A lid is attached to the cylindrical wall and closes off the second end face. The housing has two layers of different plastic materials, wherein the different plastic materials have different ductility and in particular different hardness. The cylindrical wall has elements that provide a positive-locking connection of the two layers in the axial direction of the housing.

Filter, in particular a fuel filter

A fuel filter has a filter housing and an annular filter element arranged in the filter housing. Between the bottom of the filter housing and the bottom area of the filter element a water collecting chamber is formed. The filter element has a coalescing element and a particle filter element. Fuel flows radially from the interior to the exterior of the coalescing element and from the exterior to the interior of the particle filter element. A riser tube extends through the clean chamber and the raw chamber from the bottom of the filter housing to the top. The riser tube has a clean channel and a guide channel. A seal on the riser tube separates a clean chamber from a raw chamber of the filter. A water removal tube is arranged inside the guide channel for removing water from the water collecting chamber.
