The fuel filter contains a paper element that keeps most dirt and sediment from entering the fuel system. Clean fuel is especially important on fuel injected engines, due to the small orifice size of the injectors. Even the smallest piece of dirt could clog an injector, causing serious engine performance problems.
Although the manufacturer does not give a specific inspection or replacement schedule, it is a good idea to replace the filter at 30,000 mile (48,300 km) intervals.
