Replacing the fuel filter on a Nissan Almera G15: where it is, how to change it and what mistakes to avoid

Fuel filter in Nissan Almera G15 (2013–2022) is a consumable that many owners forget to change before serious problems arise. Meanwhile, a dirty filter leads to loss of power, jerks during acceleration and even fuel pump failure. In this article we will look at where the filter is located on Almera with engines HR15DE (1.5 l) and HR16DE (1.6 l), how to replace it with your own hands, and why ignoring the regulations costs many times more.

Official regulations Nissan requires changing the fuel filter every 40,000 km or once every 2 years - whichever comes first. However, in Russian realities (low-quality fuel, dusty roads), it is better to reduce the interval to 30,000 km. If you notice that the car has become harder to start when cold or jerks when accelerating, the filter is long overdue for replacement.

Where is the fuel filter located on Nissan Almera G15

Unlike older models Nissan, where the filter was installed under the hood or under the bottom, in Almera G15 it is integrated into fuel module (fuel pump), which is located inside the gas tank. This is a typical solution for modern cars, but it complicates replacement: to get to the filter, you will have to dismantle the entire module.

The fuel module is located under the rear seat, under a hatch in the trunk floor. To see it:

• 🔧 Fold back the rear sofa (pull the hinges under the seat).
• 🔍 Find a square hatch measuring ~20x20 cm with the inscription FUEL PUMP or an arrow.
• 🔑 Unscrew the 4 bolts securing the hatch (usually a Phillips screwdriver or Torx T20).

Under the hatch you will see the top of the fuel module with the power connector and pipes. The filter itself is a mesh (coarse filter) and a paper element (fine filter), hidden inside the module. On some versions Almera the filter comes assembled with the pump, on others - as a separate removable part.

Signs of a clogged fuel filter

If the filter is clogged, the engine Almera begins to “starve” - it does not have enough fuel for normal operation. Symptoms appear gradually, but ignoring them is dangerous: over time, this leads to fuel pump failure (the cost of a new one is from 15,000 ₽). Look out for the following signs:

• ⚠️ Jerks during acceleration (especially at speeds of 60–90 km/h).
• ⚠️ RPM dips when you press the gas.
• ⚠️ Engine stalls at idle or it doesn't start well when hot.
• ⚠️ Increased fuel consumption (by 1–2 l/100 km for no apparent reason).
• ⚠️ Noise from the gas tank (the pump hums, trying to push fuel through the clogged filter).

In the later stages of contamination, the machine may won't start at all — the pump is not able to create the required pressure in the system. If you observe at least 2-3 symptoms from the list, the filter needs to be changed immediately.

⚠️ Attention: On Nissan Almera with engine HR16DE (1.6 l) a clogged filter more often leads to an error P0171 ("Lean mixture"). If the dashboard lights up Check Engine, check the filter first, not the sensors.

Which fuel filter to choose for Almera G15

On Almera G15 Two types of filters are installed:

1. Coarse mesh (original article number - 17040-JM00A). This is a fine mesh that protects the pump from large particles. It can be washed, but it is better to replace it.
2. Fine filter (original article number - 16400-JM00A). A paper element that traps small impurities. Comes assembled with the body or as a separate insert.

Original filters are expensive (from RUB 2,500 per set), but there are high-quality analogues:

Brand	Article	Type	Price, ₽	Notes
Nissan	16400-JM00A	Fine cleaning	2 800	Original, complete with case
Bosch	0 450 905 318	Fine cleaning	1 200	High-quality analogue, suitable for HR15DE/HR16DE
Mann	WK 512/2	Fine cleaning	1 500	High resource, services recommended
Japan Parts	FC-N164	Set (mesh + filter)	1 800	Good price/quality ratio

When purchasing, check whether the filter is suitable for your year of manufacture Almera. For example, on the 2013–2015 model. Sometimes modules with a different filter mount were installed. Also note flow direction (indicated by an arrow on the housing) - if you install the filter incorrectly, the pump will quickly fail.

Preparing for replacement: tools and safety precautions

To replace the fuel filter with Nissan Almera G15 you will need:

• 🔧 Set of screwdrivers (phillips, flat, torx T20).
• 🔨 Pliers or wrench for fuel pipe clamps.
• 🛠️ New filter (and/or mesh).
• 🧴 Carburetor cleaner or gasoline for flushing.
• 🧤 Rubber gloves (gasoline corrodes the skin).
• 🔥 Fire extinguisher (required! Gasoline is highly flammable).

Important: Replace with cold engine (preferably in the morning, when the car has been standing all night). Pressure is maintained in the fuel system even after the ignition is turned off - if you remove the pipes while “hot”, gasoline will spray out under pressure.

Drain the gasoline from the tank below the filter|Disconnect the battery terminal|Prepare a container for draining the fuel|Wear gloves and safety glasses|Provide ventilation (work outside or in a garage with the gate open)-->

⚠️ Attention: Do not smoke or use open flames near the machine during operation. Gasoline vapor is heavier than air and accumulates at the bottom - one spark is enough to ignite.

Step-by-step instructions for replacing the fuel filter

The process of replacing the filter Almera G15 takes 1.5–2 hours. Follow the instructions strictly step by step to avoid damaging the fuel module.

Step 1: Relieve fuel system pressure.

Open the hood, locate the fuse box (next to the battery) and remove the fuel pump fuse (Fuel Pump, usually 15A). Start the engine and let it run until it stalls. Repeat the start 2-3 times - this will relieve pressure in the system.

Step 2: Remove the fuel module.

Fold back the rear seat, unscrew the hatch and disconnect the pump power connector (press the latch and pull up). Next:

1. Disconnect the fuel pipes (press the plastic latches and slide the clamps).
2. Unscrew the module clamping ring (8 Torx bolts T20).
3. Carefully remove the module by tilting it so as not to bend the fuel level sensor float.

Step 3: Replace filters.

Disassemble the module: remove the bottom cover (usually with latches), remove the coarse mesh and fine filter. Wash the mesh in gasoline or replace it with a new one. The fine filter is replaced entirely - just remove the old one and install a new one, observing the direction of flow (the arrow on the body should point towards the pump).

Step 4: Reassemble everything in reverse order.

Place the module back into the tank, connect the tubes and the power connector. Don't forget to return the pump fuse! After assembly, turn on the ignition (do not start the car) for 5 seconds - the pump will pump gasoline into the system. Check for leaks.

What should I do if the car does not start after replacement?

If the engine does not start, check:

1) Are the fuel pipes connected (sometimes they fall off when installing the module).

2) Is the pump fuse inserted?

3) Is the module assembled correctly (the float should not block the pump).

If everything is in order, but the car does not start, relieve the pressure again and repeat the procedure.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing the fuel filter with Almera. Here are the most common of them:

• 🔧 Damage to the fuel level sensor float. When removing the module, it is easy to bend it - then the level readings on the device will be incorrect. Always hold the float with your hand.
• 🔧 Installing the filter backwards. If the direction of flow is reversed, the pump will overload and quickly burn out. Look at the arrow on the body!
• 🔧 Failure to maintain cleanliness. Dust or debris that gets into the tank clogs the new filter over several thousand km. Rinse the tank and use clean tools.
• 🔧 Ignoring the coarse mesh. Many people change only the paper filter and leave the old mesh. This reduces the life of the new filter by 2 times.

Critical error: using non-original filters without checking the article number. For example, a filter from Renault Logan looks similar, but has a different O-ring diameter. This leads to air leaks and an error P0172 ("Rich mixture").

⚠️ Attention: If, after replacing the filter, the dashboard lights up Check Engine, check the tightness of the tube connections. Air leaks are the most common cause of errors P0171 And P0172 after self-repair.

How much does a service replacement cost and when to contact professionals?

Cost of replacing a fuel filter Nissan Almera G15 in service depends on the region and level of the service station:

Service type	Cost of work, ₽	Cost of spare parts, ₽	Total, ₽
Official dealer	3 500–5 000	2 800–4 000	6 300–9 000
Unofficial service	1 500–2 500	1 200–2 000	2 700–4 500
On your own	0	1 200–2 800	1 200–2 800

It makes sense to contact the service if:

• 🔧 You have never worked with the fuel system.
• 🔧 The cause needs to be diagnosed Check Engine (for example, error P0190 — malfunction of the fuel pressure sensor).
• 🔧 The entire fuel module needs to be replaced (the cost of a new one is from 15,000 ₽).

In other cases, you can replace the filter yourself. The main thing is not to rush and follow the instructions. If you are afraid of damaging the module, practice disassembling it or watch a video with replacement Almera G15 (for example, on YouTube on request Nissan Almera fuel filter replacement).

Frequently asked questions (FAQ)

Is it possible to wash the fuel filter instead of replacing it?

The coarse mesh can be washed (with gasoline or carburetor cleaner), but the fine paper filter cannot be washed. Its pores become clogged with small particles that cannot be removed without destroying the material. Flushing will give a temporary effect, but after 500–1000 km the problems will return.

How often do I need to change the filter if I fill up at trusted gas stations?

Even at fuel stations with a good reputation (for example, Lukoil or Gazpromneft) there are impurities in gasoline. Optimal interval for Almera G15 — every 30,000 km or once every 2 years. If you drive a little (less than 10,000 km/year), the filter still ages - the rubber seals lose their elasticity, and dirt begins to seep through them.

What happens if you don't change the fuel filter?

The consequences depend on the degree of pollution:

• At the initial stage - loss of power (the car accelerates worse).
• Next - fuel pump damage (it works overload, trying to push gasoline through a clogged filter).
• At the final stage - injector failure (dirt gets into the injection system and they have to be cleaned or replaced).

The cost of repairs in this case exceeds 20,000 ₽ (pump + injectors + diagnostics).

Is the Renault filter suitable for Nissan Almera?

No, it doesn't fit. Although Almera G15 And Renault Logan/Sandero built on the same platform, their fuel modules are different. The filters are different:

• O-ring diameter.
• Location of fastening latches.
• The shape of the body (at Renault it is more elongated).

Installing a non-original filter will lead to air leaks and engine operation errors.

Do I need to reset the ECU adaptations after replacing the filter?

On Nissan Almera G15 It is not necessary to reset the adaptations - the electronic control unit (ECU) will automatically adapt to the new filter resistance after 2-3 engine starting cycles. However, if you notice that the car jerks during acceleration, you can reset the adaptations manually through the diagnostic scanner (for example, ELM327) or by disconnecting the battery terminal for 10 minutes.
