Fuel filter on Nissan Almera G15: where is it located and how to replace it

Nissan Almera G15 (2012–2019) is a popular sedan known for its reliability and ease of maintenance. However, even such an unpretentious car has components that require regular attention. One of them is fuel filter - a part on the condition of which the stability of the engine, fuel consumption and acceleration dynamics directly depend.

Many owners Almera G15 are faced with the question: where exactly is the fine fuel filter located? Unlike older Nissan models, where the filter was often installed under the hood or along the fuel line, G15 the manufacturer chose a different solution. This causes confusion, especially for those who are used to the classic layout. In this article we will not only show exact location of the filter (with photos and diagrams), but we’ll also tell you how to check it, when to change it, and what nuances to consider when replacing it.

Almera G15 fuel system design: where to look for a filter?

B Nissan Almera G15 (body N17) the fuel filter is integrated into fuel module, which is located directly in the gas tank. This is a typical solution for modern cars, where manufacturers strive to reduce the number of individual elements under the hood. This approach has advantages (compactness, lower risk of leaks) and disadvantages (difficulty of replacement).

Fuel module Almera G15 includes:

• 🔋 Gasoline pump (submersible, electric)
• 🧹 Coarse filter (mesh at the pump inlet)
• 🔍 Fine filter (this is what is most often meant by the “fuel filter”)
• 📏 Fuel level sensor

It is important to understand that There is no separate removable filter under the hood or on the fuel line in the Almera G15. This means that to replace the fine filter you will need to remove the entire module from the tank. The procedure is not the simplest, but can be done in a garage if you have the tools.

Where exactly is the fuel filter: photo and diagram

Fine filter in Almera G15 located inside the fuel module, which is attached to the gas tank under the rear seat. To get to it you need to:

1. Remove the rear seat cushion (it is secured with latches).
2. Open the access hatch to the fuel module (plastic cover with the inscription FUEL PUMP).
3. Disconnect the connectors and fuel hoses, then remove the module.

The photo below shows the fuel module Almera G15 in disassembled form. The fine filter is indicated by a red circle:

Externally, the filter is a cylindrical element made of plastic or metal (depending on the manufacturer), fixed to the module body. In some versions of the modules, the filter may be non-separable, which means that the entire assembly must be replaced.

How to distinguish a coarse filter from a fine one?

The coarse filter is a mesh at the inlet of the fuel pump (fine metal mesh). A fine filter is a separate unit, usually white or black, with a paper filter element inside.

When to change the fuel filter: signs and regulations

Manufacturer Nissan does not establish strict regulations for replacing the fuel filter for Almera G15. The official manual states that the filter is designed for the entire service life of the vehicle. However, in practice this is far from the case. Russian realities (low-quality fuel, dust, condensation in the tank) reduce the filter life to 30–50 thousand km.

The main signs of a clogged filter:

• ⚡ Jerks during acceleration (especially at high speeds)
• 🛢️ Increased fuel consumption (10–15% higher than usual)
• 🚗 Power loss when pressing the gas pedal
• 🔥 Difficulty starting the engine (especially when cold)
• 💨 Extraneous noise from the gas tank (pump hum)

If you notice at least 2-3 symptoms from the list, the probability of a clogged filter is 80%. For accurate diagnosis, you can measure fuel rail pressure (norm for Almera G15 — 3.5–4.0 bar). If the pressure is lower 3.0 bar, the filter or pump is faulty.

Step-by-step instructions: how to replace the fuel filter on Almera G15

Replacing the filter requires care and compliance with safety precautions. Need to work on a cold engine (to avoid high pressure in the system) and in a well-ventilated area (gasoline vapors are toxic).

Required tools:

• 🔧 Set of sockets and wrench for "10"
• ⚒️ Flat-head screwdriver (for removing the hatch)
• 🧰 Pliers (for hose clamps)
• 🧴 Sealant for fuel systems (for example, Loctite 577)
• 🧻 Rags and container for draining gasoline

Step by step process:

1. Relieve system pressure. To do this, remove the fuel pump fuse (located in the mounting block under the hood, marked FUEL PUMP) and start the engine. Let it die out.
2. Remove the back seat. The pillow is attached with latches - pull it up with force.
3. Unscrew the access hatch to the fuel module (4 bolts under the head "10").
4. Disconnect the power connector and fuel hoses (pre-wrap them with rags to avoid spilling gasoline).
5. Remove the fuel module. To do this, turn it counterclockwise and carefully pull it out, tilting it so as not to damage the level sensor float.
6. Disassemble the module and replace the fine filter (or the entire module if the filter is non-separable).
7. Reassemble everything in reverse order, not forgetting to check the tightness of the connections.

⚠️ Attention: When removing the module, do not pull on the fuel hoses - they may burst. Use a special puller or carefully pry the fasteners with a flat-head screwdriver.

Which filter to choose: original vs analogues

For Nissan Almera G15 The original fuel filter is supplied only assembled with the module (article no. 17040-JM00A). Its price ranges from 8,000 to 12,000 rubles, which makes replacement quite expensive. However, there are more budget-friendly alternatives:

Manufacturer	Article	Type	Price, rub.	Notes
Nissan	17040-JM00A	Module assembly	8 000–12 000	Original, 1 year warranty
Bosch	0 986 580 959	Filter separately	1 200–1 500	Suitable for dismountable modules
SCT	ST 393	Module assembly	4 500–5 500	Good price/quality ratio
Japan Parts	JF0101	Filter separately	800–1 000	Budget option, resource ~40 thousand km

If you decide to save money and buy only a filter (without a module), make sure that your fuel module collapsible. In some versions Almera G15 The filter is welded to the housing and cannot be replaced separately.

⚠️ Attention: When purchasing analogues, pay attention to filter capacity. Cheap counterfeits may have a smaller filtration area, which will lead to rapid clogging and breakdown of the fuel pump.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes when working with the fuel system. Almera G15. Here are the most common of them:

• 🔥 Ignoring pressure release. If you do not relieve the pressure before removing the hoses, gasoline will spray out under high pressure, which can result in a fire or fuel getting into your eyes.
• 🔧 Damage to the level sensor float. When removing the module, many people forget that the float is fragile and can break if moved carelessly.
• 🧴 Saving on sealant. If you do not treat the module O-ring with sealant, gasoline will leak over time.
• 🔄 Incorrect module assembly. If the filter is installed crookedly or the clamps are not fully latched, the pump will work with overload.

To avoid problems, follow a simple rule: take photographs of each stage of disassembly. This will help you assemble the module in the correct sequence. It would also be a good idea to check the operation of the pump after installation - turn on the ignition (without starting the engine) and listen: you should hear a uniform hum of the pump for 2-3 seconds.

FAQ: Frequently asked questions about the Almera G15 fuel filter

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

Technically, flushing is possible, but not recommended. After washing, the paper filter element loses its properties, and small particles of dirt will penetrate the system. It is better to replace the filter with a new one.

What happens if you don't change the filter at all?

A clogged filter leads to:

• 🔥 Overheating and failure of the fuel pump (the cost of a new one is from 5,000 rubles).
• 🛢️ Increased fuel consumption (up to 20% above normal).
• 🚗 Loss of power and jerking when moving.
• 💥 Risk of injector breakdown (cleaning them will cost 3,000–6,000 rubles).

Is it possible to replace the filter yourself without a pit or lift?

Yes, no lift needed. It is enough to remove the rear seat - the access hatch to the fuel module is located directly under it. The main thing is to provide good lighting and ventilation.

Which fuel pump is better to choose when replacing a module?

• SCT ST 393 — the best option in terms of price/quality.
• Denso 953-0101 - reliable, but expensive (from 7,000 rubles).
• Japan Parts JF0101 - budget, but less resource.

Avoid cheap Chinese modules without a brand - they often fail after 10-15 thousand km.
