Abstract

A high-pressure fuel system including a housing having first and second high-pressure bodies (3, 5), which contact one another at a contact face. A high-pressure chamber in the housing passes through the contact face, and at least intermittently a high fuel pressure is present in the chamber (23). A wall part having a longitudinal axis surrounds the housing at least in the region of the contact face, so that a leak fuel chamber (32) is formed between the wall part and the housing which chamber is sealed off from the outside.
