A fuel pressure regulator includes a fuel inlet; a fuel outlet; a seating surface; and a valve member assembly. The valve member assembly includes a poppet and also includes a sealing member which is centered about a valve member assembly axis, is annular in shape, and includes a sealing member surface. The valve member assembly is moveable between 1) a closed position in which the sealing member surface annularly engages the seating surface, thereby preventing fuel flow from the fuel inlet to the fuel outlet and 2) an open position in which at least a portion of the sealing member surface is spaced apart from the seating surface, thereby allowing fuel flow from the fuel inlet to the fuel outlet. A spring biases the valve member assembly toward the closed position and is centered about a spring axis which is laterally offset relative to the valve member assembly axis.

Fuel pressure regulator

A fuel pump includes a housing which is tubular; an inlet plate closes one end of the housing and an end cap closes the other end of the housing. The end cap includes an outlet passage and a vapor purge passage. An electric motor within the housing rotates a pumping element to pump fuel through the fuel pump. A valve assembly of the fuel pump includes a valve member located within the purge passage, the valve member being moveable between a first position which blocks fluid communication therethrough and a second position which provides fluid communication therethrough. A valve retainer fixed to the end cap includes a first leg, a second leg which is opposed to the first leg, and a cross-beam which joins the first leg and the second leg. The valve member is stopped by the cross-beam at the second position.
