Abstract:
Fuel delivery modules are already known having a tank flange and having an accumulator pot which is connected to the tank flange by means of at least one guide rod and which is mounted so as to be axially movable along the guide rod, where the guide rod is pressed with one end into a receptacle of the tank flange. It is disadvantageous that the receptacle is expanded over the entire longitudinal extent as the guide rod is pressed in. As a result of tolerance fluctuations in production, excessively high pressures can occur in the receptacle here, which pressures can cause cracks in the receptacle. This leads to rejects and therefore to high production costs. In the fuel delivery module according to the invention, damage to the receptacle during assembly is prevented. According to the invention, it is provided that that end of the guide rod which faces toward the tank flange has a bead, which interacts in a retentive manner with the receptacle, and a constriction situated behind the bead in a direction facing away from the tank flange.
