Abstract: A pump assembly (30) for use in an internal combustion engine comprises a pump housing (32a, 32b) provided with a bore (34) within which a pumping plunger (36) is reciprocal along a plunger axis; and a pump chamber (38) defined at one end of the bore (34) within which fuel is pressurised to a relatively high level as the pumping plunger (36) reciprocates within the bore (34), in use. A clamp member (46) applies a clamping load to the pump housing (32a, 32b), having at least a component that is aligned with the plunger axis, through a surface of the pump housing located approximately axially above the bore (34). This has the effect of generating a compressive stress in the pump housing in close proximity to the plunger bore (34) to counter tensile stress within the pump housing due to pressurised fuel within the pump chamber (38).
