• Poor Engine Performance: The speed and handling of your vehicle seem worse, especially at high speeds, inclines, or while carrying heavy loads. The engine may surge, sputter, and you may have difficulty turning.
• Engine Idling and Stalling: A clogged fuel filter will cause the engine to stutter and stall at low speeds, with more intense idling bounce.
• Misfiring Engine: A clogged fuel filter can cause uneven fuel distribution and low fuel pressure, leading to engine misfires.
• Trouble Accelerating: A clogged fuel filter restricts fuel flow, resulting in insufficient fuel to accelerate the vehicle.

Fuel filter maintenance

The fuel filter in your car performs a critical function: it prevents contaminants from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining. As such, it's important to keep your fuel filter well-maintained.

The frequency with which you should replace your fuel filter depends on the age and model of your car. Older cars may need their filters replaced as often as every two years or 30,000 miles. Newer vehicles can often go as long as 50,000 miles before needing a change. However, it's always a good idea to consult your owner's manual for specific recommendations for your vehicle. Additionally, factors such as your driving habits and the conditions in which you drive can also impact the replacement frequency.

Signs That Your Fuel Filter Needs Replacing

There are several signs that indicate it's time to replace your fuel filter. These include:

• Problems with starting your car, or it takes multiple attempts
• Stalling, especially while idling at a stop sign or red light
• Excessive vibration while driving
• Rough slow-speed cruising—your car may be fine at highway speeds but struggles at slower speeds

How to Confirm a Clogged Fuel Filter

If you suspect that your fuel filter is clogged, there are a couple of ways to confirm:

• Perform a fuel pressure test: You can rent a fuel pressure tester from stores like AutoZone. Before performing the test, ensure your gas tank has fuel (don't just rely on the gas gauge) and that the fuel pump is working. Then, follow the steps outlined in the fuel pressure tester instructions.
• Visual inspection: Place an oil drain pan or bowl under your car to catch any fuel leaks. Remove the fuel filter using a fuel filter removal tool, and then take it apart. Pour out the fuel and observe its colour. If it's rusty or brown/orange, your fuel is dirty, indicating a clogged filter or a rusted component within the filter. If no fuel comes out, there's a clog in the line.

Where Can I Get My Fuel Filter Replaced?

You have two main options for replacing your fuel filter:

• Dealer service centres: These centres specialise in one or two car makes and sell those vehicles. They use top-quality manufacturer-recommended parts and offer warranties. Their labour rates may be higher due to their high level of training and knowledge.
• Independent service centres: These centres service multiple car makes and may offer lower prices as they can use non-official or aftermarket parts. Their technicians tend to have a broad level of knowledge and training on various vehicles.

Additional Maintenance Tips

When replacing your fuel filter, it's a good idea to also check other components, such as your serpentine belt, air filter, and spark plugs. Additionally, consider using a fuel system cleaner, such as Seafoam, at every oil change to keep your fuel system clean. Finally, try not to let your tank run too low on fuel, as this can negatively affect fuel pump life.

Fuel filter location
