Abstract

A fuel filter system, particularly a diesel filter, including a housing, a particle filter arranged in the housing, and a coalescer element mounted on the particle filter. Fuel passes successively through the serially connected coalescer and particle filter. The coalescer element improves the separation of any water contained in the fuel to be filtered, while exhibiting no or no significant fuel-filtering properties.
