A fuel filter keeps your car engine running smoothly by removing unwanted debris from entering the motor. This might be dirt from the road, leaves, or other types of debris that could damage the engine. If it becomes blocked or doesn’t work properly, it could affect the performance of your car or even cause you to break down, so it’s important to get it replaced.

What is a fuel filter?

A fuel filter blocks unwanted debris from entering the engine while you’re driving. This can include dirt, dust, leaves, and other debris on the roads that could seep through the vent into the engine. It stops anything untoward from accessing the combustion chamber, which could cause your engine to stop working correctly. It doesn’t matter if you own a petrol or diesel car, a fuel filter work in the same way, and if it becomes damaged, you’ll need to get it replaced.

How often should you change a fuel filter?

How often you need to replace the fuel filter depends on the make and model of your car. On average, you’ll need to change the car fuel filter at around 30,000 miles, but they can last anywhere up to 60,000 miles in some cars. If you’re unsure, or you think the car fuel filter may need replacing, visit your local Halfords store where our technicians can lend a helping hand and check over your vehicle.

Fuel filter FAQs

The fuel filter is located between the fuel tank and car engine. It’s called an inline fuel filter because it sits in the middle of both. It can also be found on or inside the fuel tank in some vehicles.

It varies from vehicle to vehicle, but it’s usually a straightforward process if you have the part you need and know how to operate a car’s mechanics. For more details, read our step-by-step guide.

Fuel filter replacement costs vary depending on the make and model of your vehicle, as well as the brand of water pump used. Enter your vehicle registration number and we’ll show you the correct fuel filter for your car, alongside other products designed for your vehicle.

We strongly advise against driving a car without a fuel filter. Without it, debris and dirt could make its way into the combustion chamber which could damage your car’s engine.
