Where Is The Fuel Filter On The Trimmer

The trimmer is an irreplaceable thing on a garden site. If you want to maintain the beauty of the lawns in the country, the trimmer will help to quickly cut the grass with minimal effort.

Like any other equipment, it needs careful operation. First of all, it is necessary to timely replace the fuel and air filter.

At the same time, it is completely optional to give the equipment to the service. Anyone can cope with the task.

Where Is The Fuel Filter On The Trimmer

Types and principle of operation of filters for trimmer

In modern lawn mowers, two types of filters are used. Fuel and air.

  • Fuel filter for trimmer

Even the highest quality fuel has various additives that quickly accumulate and disable equipment.

The task of the fuel filter in gas trimmers is to protect the engine of the device from various impurities that are contained in gasoline and oil.

Outwardly, it is very small. They make it from felt material. The manufacturer places the compactly folded felt in a metal tip and places it on the intake pipe inside the fuel tank.

Another placement option is in the line between the carburetor and the tank. Many trimmer owners even note overly thorough cleaning, so the material quickly becomes clogged so badly that it requires a complete replacement.

  • Petrol trimmer air filter

Its main purpose is to keep dirt and dust coming into the trimmer from the outside during operation.

When mowing, not only dust often rises into the air, but also small litter, ground grass, which can quickly clog the equipment. A good filter will prevent engine damage even if the air is very dirty.

Its location may vary depending on the trimmer model, but is usually located on the side of the device under a protective cover.

The casing is fixed either to the bolt or by latches, which are very easy to open to remove the contents. The filter itself can be made in the form of a ring or plate of foam rubber, felt, fleece.

If you mow on average 1-2 times a week, then replacing will be enough at least once a year. For more intensive use, inspection and replacement should be carried out more often.

How to clean the filter on the trimmer

Sooner or later, there will necessarily be a need rinse the Husqvarna trimmer air filter or any other manufacturer. There is nothing complicated, and you can remove pollution from it yourself a couple of hours before mowing.

To do this, proceed as follows:

  1. Unscrew the bolt on the protective cover or wring out the latches.
  2. We take out the filter and inspect. To remove all accumulated oil and other contaminants, gasoline is required.
  3. Pour gasoline from a canister onto a dirty filter and wash off all the oil. Squeeze and leave to dry for at least 2 hours.
  4. We wipe the installation site with a cloth soaked in gasoline.
  5. We install everything in place and close the casing.


Instead of gasoline, you can use soapy water, but it removes dirt is still not as effective.

As an alternative to flushing, you can advise blowing or just shaking out the litter. These cleaning options are suitable if there is no oil contamination.

Trimmer fuel filter replacement

If the trimmer starts to stall at high speeds, most likely the fuel filter is so dirty that it needs to be replaced immediately.

To replace it is completely within the power of everyone. You can stick to the following algorithm.

The first thing to do is to remove the intake pipe (see), since the filter itself is inside the fuel tank. To do this, we pull the pipeline towards us with our hands. When removing the seal, the intake pipe should come off and remain in the tank. Tweezers will help to remove it from there. You can also drain gasoline from the tank and pull the intake pipe through the hole.

We take a new filter, we put on it an intake pipe and a spring ring.

We install the o-ring back onto the pipeline, we attach the intake pipe with a new filter to it and fill it into the tank with the pipe.

We put in place a sealing ring. Turn a little around its axis so that the connection is fixed.

We pump the carburetor using a booster pump.

Fuel filter, and in English it sounds like Fuel Filter. This filter element of the fuel system is designed to filter out particles of dust, dirt, debris and rust from the fuel mixture to prevent their penetration by the fuel supply system. This avoids the creation of plugs in the fuel pipes, as well as clogging of the nozzles.

Types and principle of operation of the fuel cleaning system

The fuel filter scheme of a modern car requires at least two degrees of purification. At the first stage, rough cleaning is carried out, during which large debris is screened out. The second stage is fine cleaning with another filter, which is considered the main one. It is impossible to give an unambiguous answer to the question of where the fine fuel filter is located, since its exact location depends on the car model and the type of fuel system implemented in it. But in any case, it is installed between the engine and the fuel tank, while in the tank itself, even before the gasoline pump, a coarse filter is placed.

Fuel filter device

The type of filter installed in the car depends on the type of fuel supply system, which can be:

  • Carburetor;
  • Injection;
  • Diesel.

Fuel filters depending on the type of fuel system.

Where is the fuel filter located?

To the question where is the fuel filter fine cleaning cannot give an unambiguous answer, since its exact location depends on the model of the car and the type of fuel system implemented in it. But in any case, it is installed between the engine and the fuel tank. Often a filter is installed. Under the hood, under the bottom or in the fuel tank cars with a fuel pump and a fuel pre-filter.

In carburetor system the filter is installed in front of the carburetor. Most often, it is made in a translucent housing to facilitate clogging control. This design allows you to visually determine when changing the fuel filter becomes extremely necessary. Filters for carburetor engines are the simplest, since such engines are not too whimsical in terms of the cleanliness of the fuel mixture.

In injection engines Due to the use of nozzles, high-quality filtration with screening of particles with a size of 10 microns is needed. Given this, as well as the high pressure in the fuel supply system, the fuel filter itself is most often made of metal, and the filter element needs regular maintenance and cleaning. These filters are located under the bottom of the car, which simplifies access to them.

In diesel engines fuel cleaning must be of high quality due to increased sensitive fuel equipment. Since diesel fuel has a lot of moisture, filters for such engines are different from gasoline ones, because they must condense and remove water from the fuel mixture. Well, and there is a fuel filter in diesel engines, also between the fuel pump and the engine.

It should be noted that due to the content of paraffins in diesel fuel, filters are often equipped with heating, since this substance crystallizes in the cold and can quickly clog the filter element.

Replacing the fuel filter

Carburetor cars are quite old, and there are no difficulties in replacing the filter, since you just need to remove two tubes and change the element, so you won’t dwell on this in detail, but you can consider not changing the fuel filter of an injector car and diesel so that their owners do not made hasty mistakes.

To replace the fuel filter on a gasoline or diesel car, you will need a standard set of tools: a wrench or socket wrench, a screwdriver, pliers, etc.

Replacing fuel filter gasoline

On injection cars, the filters of which are under the machine, in the area of ​​the fuel tank, it will be easiest to change, because there you need to:

  • Unscrew the clamp
  • Remove the fuel pipes on the sides (can be both on clamps, can be removed with pliers, and plastic quick couplings, you need to press on the sides).

On “gas tanks” with a filter installed in the tank (the so-called fuel station), the procedure is a little more complicated, because you will need:

  • Remove the rear seat
  • Open the hatch
  • Unscrew the fixing nut
  • Remove the hoses
  • Fuel pump power connector,
  • Disassemble the fuel station housing in order to separate the fuel filter itself.

Replacing the diesel fuel filter

Diesel engines are not only the most powerful, but also the most demanding on fuel quality. Due to the fact that diesel fuel has many different impurities and moisture. The filter of such cars differs from the filters of gasoline cars like an injector or a carburetor, therefore the replacement of the fuel filter of a diesel car is also significantly different.

To replace the fuel filter of a diesel engine, a manual booster pump (bulb) and a tank for draining / pumping fuel may additionally be required. So itself, as in the previous version:

  • All fasteners are unscrewed
  • Fuel hoses are disconnected from the filter cartridge,
  • You need to remove the water sensor connector (if any)
  • And change the filter.

But if there is a removable filter element in the case, then the task is complicated, and it will also be necessary to remove water and dirt. After replacing on many cars with a diesel engine, in order to fill the filter with fuel, you need to use an additional booster pump to avoid airing the fuel system. All details of the procedure must be seen in the repair manual for a particular car!

When to change the fuel filter?

Often, according to many drivers of the fuel filter service strings from 30 thousand km mileage on diesel cars, up 60-100 thousand km working on gasoline.

Automakers often claim that the service line of the fuel filter on their car is equal to the resource of the car. However, such statements are not at all realistic for our operating conditions and fuel quality. A fuel filter cannot provide good throughput for such a long time. So how often to change the fuel filter and what quality each driver decides to set for himself.

In especially advanced cases, a dirty fuel filter may look like this.

Fuel Filter Symptoms

The following signs indicate that the filter is clogged:

  1. Uneven motor operation;
  2. A noticeable drop in engine power in the absence of other problems with it;
  3. Increased fuel consumption.

In the fuel system of an injection vehicle, the fuel filter of primary cleaning (in the gas tank) is the first to suffer from low-quality fuel.

As a rule, the problem with clogging appears gradually, and the symptoms immediately look very slight, increasing over time.

Fuel filter error

One of the signs of a problem with the filter can also be a decrease in pressure in the fuel rail, this will be indicated by the engine receipt indicator on the panel and error code P0087, which can be quickly read by the scanner Scan Tool Pro Black Edition. It is enough just to insert it into the diagnostic socket of the computer and connect from the phone through any available application via Wi-Fi or Bluetooth.

Of the 4 main reasons for the occurrence of an error in fuel pressure, a clogged fine fuel filter or a rough one (fuel pump mesh) is precisely the main problem that affects the fuel pump itself and the entire fuel system. The ability of the scanner not only to read errors, but also to look at the performance indicators of the sensors responsible for fuel supply and dosing, will help to more accurately establish the cause.

Decryption of diagnostic code p0087

Notification on the dashboard of a diesel car about the need to replace the fuel filter

On some cars there is also a sensor that is responsible for the indicator about the need to replace the fuel filter, however, it can give such a signal to the panel not only with a blockage or a large amount of water in the filter (in diesel cars), but also just bad fuel. Scanner Scan tool pro, which has a 32-bit chip, and not 8 as its counterparts, this fact can be checked and, in the event of a false positive, throw an error. Also, this device will allow you to check both the engine and other components and assemblies of the car (gearbox, transmission, auxiliary systems ABS, ESP, etc.).

Causes of fuel filter breakdowns

Most often fuel filter fails due to low-quality fuel mixtures. This leads to clogging or less likely corrosion of the filter element. In the first case, the fuel flow along the highways is hindered, in the second, the nozzles and other engine parts become clogged and fail.

Frequently asked Questions

Where is the fuel filter located?

The exact location of the fuel filter depends on the layout of the vehicle. In carburetor machines, it is usually located under the hood next to the carburetor. In diesel vehicles in the engine compartment between the high-pressure fuel pump and the engine. On injection cars it can be located under the bottom, in the engine compartment or in the fuel tank of the fuel pump module. Exact information on the location of the fuel filter is indicated in the car’s operating instructions.

What does a fuel filter look like?

In carburetor machines, it looks like a transparent plastic case with a filter element inside. In modern machines, due to the high pressure in the fuel system, fuel filters are made as more massive metal or thick plastic flasks with filter elements inside. The average size of the filter. From 10 to 20 centimeters in height, up to 10-12 centimeters in diameter, although deviations are possible. Diesel fuel filters can be more complex in construction because they must filter moisture and paraffins.

How does a fuel filter work?

Fuel enters the filter housing, passes through the layers of the filter element and, when cleaned, leaves the filter further into the fuel system.

When does the fuel filter change?

The exact time for replacing the fuel filter is in the “manual” of the car or you can find it at the service station of an authorized dealer in the manual on technical inspections of the car. All other recommendations can be considered too average to be advised to all car owners. The average service life of the fuel filter is at least 40-60 thousand km. Change when clogging symptoms occur or according to the maintenance schedule.
