The pump head comprises a head housing including a body portion (24), and a turret portion (30) extending from the body portion (24), a pumping chamber (36) defined within the body portion (24), a pumping element bore (34) for receiving a pumping element (32) in use, the pumping element bore (34) extending from the pumping chamber (36) and through the turret portion (30), and a leakage return passage (74). The pump head (14) further comprises a sleeve (70) arranged around the turret portion (70) to define a leakage flow path (72) to allow fuel flow from the pumping element bore (34) to the leakage return passage (74). The pump head is suitable for use in a fuel pump of the type in which a cam drive arrangement of the pump is lubricated by engine oil, since contamination of the engine oil with fuel can be minimised.",
