Abstract
A fuel system for a multi-cylinder compression ignition engine includes a tubular body (10) having an internal step (11) against which is located a flanged pump barrel (12), a pair of valve blocks (22, 23) mounted in end to end relationship between the barrel (12) and a mounting block (24) secured to the body by bolts (25) which provide a clamping force which ensures a liquid tight seal between the engaging end faces of the blocks and the barrel. A bore (14) in the barrel (12) houses a pumping plunger (15) and the valve blocks house a delivery valve (41) and a spill valve (26), respectively. The spill valve is controlled by an electromagnetic valve (30) mounted on the mounting block.
