Abstract
A fuel supply device (), particularly for an internal combustion engine (), is equipped with a particulate filter and a water trap. In order to improve the separation effect, while simultaneously reducing the separation material that is required, it is proposed to configure the water trap () as a separate component connected downstream of the fuel filer () and to provide it with a first separation stage made of coalescent material and a second separation stage made of hydrophobic material, and to dispose the separation stages such that between them the fuel is diverted.
