Size Matters When Choosing a Fuel Filter

One of the key factors that are heavily considered when choosing a fuel filter is the size or the surface area. Other key factors you should also have in mind include the port size, housing design, and porosity.

To ensure you reap all the benefits of a fuel filter, only source it from an authentic dealer. And, you should also maintain it well so that it can serve you for longer.

The correct size fuel filter will promote easy flow of fuel within the system. Your engine will perform better. However, if it is not the right fit, you can forget about proper fuel flow.

It is also crucial that you learn how to change and maintain fuel filters. Above, we have already addressed the issue of fuel filter size. Let’s look at other things that you need to know about fuel filters.

What is a Fuel Filter?

The fuel filter, even though it isn’t as highly prioritized as other parts like the oil and air filter. It is still a very important part of the car.

As pure as the gasoline you get at a gas station is, quite often impurities and debris do find their way into your fuel tank. The fuel in your tank is heavily relied upon by the engine so that power can be generated.

If these impurities find their way into the engine, they can clog it and this can damage your engine which is the most important part of your car.

The fuel filter prevents this from happening by filtering particles and other impurities before the fuel enters the engine. Because of your fuel filter, the gasoline entering your engine is usually in its purest form.

Depending on where you get your fuel from, the fuel filter needs to be replaced whenever it gets clogged.

There are different types of filters with some having more features than others. As a car owner, it is up to you to find out which filter suits your car best.

What is the Purpose of a Fuel Filter?

When we talk about the purpose of a fuel filter, most people think that debris is the only thing that can block your filter. However, there are so many things out there that can make your fuel impure.

One of the impurities that can find its way into your engine is rust from your fuel tank and paint chips. When these fall into your fuel, they get carried along the fuel line into the engine.

Other impurities that can find their way into your engine include sand, soot, and dirt. Also, microbial growth in the tank can add toxins to your fuel and the results will be catastrophic.

A fuel filter prevents all the above particles, impurities, and toxins from finding their way into your engine.

And that’s not all, a clean and well-maintained fuel filter boosts your engine’s performance, reduces smoke coming from the exhaust which is often caused by the engine burning incomplete fuel.

It also prevents overheating and corrosion of the engine.

Where is the Fuel Filter Located in a Car?

If you are considering changing the fuel filter, it is imperative that you know where it is located. Different car models place their filters in varying locations. However, we are going to give you a clue on where you can expect to find yours.

In all cars, the fuel filter is located somewhere between the engine and the fuel tank. In some, you will find just near the opening of the fuel line which is the area where you feed gas to your car.

In some models, the fuel filter is located along the fuel line which should be at the bottom of your car.

To know the precise location of your car’s fuel filter, look at your car’s manual.

They will have indicated its exact location. Please, if you aren’t conversant with fuel filter removal or installation, take your car to the mechanic.

Failing to properly install the fuel filter can lead to a number of problems with your engine. So, you should do it correctly.

Why Do I have to Change My Fuel Filter?

Though not as often changed as other filters in the car, your fuel filter gets dirty, clogged, and worn out after years of use.

Most car owners don’t pay much attention to the condition of their fuel filters until it affects the flow of fuel into the engine and slows down the performance of the vehicle.

Your car’s fuel filter needs to be changed after every 30,000 to 60,000 km. However, most cars can use the same filter for up to 100,000 km.

if you are one who prefers to change cars after a few years, chances are, you may not even have to change the fuel filter.

People who buy used cars need to change or at least have a look at the condition of the fuel filter is because in most cases, people forget about this crucial part of your fuel system.

Using the same fuel filter for more than 100,000 km is a recipe for engine failure or total damage.

Is Fuel Filter the Same as Oil Filter?

When most people hear about filters, their minds quickly run to oil filters. This is understandable because oil filters are the ones that are commonly changed when a car is being serviced.

But they are very different from fuel filters. Other than being bigger, oil filters filter oil coming from the reservoir tank to the engine.

Despite both doing the same job, they filter different liquids that are oil and fuel. Also, they are located in different places.

Oil filters are found around the engine. Whereas fuel filters are a bit further and are near fuel tanks.
