The fuel injection pump (30) includes a pump drive shaft (36) which rotates at a speed proportional to engine speed and drives a gerotor supply pump assembly (46). The pump drive shaft is disposed in a bore of the pump housing (34). Pressurised fuel from an outlet channel (66) passes through a passage (70) into a cylinder (72) of a piston-cylinder assembly in the lower part of the housing (34). The pump (46) supplies a fuel gallery (74) itself connected with the outlet channel (66). The fuel injection pump has opposed fuel pumping pistons (112) housed within a rotor (94) which is associated with fuel distribution, metering and timing controls.
