This patent describes an electromagnetically actuated fuel pump for a diesel engine fuel injection. It comprises a body adapted to receive fuel from a source; a rotatable camshaft supported in the body so as to be rotatable about an axis, and having a pair of cam lobes including a first cam lobe and a second cam lobe adapted to rotate in an annular path about the axis of rotation of the camshaft; at least one pair of reciprocating pumping elements mounted in the body perpendicular to the axis of rotation of the camshaft, each of the pumping elements including an elongated plunger having an axial passage including a first end and a second end; and means for fluidly connecting the pumping elements to fuel injection means for passing fuel under pressure thereto in response to rotation of the camshaft.
