Abstract

The invention relates to a fuel supply system for an internal combustion engine, having a unit such as a pressure regulator, mounted in electrically insulated fashion and including an electrically conductive housing, and the housing is connected via an electrical connection to a defined electrical potential. As a result, static charging of the unit, which could become dangerous, is precluded. The fuel supply system is intended in particular for pumping fuel to an internal combustion engine of a motor vehicle.
