1. Field of the Invention
The invention is based on a pumping assembly.
2. Description of the Prior Art
An electric fuel pump is already known from German Utility Model DE 91 12 096 U1, having a pump housing and a ground terminal, provided on a terminal cap, for making contact with an electrical ground, the pump housing and the ground terminal of the terminal cap being connected to one another via a ground connection which has a first contact portion for making contact with the pump housing and a second contact portion for contacting to the ground terminal. The first contact portion is provided on the outer circumference of a terminal cap, and after installation, it is pressed with a contact pressure against the inner face of the pump housing. However, since the inner face of the pump housing is increasingly provided with an electrically insulating anticorrosion coating, when the terminal cap is pressed into the pump housing a touch contact with the pump housing is created that in most cases is also electrically conductive, but because of the electrically insulating coating, it has a high electrical resistance and a high impedance. However, for good electromagnetic compatibility of the pumping assembly, low-resistance or low-impedance contact-making is required.
