Symptoms of a Bad Fuel Filter

The fuel filter is usually a round filter located close to the fuel pump. Sometimes it can also be a small square filter located behind the fuel pump in the fuel line.

As the fuel travels through the fuel line, it comes into contact with the filter material. The large particulate matter is filtered out, and it eventually comes into contact with the fuel pump, preventing these larger particles from entering the engine.

There are times when the filter can get clogged. This is when the fuel begins to flow slower or slows down considerably while the engine is running. This can mean that it takes a longer time for your vehicle to reach full power when you’re going from zero to 60.

There are different warning signs that the filter needs to be replaced. Here are some of them.

Your vehicle is harder to start. Your vehicle’s engine has a hard time starting when it’s time for you to head out. This may be a sign that the filter is getting clogged. You can easily check this by trying to start your vehicle first thing in the morning after it has been parked overnight. If you notice that it takes a really long time for you to get your vehicle started in the morning, this could be the sign that your fuel filter is bad and needs to be replaced.

Should You Clean or Replace the Fuel Filter?

Cleaning or replacing the fuel filter is essential to the longevity of your vehicle. However, understanding when to replace the filter is equally important.

So when should you replace a fuel filter? And what does the fuel filter do anyway, aside from filtering the fuel that goes into your fuel tank?

It’s clear that a clogged fuel filter can cause your vehicle to run poorly and stop suddenly without warning. However, if you’ve ever had your fuel filter clogged, you know how important it is.

You may not realize it, but the fuel filter does more than just separate the fuel from the junk you put in your tank. It’s also essential for three basic reasons. Also, in case you’re looking for it on your car, you can find it under the hood of your vehicle.

Reason 1: Fuel Filter Protects the Engine

If you plan to run your vehicle regularly, then you should be thinking about the various moving parts within your engine. Other vehicles may not have a fuel filter for this reason.

Fuel is essential to keep the engine running and one part of that is protecting the moving parts within your engine. The fuel filter is uniquely positioned to handle that without causing much of a problem. It can stop pressure surges within the fuel line and prevent the surge from affecting the rest of the engine.

When Should You Replace Your Fuel Filter

The fuel filter is another important part of your car that you should be paying attention to. Signs it is getting low include:

The gas mileage goes down.

You start to see signs of black exhaust.

There’s a funny smell coming from the gas tank.

The car is hard to start.

It takes longer to stall.

Being vigilant about the status of your fuel filter will help you avoid big repair bills in the future.
