What Is the Fuel Filter?
Your fuel filter’s function is basically the same as other filters in your car, like for air, oil, and inside your transmission. Fuel can sometimes get contaminated with particles or random gunk. This could happen because of rust inside your fuel tank, though most tanks are plastic these days to prevent that. It could also come from the gas station if their tanks and filtering systems aren’t up to snuff.
Every car has a fuel filter somewhere between the fuel tank and the engine to capture these stray particles and keep them from getting into your engine.
What Happens If You Don’t Replace the Fuel Filter?
Any particles the fuel filter captures sit there and don’t go anywhere. Over time, if it captures too many particles they may start blocking the flow of fuel to your engine. In addition to causing not enough fuel to reach your engine, it also makes your fuel pump work harder to push it there, which can cause premature failure. Replacing the filter from time to time prevents too much crud from building up inside and restricting fuel flow. It’s worth the cost of a fuel filter change.

How Often to Replace the Fuel Filter
Generally speaking, you usually perform this service every 30,000 miles or so. The manufacturer’s recommended maintenance schedule will tell you how often to replace the fuel filter in your particular car.
If the manufacturer recommends a particularly long service interval, like 100,000 miles, consider replacing your fuel filter more frequently than recommended. It does no harm to have a clean filter and could extend the life of other components.
Common Symptoms You Need to Replace Your Fuel Filter
- The engine cranks, but won’t start
- Rough idle
- Reduced power
- Engine turns off while driving or idling
