Fuel filter <em>Nissan Murano Z51</em>: how to choose, where it is located and how to replace it yourself

Fuel system Nissan Murano Z51 (2008–2014) - one of the key components on which the stability of the engine depends VQ35DE or VQ25DE. Fuel filter in this model it often becomes a “weak link”, especially after 100,000 km. Its clogging leads to jerks during acceleration, difficult starting and increased fuel consumption - symptoms that owners often attribute to a malfunction of the injectors or fuel pump.

Unlike many modern crossovers, where the filter is integrated into the fuel module, Murano Z51 it is placed separately - this simplifies replacement, but requires knowledge of the nuances. In the article we will look at which filter to choose (original vs analogues), where is it located under the hood, how often to change in Russian conditions and how to avoid common mistakes with self-replacement. We will also provide current articles, prices and step-by-step instructions with photos.

Where is the fuel filter located in Nissan Murano Z51

B Murano Z51 fuel filter installed under the hood, next to the right shock absorber strut (passenger side). This is a typical place for models Nissan that period - the same filter can be found, for example, in X-Trail T31 or Pathfinder R51.

Specific location:

• 🔧 To the right of the engine, if you look in the direction of travel.
• 📍 Next to vacuum brake booster And adsorber.
• 🔌 Two fuel lines (supply and return) and an electrical connector for the pressure sensor (on some versions) are suitable for the filter.

The photo below shows the filter on the engine VQ35DE (3.5 l): its body is black, with metal fittings and plastic fastening to the body. Access to it is open, but for ease of replacement it is recommended to remove air filter or move the pipes to the side.

Important! On some versions Murano Z51 for the American market, the filter can be integrated into the fuel pump (in the tank). This applies to models with the system Returnless (without return line). To accurately determine the type of system, check for the presence of a second fuel pipe under the hood:

• ✅ Two tubes → filter under the hood.
• ❌ One tube → filter in the tank (module replacement required).

When to change the fuel filter: regulations and signs of clogging

Official regulations Nissan for Murano Z51 includes replacing the fuel filter every 60,000 km. However, in Russian realities this interval should be reduced to 40,000–50,000 km, especially if:

• ⛽ You refuel at questionable gas stations (risk of dirt and water).
• 🌡️ You operate the car in conditions of sudden temperature changes (condensation in the tank).
• 🚗 Often drive on dusty roads or off-road.

Signs that the filter is clogged and requires replacement:

• 🔥 Dips during acceleration (especially at high speeds).
• 🔄 The engine stalls at idle or when suddenly releasing gas.
• ⚡ Increased fuel consumption by 1–2 liters for no apparent reason.
• 🔊 Noisy fuel pump (buzzes louder than usual due to increased load).

A critical mistake many owners make is to ignore replacing the filter until the “Check Engine” appears. By this point, the filter may already be so clogged that the fuel pump wears out, and the pressure in the system drops below normal (less than 3 bar).

Which fuel filter to choose: original vs analogues

For Nissan Murano Z51 Filters with article number are suitable 16400-4M000 (original) or its analogues. Below is a table with proven options, their catalog numbers and average prices for 2026:

Manufacturer	Article	Price, ₽	Notes
Nissan (original)	16400-4M000	2 800–3 500	Quality is guaranteed, but often counterfeited.
Bosch	0 450 905 979	1 200–1 500	Good filtration, but the body is thinner than the original.
Mann	WK 512	1 400–1 700	Optimal price/quality balance.
Mahle	KL 83	1 300–1 600	Suitable for severe operating conditions.
JS Asakashi	FS20007	800–1 000	Budget option, but the resource is lower.

When choosing an analogue, pay attention to:

• 🔄 Fuel flow direction (indicated by an arrow on the body).
• 🔧 Connection diameter - must match the original (10 mm).
• 📏 Dimensions: length ~15 cm, diameter ~6 cm.

How to distinguish an original filter from a fake?

On the original filter Nissan should be:

1. Clear labeling 16400-4M000 with laser engraving.

2. Logo Nissan on the body (not a sticker!).

3. Metal fittings with anti-corrosion coating.

4. Packaging with a hologram and barcode, which can be checked on the manufacturer’s website.

If you are exploiting Murano Z51 on gas (gas), it is recommended to install a filter with enhanced filtration (for example, Mann WK 512) and reduce the replacement interval to 30,000 km — gas dries out the fuel system, and the risk of clogging is higher.

Step-by-step instructions for replacing the fuel filter

Replacing the filter with Murano Z51 does not require special tools, but will be required relieve pressure in the fuel systemto avoid gasoline spills. To work you will need:

• 🔧 10 mm wrench (for attaching the filter).
• 🔨 Flat screwdriver (for removing clamps).
• 🧤 Gloves and rags (gasoline is aggressive to the skin).
• 🔥 Fire extinguisher (in case of fuel leak).

Step 1: Relieve Pressure

Open the hood and find fuse box (near the battery). Remove the fuse Fuel Pump (usually 15A, number F10 or F11 - check the diagram on the block cover). Start the engine and let it run until it stops (it will burn out the remaining fuel in the system). After this, turn the starter 2-3 more times to make sure there is no pressure.

Step 2. Removing the old filter

Disconnect the fuel hoses by pressing the clamps (they are plastic and break if handled roughly!). Remove the filter mounting to the body (10 mm bolt). Be prepared for some gasoline to leak out of the hoses - place a container.

Step 3: Install a new filter

Transfer the mount from the old filter to the new one. Install a filter arrow in the direction of fuel flow (from tank to engine!). Connect the hoses until the latches click. Replace the fuel pump fuse.

Step 4. Check

Turn the ignition key to position ON (do not start!) so that the fuel pump creates pressure. Check for leaks. Start the engine and let it idle for 1-2 minutes.

⚠️ Attention! If after replacement the engine does not start or runs intermittently, check:

• The hoses are connected correctly (supply/return are mixed up).
• The integrity of the hose clamps (they may not fully click into place).
• Presence of air in the system (you need to turn the ignition on/off several times).

Typical replacement mistakes and how to avoid them

Even experienced car owners make mistakes that lead to breakdowns or repeated replacements. Here are the most common:

1. Failure to comply with flow direction.

   A filter with reverse installation not only does not clean the fuel, but can also damage the fuel pump. Always check the arrow on the case!

2. Ignoring pressure release.

   Without this, when disconnecting the hoses, gasoline will spray out under pressure - there is a risk of fire or fuel getting into the eyes.

3. Damage to hose clamps.

   Plastic latches are fragile. If they break, the hoses will fly off due to vibration. In this case, you need to replace the clamps (part no. 16515-4M000).

4. Saving on filter.

   Cheap analogues (for example, JS Asakashi) can allow particles larger than 10 microns to pass through, which leads to wear of the injectors.

One more critical error - do not check status fuel hoses when replacing. On cars older than 10 years, they often crack or become tanned. If the hoses have lost their elasticity, they need to be replaced (part no. 16506-4M000 for the supply line).

Frequently asked questions about the fuel filter Murano Z51

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

No. Filter element in Murano Z51 is a paper membrane that cannot be properly cleaned. Flushing will only make the problem worse, as dirt particles will clog the pores even more. The only way out is replacement.

What happens if you drive with a clogged filter?

The consequences depend on the degree of blockage:

• 🔥 Light clogging: increased fuel consumption, loss of power.
• ⚡ Average: jerks during acceleration, difficult starting.
• 💥 Critical: fuel pump failure (replacement cost ~20,000 ₽), failure of injectors.

Is the filter suitable for Nissan X-Trail T31?

Yes, the filters are identical (article number 16400-4M000). However, on X-Trail with engine MR20DE There may be a filter with a different mount. Always check the VIN number or photo of the original part.

Do I need to change the filter when switching to gas (LPG)?

Definitely! Gas dries out the fuel system and the filter clogs faster. Recommended:

• Install filter with enhanced filtration (For example, Mann WK 512).
• Reduce replacement interval to 30,000 km.
• Add to gas tank cleaning additive (For example, Liqui Moly Injection Reiniger) every 5,000 km.

How to check the pressure in the fuel system without a pressure gauge?

The primitive way: click on nipple on the fuel rail (it looks like a tire nipple) with a thin screwdriver. If gasoline splashes heavily, the pressure is normal. If it barely drips, there is a problem with the filter, pump or pressure regulator.

Important! This method is inaccurate and dangerous (risk of fire!). For diagnostics it is better to use a pressure gauge.

Conclusion: is it worth changing the filter yourself?

Replacing the fuel filter with Nissan Murano Z51 - a procedure that can be performed independently in 30–40 minutes, if you follow the instructions and observe safety precautions. Savings will be ~1,500–2,000 ₽ (this is how much they charge at service stations for work).

However, if you are not confident in your skills or the car is under warranty, it is better to turn to professionals. The main thing is don't ignore the replacement, since the cost of repairing a fuel pump or injectors is several times higher than the price of a new filter.

To extend the life of the fuel system it is also recommended:

• 🛢️ Refuel at proven gas stations (for example, Gazpromneft, Lukoil).
• 🧪 Add to tank once every 10,000 km injector cleaner.
• 🔧 Check once every 2 years condition of fuel hoses and fasteners.
