A method for monitoring a fuel supply system in an internal combustion engine includes the steps of: recording a first pressure value in the fuel supply system in a region of the fuel supply system associated with a pre-filter and upstream of a low pressure pump; recording a second pressure value in the fuel supply system downstream of the low pressure pump in a region of the fuel supply system associated with a primary filter; monitoring the first pressure value and the second pressure value for an error state of the fuel supply system; and recognizing the error state only if the error state is plausible on a basis of both the first pressure value and the second pressure value.

Method for monitoring a fuel supply system of an internal combustion engine and internal combustion engine for carrying out such a method

A distributor apparatus of a common rail system for an internal combustion engine. The distributor apparatus is designed with at least one distributor device having a high-pressure line for fuel and a plurality of feed lines branching off from the high-pressure line within the distributor device. Each feed line leads to an individual accumulator and an injector. The feed line is associated with a restriction device and a discharge bore, which is designed to cooperate with a pressure-measuring device and which is arranged downstream of the restriction device, such that the restriction device is arranged in the feed line and the discharge bore, arranged in the distributor device, is connected to the feed line downstream of the restriction device.
