Manufacturers recommend changing the fuel filter on a brand car every 15 thousand kilometers. However, if this part of the car becomes clogged, it must be done much earlier. The first call for problems with the filter is jerking the car at low speeds or high gears.
Its main purpose is to retain foreign impurities and prevent them from entering the fuel system. Thus, the barrier protects the car's engine from clogging and increases its performance.
2 can even a novice motorist. The whole process does not take much time and does not require special skills.
However, in cars manufactured in 2007, 2008, it is different, and also depends on the type of engine fuel: gasoline or diesel. In this article, we will present a step-by-step manual for, as well as provide you with the corresponding photo and video.
Filter replacement instructions
On Renault Megane s models manufactured before 2007, 2008, the filter is found outside the tank. To find it, just look under the car. It is best to use a flyover or a lift to mount the part on a car in 2007, 2008. You can remove the worn part by clicking on the square green tabs, as shown in the photo.
Next, simply remove the barrier and install a new one, not forgetting the direction of the arrows indicated on the filter. For understanding, the arrow on the part indicates how gasoline moves through this part: in the direction from the hood to the trunk. Fasten the fuel hose clamps until you hear a click.
All the details of the process can be seen on the video. 
Diesel Fuel Filter Replacement
Initially, you need to remove the right front wheel and the part of the fender liner located closer to the front area of \u200b\u200bthe Megan car. Lift the filter up and remove it from the bracket. After, turn off the power by lifting the latch and pulling the cable back, as indicated in the photo.
Then we slightly swing the connector from side to side and pull it up, thereby disconnecting the fitting from the pipe (the one through which the fuel enters the filter and the one through which it flows out of it).
In the upper area of the barrier, unscrew the screw with a screwdriver. We are replacing the seal on it. We remove the top cover, remove the old barrier and install a new one. We assemble all the parts in the reverse order and install the structure in the car.
Remove the rubber cap from the drain and pump fuel from the tank to the barrier. To do this, you need to press several times on the pear with coolant, which is located under the hood, behind the reservoir. After the fuel flows through the drainage, we twist the rubber cap.
Well, to check the correctness of the work done, we start the engine.
The video will help you avoid mistakes in the process.
Subtleties of filter replacement for second generation models
The barrier at the second phase (for models 2007, 2008) Renault Megan is located in the tank and has a different installation procedure. It can be changed as an assembly with the pump, or you can only replace the mesh, which is the barrier on models 2007, 2008.
- Using long-nose pliers and a chisel, remove the latches from the fuel pipes.
- After we get the fuel pump itself. We remember the location of the minus and plus and remove the terminals from the fuel pump motor.
- We dismantle the bottom cover, and then the mesh barrier.
- Rubber rings from the previous pump are put on a new one, after which it is installed in the housing and the fixing bolt is screwed.
- A new tube prepared in advance is pulled over each fitting to the second risk.
- We install a mesh barrier and fix the terminals in accordance with the poles.
- In the end, we fasten the union nut, put the rubber ring of the cover on the fuel pump, fitting and connector.
- In the video below, you can follow all the features of this process for the 2007 and 2008 models.
A correctly done algorithm of actions will prevent interruptions in the supply of fuel and problems in the operation of the engine.
It is difficult to imagine how much fuel the car "eats" for the entire period of operation. And all this volume passes through a small device - a fuel filter. Renault Megan is available in several versions. Depending on the motor size, the design of the cleaning device also differs.
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!
If you take Renault Megan 2, the year of manufacture of which does not exceed 2007, then the filter element (fine cleaning) is installed under the bottom of the car next to the rear wheel on the driver's side. Thus, the designers of Renauilt have achieved convenience when replacing this unit.
Models that, according to the year of manufacture, crossed abroad in 2007, are mounted inside the unit with a pump and a sensor
The third generation gasoline Megan is no different from such samples, therefore, their maintenance principle is similar.
In cars with diesel engine options, they did not get smarter and left the same fuel filter installation scheme.
Price, originals and analogues, article
In order for the car engine to perform its functions with high quality, Renault advises to purchase only original spare parts. But, most car owners, if replacement is necessary, still buy less expensive non-original parts and components from other manufacturers. This is not surprising, because the cost of the spare part plays an important role for the driver of the vehicle.

How to replace the fuel filter yourself
As already mentioned, the design of Megane 2 in terms of mounting the filter component depends on the year of manufacture of the car. Consider the first installation option in the early models of the second series of the French.
- Before starting to replace the filter, it is better to apply double-sided tape to the new product - wrap it around the body in the area where the clamp is attached.
- Now you need to install the car on a viewing hole or raise it on a jack, observing safety precautions.
- They find the old cleaner and the latches on both sides of it are green. Here we must not forget about the presence of arrows indicating in which direction the fuel mixture is moving. The position of the new filter also depends on this.
- From the accumulated road dust and dirt, the clamps may not give in. It is necessary to clean them (wash or tap on them so that the dirt disappears).
- Remove the old filter and put a new one in its place.
On cars manufactured from the assembly line of the car factory after 2007, the cleaner is installed in the fuel pump and can be removed separately or together with the pump.
On vehicles with diesel power units, the principle of replacing the fuel pump does not differ and does not depend on the Megan generation. The work can be done independently and within the power of any beginner.
- Jack up the right side of the car and remove the wheel.
- Next, proceed to remove the protection, unscrewing the mounting screws.
- If you bend it, then access to the cleaning module opens. It is located in the casing.
- Now proceed to remove the headlight. It is not necessary to disconnect the wires.
- Pushing it aside, the fuel filter is removed through the hole in the body of the car.
- The fuel mixture heater is dismantled and installed on a new filter, not forgetting about the sealing material for the new product.
- The assembly order is in reverse order.
The procedure for replacing the fuel cleaning module is quite simple and will take only some 20 minutes. It does not require tremendous experience and knowledge, so you should not delay the installation of a new product.
After all, the performance of the car engine depends on the quality of the fuel. On autosites, you can see how to step by step perform operations to replace this important unit of the vehicle's fuel system.
Fine fuel filter - non-separable, in a steel case, with a paper filter element. An arrow is marked on the filter housing, which must coincide with the direction of fuel movement.
The fuel filter must be replaced after 15,000 km. Of course, this figure depends on the operating conditions. This refers to the quality of the gasoline being poured.
The fine fuel filter is located under the bottom on the left side, closer to the rear wheels.
The fuel in the engine power system is under pressure. Therefore, before servicing the fuel system, it is necessary to relieve fuel pressure.
Squeezing the two retainers of the fuel pipe tip, remove the tip from the filter fitting.
Similarly, remove the tip of the fuel pipe from the other filter fitting.
With a head of 10, loosen the tightening of the clamp bolt
take out the fuel filter
Install the filter in reverse order.
When removing and installing the filter, pay attention to the position of the fuel flow arrow.
The fuel filter is an element of the vehicle's fuel system. It is used for filtration to keep out small dust particles, debris and other unwanted particles along with the fuel. Dirt must not be allowed to enter the system. It creates blockages and stagnation in the fuel pipes, forming plugs in the injectors.
Varieties
The design of modern fuel filters involves the use of at least two levels of purification. The first stage is responsible for coarse filtration, which filters out large particles of debris. The second step is fine cleaning with the main filter. The cleaning element is installed between the engine and the fuel tank, and a coarse filtration system is mounted to the fuel pump in the main tank.
The type will depend on the vehicle's fuel system. There are only three modifications:
- Diesel;
- Carburetor;
- Injector.
Causes of breakdowns and signs of problems
The following symptoms indicate a problem:
- Unstable operation of the engine;
- Strong drop in engine power (no other problems with the unit);
- Increased fuel consumption.
Important! In a car built on an injection system, it is the coarse filter that suffers from poor fuel quality first of all.
Usually the problem does not appear immediately, but gradually. At first, the symptoms of a malfunction may be almost imperceptible, but over time they only increase.
The main cause of failure is low-quality fuel. Often its use leads not only to blockages, but sometimes to corrosion of the cleaning element. At first, the flow of the mixture through the hoses becomes difficult, and then the nozzles and other elements of the motor lose their efficiency.
Replacement for Renault Megane 2
The Renault Megan 2 fuel filter is part of the car's fuel system (the fuel filter is mounted separately on cars manufactured before 2006, to locate the part you need to look under the car). The manufacturer, according to the regulations, recommends replacing this element and the pump every 12,000 km. The original part costs 12 thousand rubles, analogues are cheaper.
In this case, a KL72 filter was used. It is smaller than the original, so I had to wrap electrical tape on top so that the parts fit snugly and were fixed. When replacing a Renault Megane 2 fuel filter, it is recommended to buy an original or a close analogue. Repairs are easiest to make in a pit or on a lift.
The Megan 2 fuel filter is attached with two green clips (2 on each side). It is important to pay attention to how the old part is installed (remember the direction of the arrows).
To replace the Megan 2 fuel filter, you just need to pull the element out of the mount and insert a new one. Do not forget about the direction of the arrows. Gasoline moves right through them. The line clamps are put on until they click.
Replacement for Megan 3
First, it is worth determining which system is used in the car (diesel or gasoline).
Diesel
The car is raised on a jack, the front right wheel is dismantled (for convenience, you can remove the headlight and fender liner). Using a wrench (10 millimeters), unscrew the bolt securing the filter.
Next, you need to disconnect the two fuel supply pipes, it is more convenient to do this from above, after removing the headlight. Unscrew the water sensor, then it is better to replace the 4 seals (they are round). The removed sensor must be replaced with a new filter (clean it from dirt and dust).
The new Megan 3 fuel filter is mounted in place, the hoses are connected, the fixing bolt is screwed in (the work will end only after pumping the fuel with a pear).
Petrol
Unfortunately, the quality of mixtures in Russia is worse than in Europe. This significantly reduces the life of the Renault Megan 3 fuel filter, which affects the performance of cars. This element is expensive, which is due to the pump built into the kit.
Filter replacement process:
- The target part is in the tank. It is necessary to dismantle the rear seats, then remove the plastic plug.
- The fuel hoses are disconnected (two in total), then a large plastic nut is unscrewed.
- It is important to thoroughly clean everything around the part so that excess dirt does not enter the tank.
- The flask is carefully pulled out of the tank, then you need to put it aside (it is not needed yet).
- A new fuel filter for Renault Megane is installed in the tank (do everything carefully, following the technique).
- The nut is tightened, the hoses are fixed (do not forget about the electrical input of the fuel pump).
- Plugs and rear seats are installed.
The Renault Megan 3 fuel filter replacement procedure is completed.
