The fuel filter removes built-up sediment in the gas to prevent particles from reaching the internal combustion engine. Over time, it becomes clogged, and driving with a clogged unit may require eventual engine auto repairs. Keep your car running smoothly by having the filter checked whenever you notice the signs below.

How to Know When Your Fuel Filter Needs Replacement

1. Trouble Starting

If the filter is clogged, the gas flow may be restricted, preventing the vehicle from starting even with a full tank. A faulty fuel pump or alternator can also prevent the engine from turning over, so only a mechanic can accurately diagnose the root cause. However, if you’ve never had the filter changed, this might be the issue.

2. Fluctuating Power

If you experience a change in engine power while driving, the fuel filter likely needs replacement. Drops in power are typically more noticeable when you drive on an incline because the motor has to work harder to push the vehicle.

3. Lit Check Engine Light

Your vehicle may warn you of filter problems through the check engine light. Modern cars have sensors that monitor fuel pressure and the amount of gas flowing through their systems. A dirty filter reduces gas flow, triggering this warning.
