The fuel filter is designed to trap particles that may cause the fuel supply system to malfunction. It is installed under the metal cover 27 (Fig. 206) next to the fuel tank 24. The filter is built into the supply line between the fuel pump and the fuel distribution line. There is an arrow on the filter that indicates the direction of fuel flow. Pay attention to this when installing a new filter. The filter has a long service life, so it does not require replacement during technical inspections and maintenance work on the car. It should only be changed if it is clogged.
