The invention relates to a pump unit arranged in an inner tank () of a fuel tank, comprising a fuel pump () which is used to pump fuel to the internal combustion engine of a motor vehicle; an ejector pump () which is connected to the fuel pump () and used to pump fuel out of the fuel tank into the inner tank (); and at least one filter element () which is used to filter fuel, wherein a housing part which is connected to the fuel pump () is provided with at least one channel () for guiding said fuel. In order to simplify the structure of the pump unit () and to enable substantial pre-assembly, the housing part () is configured in such a way that it can hold the at least one filter element (), and the channel () is exclusively guided inside the housing part () from the ejector pump () and/or the fuel pump () to the filter element ().
