Change your fuel filter every two years or 24,000 miles, whichever comes first. Auto technicians often change fuel filters during routine tune-ups, though some people learn to change their own fuel filters.
The fuel filter is between the fuel pump and fuel tank. Its main job is to remove debris and pollutants that would otherwise enter the engine. If the engine is making odd noises, it might be due to a clogged filter, which requires a filter change. If you want to change your own fuel filter, you need fuel line washers, wrenches, screwdrivers, a car jack and a jack stand.
