Fuel filter replacement cycle

The recommended replacement cycle of fuel filters should be different according to their own structure, performance and use, and can not be generalized.  The recommended replacement cycle of most automakers for normal maintenance of their external filters is 48,000 km;  The recommended replacement period for conservative maintenance ranges from 192,000 km to 24,000 km.  If in doubt, consult the owner's manual to find the correct recommended replacement cycle.  

In addition, when the filter hose is aged or cracked by dirt, oil and other dirt, the hose needs to be replaced in time.
