A high-pressure fuel pump includes a pump housing and a cover element. The cover element is connected to the pump housing and has a wall. A damping volume is arranged between the cover element and the pump housing. The wall has a reinforcement, which is formed such that a resonant frequency of the cover element lies above 9 kHz, preferably above 11 Hz, in particular above 12 kHz.
