Fuel filter <em>Nissan Murano Z52</em>: when to change, which one to choose and how to replace it yourself

Fuel filter in Nissan Murano Z52 (2015–2022) - this is the inconspicuous but critical element on which the stability of the engine depends VQ35DE or QR25DE. Many owners ignore replacing it until the car begins to sneeze at idle or stall under hard acceleration. But in vain: a clogged filter increases the load on the fuel pump, reduces the life of the injectors and can lead to expensive repairs.

In this article we will look at everything you need to know about the fuel filter. Murano Z52: where is it located (spoiler: not where you are used to!), how often to change it, what original articles and analogues to buy, and we will also give step-by-step replacement instructions taking into account the nuances of a particular model. We will pay special attention A unique feature of the filter in gasoline versions is its integration with the fuel module, which complicates the replacement process compared to diesel counterparts.

Where is the fuel filter located in the Nissan Murano Z52?

Owners Murano Z52 There is often confusion: some sources indicate that the filter is located under the hood or along the fuel line, as in older models. In fact:

• 🔧 In petrol versions (engines VQ35DE 3.5 l and QR25DE 2.5 l) filter built into the fuel module, which is inside the gas tank. This means that to replace it you will have to remove the rear seat and dismantle the entire module.
• ⛽ In diesel versions (engine YD25DDTi, if we are talking about markets where such equipment is available), the filter is taken out separately and located under the hood, next to the high pressure fuel pump.
• ⚠️ On Murano Z52 after restyling in 2019, the design has not changed - the filter is still integrated into the module.

This arrangement has advantages (compactness, protection from external influences) and disadvantages - Changing the filter requires care, since you will have to work with fuel hoses and electrical connectors. In addition, many car owners mistakenly buy an external filter (for example, from Nissan X-Trail T32), which is not suitable for Murano Z52.

Signs of a clogged fuel filter

Filter in Murano Z52 clogs gradually, and symptoms do not appear immediately. In the early stages, they can easily be confused with faulty sensors or spark plugs. Pay attention to the following “bells”:

• 🚗 Jerks during acceleration, especially at speeds of 60–100 km/h. The engine seems to be “stumbling”, although the speed is stable.
• 🔥 Dips when pressing the gas pedal — the car reacts with a delay or jerks.
• ⚡ Increased fuel consumption (1–2 liters more than usual) while maintaining the driving style.
• 🛑 Difficult start “cold” or “hot”, although the battery and starter are fine.
• 💨 Power Loss at high speeds - the car “does not pull” when overtaking or climbing.

If you ignore these symptoms, the consequences can be serious:

⚠️ Attention! A clogged filter causes the fuel pump to work harder, causing it to premature wear (cost of a new pump for Murano Z52 - from 15,000 rubles). In critical cases, dirt particles penetrate the nozzles, causing them to clog (ultrasonic cleaning will cost 8,000–12,000 rubles).

To confirm the diagnosis, you can check fuel rail pressure using a pressure gauge. Normal indicators for Murano Z52:

• At idle speed: 2.8–3.2 bar.
• When releasing gas: short-term drop to 2.5 bar, then recovery.
• When you press the gas: increase to 3.5–4.0 bar.

If the pressure is below normal, the filter or pump is faulty. For an accurate diagnosis, it is better to contact a service station with equipment to check the performance of the pump.

When to change the fuel filter: regulations and real terms

Manufacturer Nissan in the manual for Murano Z52 indicates that the fuel filter does not require replacement throughout the entire service life of the vehicle. However, this statement is only true for ideal operating conditions: high-quality fuel, no corrosion in the tank, regular refueling at proven gas stations.

In Russian realities the situation is different:

Operating conditions	Recommended replacement interval	Notes
Refueling at proven network gas stations (Lukoil, Gazpromneft, Rosneft)	Every 60,000–80,000 km	When using fuel with an octane rating of at least 95
Use in high humidity conditions or frequent short trips	Every 40,000–50,000 km	Moisture and condensation accelerate tank corrosion and filter clogging
Refueling at little-known gas stations or using 92 gasoline	Every 30,000–40,000 km	Low quality fuel reduces filter life by 1.5–2 times
Aggressive driving style (frequent acceleration, high revs)	Every 50,000–60,000 km	Increased fuel consumption accelerates clogging

In addition to mileage, the need for replacement is affected by:

• 🕒 Vehicle age: if Murano Z52 older than 5 years, the filter should be replaced even with low mileage - over time, the paper element loses its filtering properties.
• 🌡️ Climatic conditions: in regions with sharp temperature changes (for example, Siberia), the filter clogs faster due to condensation.
• 🔧 Service history: If the previous owner did not change the filter, it is better to do this immediately after purchase.

Choosing a fuel filter: original vs analogues

For Nissan Murano Z52 Only filters compatible with the fuel module are suitable Denso or Bosch (depending on the year of manufacture). Supplies original spare parts Nissan under the articles:

• 🔹 Original filter (complete with module): 17040-4M50A (for petrol versions).
• 🔹 Filter separately (if the module is ok): 16400-4M500 or 16400-4M505.
• 🔹 For diesel versions: 16400-JD00A (fine filter).

The cost of the original filter assembled with the module reaches 20,000–25,000 rubles, so many people choose analogues. Best options:

Manufacturer	Article	Price, rub.	Notes
Denso	953-0101	3 500–4 200	Direct analogue of the original, high quality filter element
Bosch	0 450 905 318	2 800–3 300	Suitable for modules Denso, but may require modification of the seals
Mahle	KX 338/12 D	3 000–3 700	Good filtration, but less common in stores
JS Asakashi	FS22005	2 500–3 000	Budget option, but the quality of the filter paper is worse than the original

When choosing an analogue, pay attention to:

• 📏 Dimensions: The filter must fit exactly into the module seat. Even a slight discrepancy will lead to air leaks.
• 🔄 Flow direction: There is an arrow on the filter housing indicating the movement of fuel. Install “back to front” - guaranteed pump failure.
• 🛡️ O-ring quality: Cheap analogues can leak after several thousand kilometers.

⚠️ Attention! Do not buy filters from unknown brands (for example, Patron, SCT or Finwhale) - they are often counterfeited. Original Denso or Bosch will last 2-3 times longer, even despite the higher price.

Step-by-step instructions for replacing the fuel filter

Replacing the filter in Nissan Murano Z52 Requires caution and compliance with safety precautions. Before starting work:

• 🔋 Disconnect the negative terminal of the battery.
• ⛽ Make sure there is less than 1/4 of fuel in the tank (working with a full tank is dangerous!).
• 🔥 Have a fire extinguisher on hand - gasoline vapors are highly flammable.

To replace you will need:

• 🔧 Set of sockets and wrench for 10.
• 🔨 Plastic remover for clips (so as not to break the module mounts).
• 🧤 Rubber gloves and rags.
• 🛠️ New filter (or module assembly) and tank O-ring (17352-4M500).

Step 1. Removing the rear seat

Lift the rear seat cushion (it is secured with latches) and remove the trunk trim. Underneath it you will see the fuel module hatch - it is secured with 4 screws. Carefully unscrew them and remove the cover.

Step 2: Disconnecting electrical connectors

Disconnect the fuel pump power connector (usually black) and the fuel level sensor connector (gray). To avoid damaging the clips, press the clips on the sides and pull up.

Step 3: Removing Fuel Hoses

The hoses are secured with quick-release couplings. To disconnect them:

1. Press the plastic clips on both sides.
2. Pull the hose up while rocking it from side to side.
3. Place a container - gasoline may leak out of the hoses!

Step 4. Removing the fuel module

The module is attached to the tank using a plastic ring with 8 bolts for a 10mm head. Unscrew them criss-crossso as not to deform the flange. After this, carefully remove the module, tilting it to the side so as not to bend the level sensor float.

Step 5: Replace the filter

If you are only changing the filter (not the entire module), disassemble it:

1. Remove the bottom cover of the module (it snaps into place).
2. Remove the old filter and install the new one, observing the direction of flow (arrow on the housing).
3. Check the condition of the coarse mesh - if it is clogged, wash it or replace it.

Step 6. Assembly and testing

Install the module in reverse order. After assembly:

1. Connect the battery.
2. Turn on the ignition for 5 seconds (the pump will pump in fuel), but do not start the engine.
3. Check the tightness of the connections - there should be no smell of gasoline.
4. Start the car and let it idle for 2-3 minutes.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes when replacing the fuel filter in Murano Z52. Here are the most common:

• 🔌 Incorrect hose connection: if you confuse the supply and return, the engine will run intermittently or will not start at all. The supply hose is usually marked with a green mark.
• 🔧 Retightening the module mounting bolts: This leads to flange deformation and fuel leakage. Tighten the bolts firmly 5–7 Nm.
• 🧹 Dirt getting into the tank: Before removing the module, clean the area around the hatch with a vacuum cleaner. Even fine dust can clog the new filter.
• ⚡ Ignoring O-ring replacement: The old ring loses its elasticity and can allow gasoline vapors to pass through. Its article number is 17352-4M500.

Another typical problem is error P0171 (lean mixture) after replacing the filter. It occurs due to:

• Air leaks through loose hose connections.
• The coarse mesh is clogged (they forgot to wash it).
• Malfunction of the fuel pressure sensor (it is built into the module).

If an error appears, check:

1. All connections are tight (you can use a smoke generator).
2. Rail pressure (must be at least 3.0 bar at idle).
3. Condition of the vacuum hoses (they may crack when dismantling the module).

What should I do if the engine starts to shake after replacing the filter?

If the engine stalls or is unstable, the cause may be:

1. **Air leak** through cracks in the hoses or a loose module ring.

2. **Clogged injectors** - dirt particles from the old filter could get into them.

3. **Fuel pump malfunction** - If it is worn out, a new filter will not solve the problem.

4. **Error in connecting the connectors** (for example, the wires of the level sensor are mixed up).

For diagnostics, check:

- Compression in the cylinders.

- Condition of the spark plugs (carbon deposits or gap).

- Fuel pressure in the rail (pressure gauge).

If the problem persists, diagnostics at a service station are required with reading errors via CONSULT-III or Launch X431.

Cost of service replacement vs self-repair

Fuel filter replacement price in Nissan Murano Z52 varies depending on region and type of service:

Service type	Cost of work, rub.	Cost of spare parts, rub.	Total, rub.
Official dealer Nissan	8 000–12 000	20,000–25,000 (original module)	28 000–37 000
Unofficial service	3 500–5 000	3,000–6,000 (analog Denso/Bosch)	6 500–11 000
Self-replacement	0	3 000–6 000	3 000–6 000

Replacement yourself saves money up to 80% cost, but requires:

• 🛠️ Skills in working with the fuel system (risk of fire!).
• 🔧 Special tool (clip remover, head remover).
• 🕒 Time (2-3 hours for the first time).

If you are not confident in your abilities, it is better to contact the service. This is especially true when:

• 🔥 There is rust in the tank (the tank needs to be cleaned or replaced).
• ⚡ The engine has errors in the fuel system (P0171, P0174).
• 🛑 The fuel pump makes strange noises (the entire module may need to be replaced).

FAQ: Frequently asked questions about the Nissan Murano Z52 fuel filter

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

No, washing will not restore the filtering properties of the paper element. Moreover, aggressive detergents can damage its structure, after which dirt particles will enter the fuel system. The only option is replacement.

How can I check if the filter they sold me is original?

Original filters Nissan or Denso have:

• Clearly marked with the article number and manufacturer's logo.
• High-quality packaging with a hologram (with Nissan).
• Sealing rings fit tightly without gaps.

Counterfeits often have blurred fonts on the body, crooked seams, or the smell of low-quality plastic.

What happens if you drive with a clogged filter?

The consequences depend on the degree of blockage:

• Easy degree: increased fuel consumption, loss of dynamics.
• Average degree: jerks during acceleration, difficult starting, errors P0171/P0174.
• Critical degree: failure of the fuel pump, clogged injectors, failure of the catalyst (replacement cost - from 50,000 rubles).

Do I need to change the coarse mesh when replacing the filter?

Yes, it is recommended to at least wash the mesh (aka “spider”), or better yet, replace it. Its article number is 16035-4M500. The cost is small (about 500 rubles), but its clogging can negate the effect of the new filter.

Is it possible to install an external fuel filter instead of the built-in one?

Technically it's possible, but it's not recommended. The built-in filter is designed for a specific pressure and fuel flow in the system Murano Z52. Installing an external filter may result in:

• Pressure drop in the ramp (due to additional resistance).
• Overheating of the pump (it will work with increased load).
• Loss of warranty (if the car is under warranty).

If you still decide to install an external filter, choose models with with a capacity of at least 150 l/h and mount it after standard module, and not instead of it.
