Fuel system

摘要

A fuel system is described which comprises a high pressure fuel pump (16) arranged to supply fuel under pressure to a plurality of injectors (20). A backleak connection line (36) is arranged to return fuel from the injectors (20) to a fuel reservoir (10). A venturi pump (34) is connected to the backleak connection line (36) and is arranged to draw fuel from the line (36) to reduce the fuel pressure therein.
