The invention claimed is: 1. A fuel injection system for an internal combustion engine, the system comprising a high-pressure pump, a plurality of injectors, and a plurality of pressure reservoirs equal in number to the number of injectors for supplying fuel from the high-pressure pump to the injectors, a different one of the plurality of pressure reservoirs being disposed between the high-pressure pump and each of the plurality of injectors, each pressure reservoir having at least one first high-pressure connection, at least one second high-pressure connection and one branch for an injector, means for connecting the plurality of pressure reservoirs in series, a fuel filter in each pressure reservoir, one filter bore provided in each pressure reservoir for receiving the fuel filter, and wherein each fuel filter is embodied as a rod filter or as a screen filter. 2. The fuel injection system as defined by claim 1, further comprising a fuel-filled reservoir volume in each pressure reservoir. 3. The fuel injection system as defined by claim 2, wherein the reservoir volume and an elasticity of the pressure reservoir are adapted to the associated injector. 4. The fuel injection system as defined by claim 1, wherein each of the pressure reservoirs is produced by forging or casting. 5. The fuel injection system as defined by claim 2, wherein each of the pressure reservoirs is produced by forging or casting. 6. The fuel injection system as defined by claim 1, wherein at least one of the first high-pressure connection, the second high-pressure connection and the branch is welded to the reservoir volume. 7. The fuel injection system as defined by claim 2, wherein at least one of the first high-pressure connection, the second high-pressure connection and the branch is welded to the reservoir volume. 8. The fuel injection system as defined by claim 1, wherein at least one of the first high-pressure connection, the second high-pressure connection and the branch is screwed to the reservoir volume. 9. The fuel injection system as defined by claim 2, wherein at least one of the first high-pressure connection, the second high-pressure connection and the branch is screwed to the reservoir volume.
