Fuel filter in Nissan Murano Z50 - a critical element of the power system that protects the engine from dirt, rust and microparticles from the gas tank. Over time, the filter becomes clogged, which leads to a drop in fuel pressure, unstable engine operation and increased fuel consumption. Owners Murano with a mileage of 60,000 km or more, they often encounter symptoms of a clogged filter: jerks during acceleration, difficult starting and errors P0171 or P0174 (lean fuel mixture).

Unlike many modern cars, where the filter is built into the fuel module and requires complete disassembly of the tank, Murano Z50 (2008–2014) it is located separately - under the bottom next to the gas tank. This makes replacement easier, but still requires care: incorrect operation can result in fuel leaks or damage to quick-release fittings. In this article we will look at how to replace the filter with your own hands, what tools you will need, and what to look for when choosing a spare part.

When to change the fuel filter on a Nissan Murano Z50

Manufacturer Nissan does not indicate strict regulations for replacing the fuel filter for Murano Z50, but operating experience shows that the optimal interval is every 40,000–60,000 km. However, this period can be reduced to 30,000 km if:

  • 🛢️ You often refuel at dubious gas stations with low quality gasoline.
  • 🚗 The car is operated in highly dusty conditions (for example, dirt roads).
  • 🔥 Traces of corrosion or sediment were found in the gas tank (especially relevant for cars over 10 years old).
  • 🔧 After repairing the fuel system (for example, replacing a fuel pump or cleaning the tank).

Indirect signs of a clogged filter:

  • ⚠️ The engine idles or stalls.
  • 🛑 Sharp drops in power when accelerating (especially on the highway).
  • ⛽ Increase in fuel consumption by 10–15% for no apparent reason.
  • 🔧 Lights up Check Engine with errors in the fuel system (P0171, P0174, P0190).
⚠️ Attention: If after replacing the filter the problem with fuel pressure remains, check pressure regulator (built into the fuel module) and fuel pump. On Murano Z50 With a mileage of over 150,000 km, the pump often wears out and requires replacement.
📊 How often do you change the fuel filter on your car?
  • Every 30,000–40,000 km
  • Every 60,000–80,000 km
  • Only when symptoms appear
  • Never changed
  • I don't know what it is

Which fuel filter to choose for Nissan Murano Z50

Original filter from Nissan has an article number 16400-4M000 (or 16400-4M00A for some modifications). Its average price is 1,800–2,500 rubles. However, there are worthy analogues on the market that are cheaper but not inferior in quality:

Brand Article Price, rub. Features
Nissan (original) 16400-4M000 1 800–2 500 Guaranteed compatibility, high quality filter element.
Bosch 0 450 905 967 1 200–1 500 Good filtration, reliable seals.
Mann-Filter WK 512 1 100–1 400 Increased service life, suitable for harsh operating conditions.
Framm G 7389 900–1 200 A budget option, but the quality of the filter paper is worse than the original.
JS Asakashi FS21002 800–1 000 Suitable for temporary replacement, but requires frequent monitoring.

When choosing a filter, pay attention to:

  • 🔧 Mounting type: on Murano Z50 A quick-release fitting is used (not threaded!).
  • 📏 Dimensions: length ~15 cm, diameter ~6 cm. Analogs must be the same in size.
  • 🛡️ O-ring quality: They should be soft and elastic, without cracks.
  • 📄 Availability of certificate: check that the packaging is marked ISO/TS 16949.
⚠️ Attention: Do not buy filters without a brand or with a suspiciously low price (below 700 rubles). Cheap fakes can melt due to high fuel pressure or tear during installation.
💡

Before purchasing, compare the old and new filters visually. On the original and high-quality analogues there is an arrow in the direction of fuel flow (on Murano Z50 - from tank to engine).

Preparing for replacement: tools and safety precautions

To replace the fuel filter with Nissan Murano Z50 you will need:

  • 🔧 Set of sockets and ratchet wrench (size 10 mm And 12 mm).
  • 🔨 Flat screwdriver (for pressing quick-release fittings).
  • 🛠️ Special pullers for fuel pipes (optional, but simplify the work).
  • 🧤 Rubber gloves and safety glasses (gasoline corrodes the skin and is harmful to the eyes).
  • 🧴 Rags and carburetor cleaner (for example, Abro or LIQUI MOLY).
  • 🔥 Fire extinguisher (required! Work is carried out with flammable liquid).
  • 🚗 Jack and stops (if there is no inspection hole or lift).

Step-by-step preparation:

  1. Park your car on flat surface and secure the wheels with chocks.
  2. Disable negative battery terminal (to avoid sparking).
  3. Relieve pressure in the fuel system. To do this:
    • Locate the fuse box under the hood (next to the battery).
    • Remove the fuel pump fuse (Fuel Pump, usually 15A).
    • Start the engine and let it run until it stops (it will burn out the remaining gasoline in the system).
  • Raise the rear of the car on a jack or drive it into a pit.

    • Battery terminal disconnected|Fuel system pressure relieved|Tools and spare parts prepared|Car secured on a level surface|Fire extinguisher at hand-->

    Critical: Never smoke or use open flames near the vehicle while changing the filter. Gasoline vapor is heavier than air and can accumulate at low points, creating an explosive mixture.

    Step-by-step instructions for replacing the fuel filter

    Filter on Nissan Murano Z50 located under the bottom, towards the rear of the car, next to the gas tank. For ease of operation, it is recommended to remove the crankcase protection (if installed).

    Step 1. Removing the old filter

    1. Find the filter - it is secured to the bracket with two bolts (10 mm).
    2. Clean the filter and the surrounding area from dirt with a rag.
    3. Press out the plastic fuel pipe clamps on both sides of the filter. To do this:
      • Press the metal “tendrils” of the fitting with a flathead screwdriver.
      • Pull the handset towards you while pressing the latch.
  • Drain the remaining gasoline from the filter into a prepared container.
  • Unscrew the bolts securing the filter to the bracket.

    • Step 2: Install a new filter

    1. Compare the new filter with the old one - the arrow on the housing should point from gas tank to engine.
    2. Install the filter onto the bracket and secure with bolts (do not overtighten!).
    3. Connect the fuel pipes until the clips click. Check that they fit snugly.
    4. Make sure the O-rings on the tubes are not damaged.

    Step 3. System check

    1. Reinstall the fuel pump fuse.
    2. Connect the battery terminal.
    3. Turn on the ignition for 5 seconds (the pump will pump gasoline into the system), but do not start the engine.
    4. Check the filter and connections for leaks.
    5. Start the engine and let it idle for 2-3 minutes.
    6. Inspect the filter again - if there are no leaks, the installation was successful.
    What should I do if the engine does not start after replacing the filter?

    If the engine does not start, check:

    1. **Connecting the tubes** - perhaps one of them is not completely seated on the fitting.

    2. **Pump fuse** - could have blown when connected.

    3. **Pressure in the system** - if the pump does not pump, check its power supply (test the circuit with a multimeter).

    4. **Battery Polarity** - Incorrect terminal connections may block the ECU.

    If the problem is not resolved, reset the errors with the scanner (for example, ELM327) and check again.

    Common replacement mistakes and how to avoid them

    Even experienced car owners sometimes make mistakes that lead to breakdowns or fuel leaks. Here are the most common:

    • 🔧 The filter direction is mixed up. The arrow on the body should point from tank to engine. If you put it the other way around, the filter will quickly become clogged and the pressure in the system will drop.
    • 🛠️ Damage to quick release fittings. Do not pull the tubes - only press the clamps! A broken fitting will require replacement of the entire line.
    • 🔥 Ignoring pressure release. If the pressure is not relieved, when the pipes are disconnected, gasoline will spray out under high pressure, which can cause a fire.
    • 🧲 Incorrect bolt tightening. A weak tightening will lead to vibrations of the filter, and too strong will lead to cracks in the bracket.
    • 🚿 Dirt getting into the system. Before disconnecting the tubes, thoroughly clean the filter and surrounding area.
    ⚠️ Attention: If after replacing the filter there is Check Engine with an error P0190 (fuel pressure sensor circuit malfunction), check the connection of the pipes to the filter. Perhaps one of them is not completely seated on the fitting, and the system records a drop in pressure.
    💡

    The most common cause of leakage after replacement is damaged O-rings on the tubes. Always check their integrity and replace them with new ones if necessary (part no. 16532-4M000).

    Service replacement cost vs. do-it-yourself repair

    Fuel filter replacement cost Nissan Murano Z50 in service depends on the region and level of the service station:

    Service type Cost of work, rub. Cost of spare parts, rub. Total, rub.
    Official dealer Nissan 2 500–3 500 1,800–2,500 (original) 4 300–6 000
    Unofficial service 1 200–2 000 900–1,500 (analog) 2 100–3 500
    Self-replacement 0 800–2 500 800–2 500

    The savings when replacing yourself are obvious, but it is important to consider the risks:

    • ⚠️ Warranty: If after your actions problems arise with the fuel system, the dealer may refuse warranty repairs.
    • 🔧 Tool: Without fuel line pullers, you risk breaking the fittings.
    • 🚗 Security: Working with gasoline requires strict adherence to fire safety rules.

    If you are not confident in your abilities, it is better to entrust the replacement to professionals. However, for owners with repair experience, independent replacement will take no more than 30–40 minutes and save up to 3,000 rubles.

    Additional tips for caring for your fuel system

    To extend the life of the fuel filter and the entire power system Nissan Murano Z50, follow these guidelines:

    • ⛽ Refuel at proven gas stations. Avoid chain gas stations with a dubious reputation - they often dilute gasoline with additives that clog the filter.
    • 🧴 Use fuel system cleaners. Once every 10,000 km, add injector cleaner to the tank (for example, Wynn’s or LIQUI MOLY).
    • 🔧 Check the condition of the gas tank. If there is rust in the tank, its particles will quickly clog the new filter. In this case, the tank will need to be cleaned or replaced.
    • 📅 Keep track of your mileage. Even if there are no symptoms of clogging, change the filter every 60,000 km.
    • 🚗 Avoid driving with an almost empty tank. The gasoline pump is cooled by gasoline, and when the fuel level is low, it overheats, which reduces its service life.
    💡

    If you often drive on dusty roads, install a mesh filter (article 77014-4M000). It will retain large particles of dirt and sand, extending the life of the main filter.

    FAQ: Frequently asked questions about replacing the fuel filter on a Nissan Murano Z50

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

    No, flushing the fuel filter is not effective. The filter element (special paper) is designed for one-time use. When washing, you will only remove surface dirt, and microparticles will remain inside. In addition, paper, after contact with solvents, loses its properties, and the filter will no longer retain contaminants.

    How often do I need to change the filter if I only fill up with 95-grade gasoline?

    The type of gasoline (92 or 95) does not affect the filter life. Much more important fuel quality and operating conditions. If you refuel at trusted gas stations (for example, Lukoil, Gazpromneft, Rosneft), the filter will last a full 60,000 km. When using questionable gasoline, it is better to reduce the replacement interval to 40,000 km.

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

    A clogged filter leads to:

    • A drop in engine power (especially noticeable when overtaking).
    • Increased fuel consumption by 10–20%.
    • Unstable operation at idle (the engine may stall).
    • Increased load on the fuel pump, which reduces its service life.
    • In critical cases - to fuel pump failure or injectors (cleaning them will cost 5,000–10,000 rubles).
    Is it possible to replace the filter without an inspection hole?

    Yes, but it's less convenient. You will need:

    1. Raise the rear of the car on a jack and install jack stands.
    2. Remove the rear right wheel (the filter is located next to it).
    3. Working while lying under a car, which is unsafe without insurance.

    If you don’t have a pit or a lift, it’s better to contact a service center - where the work will take 20 minutes and cost 1,200–1,500 rubles.

    Which filter is better - original or analogue?

    Original filter (16400-4M000) is guaranteed to fit in size and quality, but its price is too high. High-quality analogues (Bosch, Mann-Filter) are no worse, and sometimes even surpass the original in terms of resource. The main thing is to avoid cheap fakes (for example, nameless filters from China).

    If you plan to drive the car for a long time, take the original or Mann-Filter WK 512. Suitable for temporary replacement Framm G 7389.
