The fuel filter in the Nissan Almera Classic, as in any vehicle, is one of the main components of the fuel supply system. Its regular maintenance and replacement are a prerequisite for maintaining the car in good condition.

Where is the fuel filter located?

Fuel pumps on Nissan Almera Classic cars are located in a special removable module inside the fuel tank. These machines use a two-stage gasoline purification system.

It consists of two filters:

• the first one is intended for rough cleaning of fuel and is located at the inlet of the fuel intake module;
• the second - fine cleaning - is installed on the upper part of the fuel pump housing.

The location of the fuel filters and pump on the Nissan Almera H16 is absolutely identical to the location of these devices in the Nissan Almera Classic.

Layout of filters in the fuel pump module

The Almera G15 model is equipped with a simplified fuel filtration system, consisting of only one device for coarse cleaning.

Replacement frequency

The manufacturer does not indicate the service life of the filter in the service manual for the vehicle. According to official Nissan documentation, its replacement is carried out only together with the installation of a new fuel pump. But car owners, given the unstable quality of gasoline in Russia, try to change filters every 90 thousand kilometers. Some car enthusiasts perform this procedure much more often - after 12–15 thousand km.

Sometimes there is a need to urgently replace the filtration device. Its signs may include dips and jerks during engine operation, especially when accelerating over 80 km/h. Engine “tripleting” may occur in different speed ranges.

How often to change

The frequency of replacing the fuel filter on Nissan Almera N16 and Classic is not established by the manufacturer. The latter determines the timing at which it is necessary to install a new pump. As a result, the owners of the Japanese model had to empirically determine the frequency of this procedure.

According to the results obtained, in real operating conditions of the Nissan Classic, the fuel filter needs to be changed every 90 thousand kilometers. However, this parameter is not absolute. A number of motorists carry out the procedure after 12-15 thousand kilometers. This frequency is mainly due to the use of low-quality gasoline, which quickly clogs the coarse and fine filters.

This procedure should also be carried out if:

• failures in engine operation occur;
• the engine picks up speed jerkily (especially at speeds above 80 km/h);
• signs of tripping appear at different speeds.

Each of the above phenomena indicates that low-quality fuel is entering the engine.

And this may indicate problems with the filter elements.

Selecting a filter

Original fuel filters for Nissan are not available for sale separately. They can be purchased and replaced only as an assembly with a fuel pump. The part number for ordering the product is 17040–95F0B.

Analogs

As an analogue of the original filter mechanism for the fuel system of Nissan cars, they use devices from other automakers. Most often, a coarse filter from the Hyundai Accent (product code 31090–25000) or the domestic VAZ 2110–12 is used for this purpose. These parts, unlike the original, have a different shape for the installation part, which will have to be trimmed a little. From original spare parts, you will need a rubber ring to seal the module cover (17342–95F0A). Usually it has to be changed after damage due to careless dismantling of the cover.

The choice of fine filters is a little richer - this is the original part from Accent (article 31911–25000) or its SCT analogue with the number ST 399. These devices differ from the original Nissan filters in the location of the mounting point of the fuel pressure regulator. When installing them, you need to slightly trim the plastic body of the cup where the fuel pump is located. The installation of such elements has been repeatedly tested on Nissan cars produced in 2006, 2007 and 2008. For the Almera G15, the suitable filter is Francecar FCR 210141, which was successfully tested on a 2014 model.

Replacement procedure: step-by-step instructions

Before performing operations, you need to prepare the following tools:

• set of wrenches;
• spanning tool (gas wrench);
• wire cutters, pliers;
• a set of screwdrivers with different tips;
• rust removers (solvent, carb cleaner);
• an empty 1-liter container for draining remaining gasoline from fuel lines;
• clean rag.

Work on removing elements must be carried out strictly sequentially. First you need to relieve the pressure in the car's fuel system. The fuse responsible for the operation of the pump must be removed from the mounting block under the instrument panel in the car interior. In the diagram it is marked as fuel pump.

The sequence of actions is as follows:

1. Pull out the fuse.
2. Then start the engine.
3. Open the oil filler cap.
4. Wait until the engine stops on its own.

The procedure must be repeated 2 more times with an interval of 1 minute.

Further actions are carried out inside the car. Need to:

1. Raise the rear seat of the car.
2. Find the hatch containing the fuel module.
3. Wipe thoroughly around the nest cover so that no dirt or dust remains (otherwise, when opening it, it will get inside, and this is undesirable).
4. Unscrew the cover fasteners using a screwdriver or wrench.
5. Disconnect the pump by removing the power connector.
6. Start the engine and wait until it stops.
7. Pressing the latches, sharply pull out the gasoline supply hose.
8. Wait until the remaining gasoline flows out of the line.

To prevent fuel from spilling and staining everything around - the smell of gasoline may not disappear from the car for a long time - you need to place an empty container near the module (a white plastic case with a lid-rim around the circumference) and lower the fuel supply hose into it.

Now we move on to the stage of removing the module. Need to:

1. Unscrew the locking ring of the module using a socket tool.
2. Remove the fuel module, working carefully. The fact is that at the bottom of the device there is a float for the gasoline level sensor. If you rush, it can be easily damaged.

Next, work is carried out to disassemble the module:

1. Remove the top cover by bending the petal-type clamps. To do this, use a flat-tip screwdriver.
2. Disconnect the connectors from the regulator (level sensor). Sometimes the wiring can be pulled together with a rigid scraper. It needs to be cut off with wire cutters or pliers.
3. Press 3 clamps at once to pull up the fuel pump with both filters from the plastic housing of the module.
4. Disconnect the pressure sensor - it is easy to pull out, since it is held on a clamp.
5. Thoroughly clean the interior of the case using a cloth. It is recommended to soak the tip in acetone or gasoline.

The pump should be thoroughly inspected for damage. The coarse filter is located at the bottom of the device; the mesh is simply removed by hand. But the fine cleaning element is attached using plastic clips. They should be carefully pressed with a flat screwdriver so that the filter is released and comes out.

Next, reassembly into the tank is carried out. A new original Nissan fuel module is installed (approximate price - 15 thousand rubles) or a filter from a third-party manufacturer

It is important not to forget to replace the original cuffs of the fittings

How to change it yourself?

Sometimes car owners turn to an official dealer to replace Nissan Almera Classic fuel filters. But more often than not, many people prefer to do this work themselves.

Preparation

Before replacing the fuel filter, you need to prepare tools and auxiliary materials.

A short list of what you need:

• wrench 10;
• gas key;
• a screwdriver with a narrow flat and cross-shaped blade;
• cleaning agent (acetone, solvent or carburetor cleaner);
• an empty, stable container with a volume of 0.5–1.0 liters for draining remaining gasoline from the main line;
• rags for collecting spilled fuel.

Stages of work

After preparing the tool, you can begin work on removing and replacing parts.

Step by step sequence:

1. It is necessary to relieve pressure in the fuel system. To do this, you need to find the pump fuse in the mounting block, which is located under the instrument panel in the area of ​​the driver’s left foot. It is marked on the diagram on the block cover as “fuel pump”. You should remove it from the socket. Then you need to start the car engine. It will run for a short time and then die. It is advisable to repeat this procedure several times with an interval of about a minute between starts. While the engine is running, open the filler neck of the gas tank to equalize the pressure with atmospheric pressure.
2. Fold back the rear seat cushion, under which the tank is located. It has a mounting socket in which the fuel module is installed. Before removing the cover, it is advisable to wipe off dust and dirt around the socket. Using a 10 mm wrench or a Phillips screwdriver, you need to unscrew the three bolts securing the cover. Underneath there will be a cylindrical module made of white plastic with a black ring around its circumference.
3. If the fuel pressure has not been relieved using the method described above, it can be lowered with the pump power connector disconnected. The procedure for starting the engine is similar. Then you need to install a container next to the drain module. By pressing the clamping ring, you need to pull off the fuel supply hose, previously wrapped in rags, and quickly throw it into the container. It is important not to spill fuel on the interior components, since gasoline will evaporate from them for a very long time. Up to 0.2–0.3 liters of fuel can leak from the line.
4. Next, you should unscrew the module cover, which is secured with a ring nut (a black ring with protrusions around the perimeter of the module). The nut is tightened quite tightly and access to it is inconvenient. To unscrew, use the handles of a gas wrench. Now you can get the fuel pump module assembled with filters. In this case, it is important not to damage the float of the fuel level meter installed in the lower part of the device.
5. You need to remove the top cover of the module by bending the three blade clamps with a flat screwdriver, and disconnect the connectors from the fuel level sensor and pump. Sometimes the wires may be held together with a nylon tie that needs to be cut off.
6. After disconnecting the connectors, you can remove the pump with filters from the module housing. It is secured with three clamps that must be pressed while simultaneously pulling out the pump. The pressure regulator is located on the clamp and can be removed very easily. Then you need to clean the plastic cup of the module from the dirt accumulated inside.
7. Next, an external inspection of the pump is carried out, as well as repair and maintenance of structural elements. The coarse filter is located on the bottom of the mechanism and can be easily removed by hand. The fine cleaning device is located at the top of the pump and is secured with two plastic clips. To bend them, use the tip of a flat screwdriver. When dismantling the filters, it is important not to forget to remove the cuffs from the pump fittings, which are installed in the new cleaning mechanisms.
8. Then you can change the filtration devices and begin assembly in reverse order. In this case, you need to modify the pressure regulator valve by cutting its tube and extending it with an insert from a gas-resistant hose.

You can watch the procedure for replacing fuel filters in a video from user Azat Alikberov.

Removing the fuel pump

First you need to remove the rear seat element. The gasoline pressure must be relieved in the fuel line. The fuse box, which is located under the dashboard on the driver's left side, must be open. Usually on the top (cover) there is a designation with which this fuse is easy to find, because it is marked FUEL PUMP. It should be in the 2nd column (4th from the top), and also have the designation 15A. The fuse must be removed from its socket. Start the car, and after 3-5 seconds the engine will stall on its own. This action must be repeated until the engine no longer starts (usually this works after 3-5 attempts). Then wait a minute and repeat the action. If everything is done correctly, then the pressure will actually be released to the maximum, in other words, to the end.

In this case, if you do not want to look for the fuse, you should disconnect the connectors from the flange (located under the seat) of the fuel tank. There is no need to remove the hoses right away.

It is necessary to remove the filler cap and then relieve the internal pressure in the gas tank. We unscrew three dark-colored plastic bolts and remove the hole cover for inspection. Afterwards, the large plastic nut must be unscrewed by hand. We should be able to see a snow-white glass, in the place of which the gas pump is installed. This is a cylinder measuring 10 by 3 centimeters. Some models have an internal mesh, which is usually yellow with dirt.

HOW TO REPLACE THE FUEL PUMP FOR A NISSAN ALMERA CLASSIC?

Replacing the fuel pump on Almeria

They cleaned the gas receiver and changed the pump, but did not change the filter. And the speed rose, but the start-up was not very good.

The return hose must be removed by accurately pressing the plastic latch. This hose extends from the beginning of the engine, as well as an arrow that is directed to the fuel pump. With a little pressure, approximately one small glass of gasoline will flow out of the hose. The second hose will also need to be disconnected, but nothing will leak out. The most important thing is that you need to be careful so that they are not damaged when removing them.

The connector with the harness must be removed and the fuel level meter, that is, the float located in the tank, disconnected. And then you need to remove the fuel pump itself.

Now you can start cleaning the fuel pump itself.

Price issue

The cost of replacing the fuel filter on Nissan Almera Classic and N16 yourself can vary and depends on the manufacturer of spare parts. The price of the original pump complete with filters is about 10 thousand rubles.

The cost of non-original filters is much lower - for the entire set of parts you will have to pay about 1,700 rubles when using Hyundai devices, or about 800 rubles. for cheaper analogues. The most economical option is to replace the filter on a Nissan G15 - its price is around 120 rubles.

If you don’t change it, what are the consequences?

A car consumes a lot of fuel over its entire service life. At around 100 thousand km, about 10,000 liters of fuel passes through the fuel system. Even the cleanest gasoline contains impurities and dirt, which are successfully retained by filters. Therefore, Nissan Almera Classic and other foreign cars use a two-level filtration system, which is much more efficient and lasts longer.

However, the mileage takes its toll. Over time, the filters themselves become clogged. The first symptoms of a poorly functioning filtration system are known to experienced car enthusiasts:

• engine loss of traction;
• work intermittently;
• increased fuel consumption (the pressure in the fuel system does not correspond to the nominal value);
• difficult startup (up to complete failure).

First, this leads to damage to the pump, since clogged filters cause disruptions in liquid pressure. Several such failures - and the mechanism stops pumping gasoline, the impeller rotates freely on the shaft. Almera Classic or N16 has a submersible fuel pump. It receives cooling by pumping fuel. No fluid flow - no cooling.

If dirt gets inside the injector, the result is even worse. The owner has to repair the entire fuel system, including the intake manifold and injectors. The latter, as is known, operate synchronously on the Almere Classic with distributed injection - in accordance with the valve timing (the electronic control unit receives signals from the phase sensor). The system reacts instantly to clogging of at least one of the injection elements. The engine stops starting and fuel consumption increases.

If you have the described symptoms, it is better not to hesitate. Contact DDCAR car service to replace the fuel filter. Our craftsmen will do this work for only 600 rubles. You can wait for the work to be completed in a cozy relaxation area with Wi-Fi.

Consequences of untimely replacement

If the fuel filters are not replaced in a timely manner, at best, the car simply will not start, since the pump will not be able to supply gasoline to the injectors in the required quantity. In this case, there is a risk of pump failure, since it is fully cooled and lubricated only when pumping fuel. In the worst case scenario, small particles of dirt will travel along the fuel lines to the injection system injectors and clog them. Sometimes this clog can be so severe that it cannot be cleared. In this case, the parts must be replaced.
