The fuel filter is an important component of an automobile's fuel delivery system. The fuel filter prevents dirt and debris present in the fuel from entering the components of the engine. This ensures optimal function of the engine. Therefore, having clean fuel filters are important for your automobile. In this article, we will discuss all you need to know about the fuel filter of your vehicle.

1. All You Need to Know About the
Fuel Filter of Your Vehicle

2. The fuel filter is an important component of an automobile's fuel
delivery system. The fuel filter prevents dirt and debris present
in the fuel from entering the components of the engine. This
ensures optimal function of the engine. Therefore, having clean
fuel filters are important for your automobile. In this article, we
will discuss all you need to know about the fuel filter of your
vehicle.

3. Function
The fuel filter stalls dirt and debris from entering the engine.
This is important because, dirt and debris will impair the
burning of air-fuel mixture. In addition, they will clog up the
fuel injectors, which further causes insufficient fuel supply to
the engine. This results in suboptimal performance of the
engine.
Types
Fuel filters can be divided into two categories: in-line and tank
filters. An in-line filter has an inlet and an outlet. Whereas, a fuel
tank filter comprises a fine wire mesh, which is placed inside the
fuel tank.

4. Locating a fuel filter
The fuel filter is positioned inside the fuel tank, or between the
fuel pump and the fuel tank. In modern cars, the filter is located
outside the engine and is attached to the fuel supply line. Thus,
you can locate the fuel filter going along the fuel supply line.
Symptoms of a faulty fuel filter
The fuel filter gets clogged up over time with solid particles
brought by fuel and it can become faulty. Faulty filters can be
identified by the following symptoms.

5. The vehicle loses power when you are driving up an incline, or a
small hill.
During this time, your car needs more power by consuming
more fuel. A clogged fuel filter will not let this happen because
the amount of fuel the clogged filter sends is lower than
required.
Even if you accelerate, the vehicle will not move faster.
Your vehicle may stop suddenly and you cannot start it again.
The exhaust smoke may have a typical smell.

6. Inspecting a fuel filter
You need to check whether the fuel filter allows easy passage of
air through it. For this, blow through the hose. If the filter is in
good order, it will allow you to blow through it with ease – it
will restrict little or none.
Proper maintenance
Appropriate maintenance of the fuel filter is essential to keep
your car in good order. The owner’s manual may explain how to
do the job. You need to clean or get the filter cleaned up as
recommended by the manufacturer. If the filter is old enough -
two years; or if you have driven 24,000 miles, it's time to
replace the fuel filter.

7. The fuel filter plays an important role in the fuel delivery system
of your vehicle. If it's not functioning optimally, it will lead
more workload on the fuel pump, the fuel injectors and other
vital parts which leads to engine failure.
