Abstract
The fuel injection system has a high-pressure pump, by which fuel is pumped at high pressure into a reservoir. By means of a feed pump, fuel is pumped from a fuel tank to the high-pressure pump. By means of a fuel metering device, disposed between the feed pump and the high-pressure pump, the inflow of fuel to the high-pressure pump is adjusted. From the connection between the feed pump and the fuel metering device, a bypass connection leads away to a relief region. An inflow of fuel from the feed pump to the fuel metering device and/or to the bypass connection is effected through at least one conduit in a housing part, and in the at least one conduit, at least one fuel filter is disposed upstream of the fuel metering device and/or of the bypass connection.
