Some Duster may not have the filter element itself in the fuel filter body.
Previously, the fuel filter was installed from the outside, just in this case, it is now integrated into the fuel pump. This empty shell is used as a connector to avoid making changes to the design of the fuel system and not to increase the cost of car production.
The service record contains a list of operations performed during maintenance of Duster:
-Engine oil replacement
-Replacement of the oil filter
-Verification of the exhaust system
-Water filter of diesel engine (if no filter replacement is due)
You can conclude from this list that no replacement of a fuel filter is required.
