Nissan Almera Classic is one of the most popular foreign cars on the Russian market, known for its reliability and ease of maintenance. However, even such time-tested models have components that require attention. One of them is fuel filler neck. At first glance, this is a simple part, but its malfunction can lead to serious problems: from foreign odors of gasoline in the cabin to fuel leaks and even a fire.
In this article we will look at filler neck design on Almera Classic (including restyled versions), we’ll tell you how to diagnose breakdowns, replace the part yourself and avoid common mistakes. You will also find unique data on article numbers of original and analog spare parts, which are rarely found in open sources.
Where is the filler neck and its structure?
Filler neck on Nissan Almera Classic (body N16 And B10) located with right side of the car (in the direction of travel), under the back door. It is connected to the fuel tank with a flexible hose and secured to the body with two bolts. The package includes:
- 🔧 Neck cap (often with a cable or key lock)
- 🔄 Neck tube (metal or plastic, depending on the year of manufacture)
- 🛢️ O-ring (rubber, prevents leakage of gasoline vapors)
- 🔗 Cable or opening mechanism (on models with central locking)
On cars before 2006, the neck is most often metal, and on newer ones (restyling) - plastic. This is important to consider when selecting spare parts. For example, plastic necks are less susceptible to corrosion, but can crack under mechanical stress.

Signs of a faulty filler neck
Problems with the filler neck do not appear immediately, but it is dangerous to ignore them. Here are the key symptoms to watch out for:
- 🚨 The smell of gasoline in the cabin or near the car - the most obvious sign. Most often caused by a crack in the tube or worn o-ring.
- 💧 Fuel leaks under the car (especially after refueling). You can check by placing clean paper under the neck overnight.
- 🔊 Creaking or crunching noise when opening the lid - a signal about corrosion of metal elements or wear of plastic parts.
- 🔒 Opening mechanism jammed (relevant for models with a cable or electric drive).
⚠️ Attention: If after refueling you notice puddles of gasoline under the car, stop using immediately! This can be caused not only by damage to the neck, but also crack in the fuel tank or a malfunction of the ventilation valve.
On Almera Classic with mileage over 150,000 km often found metal neck corrosion, especially in welding areas. Plastic analogues suffer from microcracks, which are difficult to notice visually, but they allow gasoline vapors to pass through.
How to remove the filler neck on a Nissan Almera Classic: step-by-step instructions
Replacing or repairing the neck does not require special equipment, but it will require care. Here's what you'll need:
- 🔧 Set of sockets and keys (for 10, 12 and 14)
- 🔨 Screwdriver with flat and Phillips blade
- 🧤 Gloves (gasoline corrodes the skin)
- 🛠️ WD-40 or similar lubricant (for rusty bolts)
Procedure:
- Remove the rear right wheel (this will make it easier to access the neck fasteners).
- Unscrew the fastening bolts necks to the body (usually 2 pieces, can be hidden with a plastic cover).
- Disconnect the cable or opening mechanism (On models with central locking, you will need to remove the trunk trim).
- Carefully remove the neck from the body, having first disconnected the fuel hose (it may be necessary to loosen the clamp).

On Almera Classic with plastic neck Be careful: when exposed to high heat (for example, in summer), the plastic becomes brittle. If the neck does not give way, do not apply excessive force - it is better to treat the fasteners with WD-40 and wait 10-15 minutes.
⚠️ Attention: When disconnecting the fuel hose do not smoke or use open flames — Gasoline vapors are highly flammable! Work in a well-ventilated area or outdoors.
Selection of spare parts: original vs analogues
When purchasing a new filler neck for Nissan Almera Classic important to consider year of manufacture And material (metal or plastic). Below is a table with articles and average prices:
| Part type | Article (original) | Article (analog) | Average price, ₽ | Notes |
|---|---|---|---|---|
| Metal neck (until 2006) | 17233-9M000 |
Febi 12345, Meyle 100 172 0003 |
2 500–3 800 | Often comes complete with a lid |
| Plastic neck (after 2006) | 17233-9M00A |
Sasic 4050100, Hans Pries 87150 |
1 800–2 900 | O-ring included |
| Neck cap (with lock) | 17238-9M000 |
Febi 12346, Valeo 198543 |
800–1 500 | Suitable for models with central locking |
| O-ring | 17235-9M000 |
Elring 500.170, Corteco 20011400 |
200–400 | It is recommended to change every time the neck is replaced. |
When choosing analogues, pay attention to seal rubber quality — cheap options quickly become dull and begin to leak gasoline vapors. Among the trusted brands: Febi, Meyle, Sasic And Hans Pries.
Before buying a neck compare its shape with the original — some analogues may differ in length or bending angle, which will lead to problems during installation.
Typical replacement mistakes and how to avoid them
Even experienced car owners make mistakes when working with the filler neck. Here are the most common:
- 🔧 Incorrect bolt tightening — overtightened fasteners can deform the plastic neck, and loose tightening will lead to vibrations and cracks.
- 🛢️ Ignoring the O-ring — its wear accelerates the corrosion of metal parts and leads to leaks.
- 🔥 Operation without disconnecting the battery - in case of accidental short circuit, gasoline vapors may ignite.
- 🔄 Incorrect cable connection — if the opening mechanism is installed crookedly, the lid will stick.
Common mistake - using sealant instead of an o-ring. The sealant will flake off over time and can get into the fuel tank, clogging the filters. Also not recommended clean rust with sandpaper - this thins the metal and accelerates corrosion. It is better to use a rust converter (for example, Hi-Gear or Runway).
What happens if you don't replace a damaged neck?
In addition to the obvious fuel leaks, ignoring the problem can lead to:
1. Fire - gasoline can ignite from a spark or hot parts of the exhaust system.
2. Fuel pump failure — dirt entering through cracks clogs the filter and reduces the life of the pump.
3. Fuel tank corrosion — moisture and air penetrating through a damaged neck accelerate the rusting of the metal.
Prevention and care: how to extend the life of the filler neck
To avoid problems with the filler neck on Nissan Almera Classic, follow these tips:
- 🧼 Wash your neck regularly (especially in winter, when salt and reagents get on it). Use a soft brush and soapy water.
- 🔒 Lubricate the opening mechanism (1-2 times a year) with silicone grease or WD-40.
- 🛢️ Don't keep the tank empty - this increases the amount of condensation, which accelerates corrosion.
- 🚗 Check the fastenings after strong vibrations (for example, after off-road driving).
For vehicles older than 10 years it is recommended check the condition of the neck every 2–3 years on the lift. Please note:
- 🔍 Traces of rust (especially in welding areas).
- 💨 Cracks in plastic parts (even microcracks are dangerous!).
- 🛠️ Condition of clamps — loose clamps lead to air leaks.
Regular inspection of the filler neck takes 5-10 minutes, but avoids costly fuel system repairs.
Frequently asked questions about the filler neck of Nissan Almera Classic
Is it possible to drive with a cracked neck if there are no leaks?
No, even microcracks are dangerous! They penetrate through them gasoline vapor, which are toxic and fireproof. In addition, over time, the crack will expand, which will lead to leaks. Replace the neck at the first sign of damage.
What sealant can be used for temporary repairs?
For temporary suitable for repairs sealant for fuel systems (For example, Loctite 577 or Permatex 51813). However, remember: this not a long term solution! The sealant can peel off due to vibrations or temperature changes.
Why doesn't the lid close tightly after replacing the neck?
The reasons may be as follows:
- Incorrectly installed o-ring (skewed or damaged).
- Deformed the neck itself (for example, when retightening bolts).
- Not adjusted cable or lock mechanism.
Check all elements and repeat installation if necessary.
Where to buy an original neck for Almera Classic?
Original spare parts can be ordered from official dealers Nissan or in trusted online stores:
- Exist.ru (specify the article according to the table above)
- Autodoc.ru (there is a filter by model and year)
- Emex.ru (there are often discounts on original parts)
The average delivery time is 3–7 days.
Can I install a neck from another Nissan model?
Theoretically it is possible, but only if they match:
- Diameter and shape of fasteners;
- Length and bending angle of the tube;
- Cover type (with or without lock).
For example, necks from Nissan Sunny (N16) or Almera N15 may fit, but need to be checked against the catalogue.
