The recommended replacement period of the fuel filter should vary according to its own structure, performance and purpose, etc., and cannot be generalized. Most automobile manufacturers recommend a replacement period of 48,000 km for normal maintenance of their external filters; the recommended replacement period for conservative maintenance is 192,000 to 24,000 km. If in doubt, please refer to the owner’s manual to find the correct recommended replacement period.

In addition, when the filter hose has aging or cracks caused by dirt, oil, etc., the hose needs to be replaced in time.
