A fuel pump is provided for pressurising fuel in a high-pressure fuel injection system. The fuel pump comprises a pump head, a pumping element, a frame and a casing. The pump head has a pumping chamber that is arranged to receive fuel to be pressurised. The pumping element is arranged to reciprocate responsive to movement of a driving element, the pumping element defining, in part, the pumping chamber so that, in use, as the pumping element reciprocates, a force, transferred from the driving element, is applied to the fuel within the pumping chamber to pressurise the fuel. The frame is arranged to support the driving element and the pump head. The casing defines an internal volume for containing fluid, wherein at least a part of the frame, at least a part of the drive element, and at least a part of the pumping element are received in the casing. |
