Abstract
A fuel supply device (1), particularly for an internal combustion engine (6), 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 (5, 8, 30) as a separate component connected downstream of the fuel filer (4) 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.

Fuel supply device (1), in particular for an internal combustion engine (6), comprising a particulate filter and a water separator, characterized in that the water separator (5, 8, 30) is embodied as a separate component downstream of the fuel filter (4) and comprises a first separating stage (A1) with coalescent material as well as a second separating stage (A2) with hydrophobic material and wherein the separating stages (A1, A2) are arranged such that between them a diversion of the fuel is realized.
