Fuel filters clean a car's oil or fuel before it reaches the engine. Unfortunately, they can become clogged with dust, dirt, and debris over time. Most car manufacturers recommend changing fuel filters every 24,000 miles to avoid engine failure. However, these auto parts sometimes need to be replaced sooner, especially if you experience any of the following issues with your vehicle.

When Does Your Fuel Filter Need to Be Changed?

1. Engine Malfunction

Dirty fuel filters can cause fuel inefficiency, leading to difficulty in starting your car. A fully clogged filter prevents the engine from working altogether. This is because the fuel and air can't pass through, and both are needed to combine at the correct ratio for combustion.

2. Dashboard Light

Check engine lights can turn on for various reasons, but many cars now feature fuel pressure sensors that monitor a vehicle's fuel amounts as it travels through the vehicle's system. A clogged fuel filter often triggers a sensor failure, causing the check engine light to engage. An experienced auto technician will inspect your fuel filter when diagnosing the reason for the light coming on.

3. Strong Fuel Odor

A dirty fuel filter could be leaking fluids if you smell strong fumes coming from your vehicle's exhaust after driving. When fuel can't pass through this auto part, leaks can occur at the filter's fittings or body. While there are more common causes of fuel leaks—such as a damaged fuel line or broken spark plug—a clogged fuel filter is possible, primarily if it occurs alongside another telltale symptom.
