially inward from a downstream peripheral outer edge of the head. In a closed position, the valve head engages a seat carried by the body with the peripheral outer edge downstream of the seat and radially spaced from and fitted closely to the valve chamber continuous inner surface thus defining a close fit region therebetween. As the valve head opens, the flow cross-section enlarges which reduces or eliminates oscillation of the valve head.
