In a fuel delivery device for a motor vehicle a delivery pump (15) is provided in addition to a fuel pump (14). The delivery pump (15) serves to fill a surge baffle (5) and to drive a sucking jet pump (6). The fuel pump (14) draws in fuel from the surge baffle (5) and delivers it to an internal combustion engine (2). For this purpose, the fuel pump (14) is arranged in a feed line (3) in the vicinity of the internal combustion engine (2). A return line (4) leads from the internal combustion engine into the surge baffle (5).

In the case of a pressure sensor (1) a measuring cell (4) is fixed together with a retaining body (9) in a housing (2) of the pressure sensor. For this purpose, the housing (2) has a constriction (15) encircling it on the outside. A contact base (11), which is placed at the top onto the retaining body (9), is fixed by means of an inwardly bent section (18) of the housing (2), with the result that the pressure sensor (1) is closed in a sealed manner. The fixing of the retaining body (9) by means of the constriction (15) means that the pressure sensor (1) is also suitable for particularly high pressures with the risk that the retaining body (9) could slip in the housing (2) due to the pressure acting on the measuring cell (4) being excluded.
