Abstract
The present subject matter describes a fuel injection system (50), in particular a common-rail injection system, having at least two injectors (64) each comprising a return port, and connected to each other by means of a hose (10) at the return ports. The hose (10) includes an inner cavity (12) in which liquid fuel can flow and is surrounded by a wall (13). The wall (13) is resiliently deformable in such a manner that it damps the hydraulic pulsations of the liquid fuel through a change in volume of the cavity (12), and the hose (10) has a coiled thread insert (18) having a slope angle (a) ranging from 15° - 40°, particularly from 25° - 30°.
