Fuel injection device comprises a housing (30), a recess (36) formed in the housing, a valve element (38) arranged in the recess, a sleeve (62) surrounding the end section (58) of the valve element in a fluid-tight manner, and a hydraulic control arm (82). A section (34) of the housing has a spring section (70) which can be plastically deformed by the sleeve. An Independent claim is also included for a fuel system containing the fuel injection device. Preferred Features: The spring section comprises a spring ring with its outer edge deformed on the section (34) of the housing. The spring ring is formed as a thin-walled metal membrane.
