2006 Nissan Murano Fuel Pump Location: Complete Guide to Finding and Replacing It
The fuel pump in a 2006 Nissan Murano is located inside the fuel tank, and it is typically accessed by removing the rear seat cushion and the access panel underneath it. This means you do not need to drop the fuel tank to reach the pump, which saves significant time and labor compared to many other vehicles. The fuel pump assembly sits directly beneath the rear passenger side of the vehicle, hidden under a metal or plastic cover plate after you lift the rear seat bottom. Understanding exactly where the pump is located and how to access it safely is the first step toward diagnosing fuel delivery problems or replacing a failing unit.
Where Exactly Is the Fuel Pump Located?
The 2006 Nissan Murano uses an in-tank electric fuel pump, which is the standard design for modern vehicles. The pump is mounted inside the fuel tank itself, submerged in gasoline. This design keeps the pump cool and quiet during operation. On the Murano, the fuel tank sits behind the rear axle, underneath the rear passenger compartment.
To access the pump from inside the cabin, you need to remove the rear seat cushion. Once the seat is out, you will see a rectangular access panel on the floor pan. This panel is located on the passenger side (right side) of the vehicle, directly above the fuel tank. Removing this panel gives you direct access to the top of the fuel pump module, including the electrical connectors, fuel lines, and the locking ring that secures the pump in place.
Some older online sources claim you must drop the fuel tank to replace the pump, but that information is incorrect for the 2006 Murano. Nissan designed this vehicle with an access panel specifically to make fuel pump replacement easier. However, if rust or corrosion has seized the access panel screws or the metal cover, some mechanics may still choose to drop the tank as an alternative approach.
Why Knowing the Location Matters
Knowing the exact location of the fuel pump saves you time, money, and frustration. If you take your Murano to a shop and the mechanic tells you they need to drop the fuel tank, you can confidently tell them about the access panel under the rear seat. This simple detail can reduce labor costs significantly. Dropping a fuel tank on a Murano can take three to four hours of labor, while accessing the pump through the interior panel usually takes less than two hours for an experienced mechanic or a skilled DIYer.
Additionally, understanding where the pump sits helps you listen for warning signs. If you hear a whining or buzzing noise coming from the rear passenger area when the ignition is on, that sound is likely coming from a failing fuel pump inside the tank. Knowing that location helps you confirm the source of the problem before you start tearing things apart.
Step-by-Step Guide to Access the Fuel Pump
If you plan to replace the fuel pump yourself, follow these steps carefully. Safety comes first when working with gasoline and electrical components.
Step 1: Safety Preparation
Park the vehicle on a level surface in a well-ventilated area. Disconnect the negative battery terminal to prevent any electrical sparks. Have a fire extinguisher nearby. Wear safety goggles and nitrile gloves to protect yourself from fuel exposure.
Step 2: Depressurize the Fuel System
This step is critical. The fuel system in the 2006 Murano operates at around 43 to 50 psi, and releasing that pressure prevents fuel from spraying out when you disconnect the lines. Locate the fuel pump fuse in the fuse box under the dashboard or in the engine compartment. Remove the fuse, then start the engine and let it run until it stalls. This will relieve the pressure in the fuel lines. Try cranking the engine two or three more times to ensure all pressure is gone.
Step 3: Remove the Rear Seat Cushion
The rear seat cushion is held in place by two bolts at the front edge, one on each side. Remove these bolts using a socket wrench. Once the bolts are out, pull the seat cushion forward and upward to release it from the retaining clips. Set the seat aside in a clean area.
Step 4: Locate and Remove the Access Panel
After removing the seat, look at the floor pan on the passenger side. You will see a metal or plastic cover plate approximately 6 to 8 inches in diameter. This is the access panel. Use a screwdriver or socket to remove the screws or bolts holding it in place. Carefully lift the panel and set it aside. You may need to gently pry it up if it is stuck, but avoid using excessive force as the panel can bend.
Step 5: Disconnect the Electrical Connector and Fuel Lines
Under the access panel, you will see the top of the fuel pump module. There will be an electrical wiring harness connected to the top of the module. Unplug it by pressing the release tab and pulling straight up. Next, you will see two fuel lines: a supply line and a return line. Use a fuel line disconnect tool to release these lines. Have a rag handy to catch any residual fuel that may drip out. Wrap the ends of the fuel lines with plastic wrap or clean rags to prevent debris from entering the system.
Step 6: Remove the Locking Ring and Extract the Pump Module
The fuel pump module is held in place by a large plastic or metal locking ring. This ring can be tight. You may need a special fuel pump removal tool or a large pair of channel locks to turn it counterclockwise. Once the ring is loose, lift it out. Carefully pull the fuel pump module straight up out of the tank. The module is a complete assembly that includes the pump, fuel level sending unit, fuel strainer, and internal wiring. Be prepared for some fuel to spill as you lift it. Place the module in a clean container or on a clean work surface.
Symptoms That Indicate Your Fuel Pump Needs Attention
Before you go through the effort of accessing the fuel pump, you should confirm that the pump is actually the problem. The 2006 Murano's 3.5-liter VQ35DE engine relies on consistent fuel pressure from the pump. When the pump starts to fail, you will notice one or more of these symptoms:
1. Difficulty Starting: The engine cranks for a long time before firing up, or it may not start at all. This is often the first sign of a failing pump because the pump cannot build adequate pressure for the injectors during startup.
2. Engine Stalling While Driving: The engine may suddenly lose power and stall, especially when going uphill, accelerating, or carrying a heavy load. This is a dangerous situation because you lose power steering and brake assist when the engine dies.
3. Hesitation or Stuttering During Acceleration: When you press the gas pedal, the engine may hesitate, stumble, or jerk. This happens because the fuel pump cannot deliver enough fuel to match the increased demand.
4. Rough Idling: The engine may shake or vibrate at idle, and the RPM may fluctuate. The inconsistent fuel supply causes misfires and uneven running.
5. Decreased Fuel Economy: If you notice that you are filling up more often than usual, the fuel pump may be running inefficiently and causing the engine to run rich or lean.
6. Whining Noise from the Rear of the Vehicle: A loud whining or buzzing sound coming from the rear seat area, especially when the fuel tank is low, is a classic indicator of a failing pump motor. The pump struggles to operate and makes noise as it wears out.
7. Check Engine Light: The check engine light may illuminate, and diagnostic trouble codes such as P0087 (fuel rail pressure too low) or P0088 (fuel rail pressure too high) may be stored in the vehicle's computer.
Keep in mind that these symptoms can also be caused by a clogged fuel filter, bad fuel injectors, a faulty fuel pressure regulator, or electrical issues. A proper diagnosis using a fuel pressure gauge is recommended before replacing the pump.
Tools and Parts You Will Need for Replacement
If you decide to replace the fuel pump yourself, gather these tools and parts before you start:
- Socket set (metric sizes, particularly 10mm and 12mm)
- Wrenches (adjustable and combination wrenches)
- Fuel line disconnect tool (required to safely disconnect fuel lines without damage)
- Screwdrivers (flathead and Phillips)
- Fuel pump removal tool or large channel locks
- New fuel pump module (OEM or high-quality aftermarket)
- Safety goggles and nitrile gloves
- Fire extinguisher
- Clean rags and a drain pan
- Plastic wrap or caps for fuel lines
The estimated time for a DIY replacement is two to four hours, depending on your experience level. If you have never done this before, plan for the longer end of that range and take your time.
Choosing the Right Replacement Fuel Pump
When selecting a replacement fuel pump for your 2006 Murano, you have two main options: OEM (Original Equipment Manufacturer) and aftermarket. The OEM part number for the 2006 Murano fuel pump is 17040-CA000, which fits all trim levels (S, SE, SL) with the 3.5L VQ35DE engine.
OEM pumps are manufactured to Nissan's exact specifications and offer the highest reliability. However, they come at a higher price point. Aftermarket pumps are more affordable, but quality varies significantly between brands. Look for a reputable brand that offers a warranty and has good customer reviews.
Regardless of which option you choose, make sure the pump is specifically designed for the 2006 Nissan Murano with the VQ35DE engine. Using a pump from a different application can result in incorrect fuel pressure, poor performance, or premature failure.

Common Mistakes to Avoid During Replacement
When replacing the fuel pump on a 2006 Murano, avoid these common errors that can lead to problems later:
Not Depressurizing the System: Forgetting to relieve fuel pressure can result in a dangerous spray of gasoline when you disconnect the lines. Always remove the fuel pump fuse and let the engine stall before working on the system.
Damaging the Fuel Lines: Using the wrong tool or excessive force on the fuel line connectors can crack or break them. Always use a proper fuel line disconnect tool designed for your vehicle's specific connector size.
Forgetting the O-Ring: The fuel pump module uses a large O-ring to seal it against the fuel tank. If you reuse an old, dried-out O-ring or fail to install the new one correctly, you will have a fuel leak inside the vehicle. Always replace the O-ring with a new one.
Not Cleaning the Area: Before you open the fuel system, clean the area around the access panel and the top of the pump module thoroughly. Any dirt or debris that falls into the fuel tank can clog the new pump or injectors.
Running the Tank Low After Replacement: After installing a new fuel pump, try to keep the fuel tank at least a quarter full. Gasoline cools and lubricates the pump motor. Running the tank dry repeatedly can shorten the life of your new pump.
When to Call a Professional
While replacing the fuel pump on a 2006 Murano is manageable for a DIY enthusiast with moderate mechanical experience, certain situations warrant professional help. If you are uncomfortable working with gasoline, lack the proper tools, or do not have a safe workspace, take the vehicle to a qualified mechanic. Also, if the access panel screws are rusted or stripped, or if you suspect additional issues such as a faulty fuel pump relay or wiring problems, professional diagnosis may save you time and frustration.
A professional mechanic can also test the fuel pump relay and fuse before replacing the pump, ensuring you are not replacing a good pump for an electrical issue. This diagnostic step is often overlooked by DIYers.
