There is NO external fuel filter in the gasoline fuel system of Peugeot 308!!!

There is only the coarse mesh located on the pump in the fuel tank and the fine mesh filter located in the tank body. This filter should to be replaced every 60-70 kilometers of the run.

Also, it is possible to dissemble the fine mesh filter located on the pump.
