We clean the filter without removing the pump from the car.
1. We prepare the car for operations (see "Vehicle preparation for maintenance and repair").
2. We clean the dirt with a rag and wash the outer surface of the fuel pump with white spirit or engine cleaner.
3. Using a 10 mm wrench, unscrew the bolt securing the top cover of the fuel pump.
4. Remove the cover and take out the filter.
5. We wash the filter with a carburetor cleaner or acetone and blow it with compressed air.
6. Install the filter and assemble the fuel pump in reverse order.
