Nissan Murano Fuel Pump Location: Where It Is and How to Access It

The fuel pump on every Nissan Murano from 2005 through 2024 is located inside the fuel tank, and on most models you access it from underneath the rear seat cushion. This holds true for the first-generation Z50 (2003–2007), the second-generation Z51 (2008–2014), and the third-generation Z52 (2015–2024) models. Instead of dropping the fuel tank, you remove the rear seat bottom to reach a metal access panel in the floor. Once that panel is lifted, the complete fuel pump module — including the pump motor, fuel level sending unit, and often the fuel pressure regulator — is right there. This design makes the job easier than you might expect, but it still requires careful work and proper safety precautions. Below we’ll walk through exactly where to find it, how to safely get to it, and what to do once you’re there.

Understanding the Fuel Pump Location by Model Year

2003–2007 Nissan Murano (Z50): The fuel pump is an in-tank electric unit mounted inside the fuel tank. Access is gained by removing the rear seat cushion and then removing a round or oval metal access cover in the floor pan. The pump assembly includes the pump motor, a fuel level sensor, and a sock-type fuel filter. The system on these years is generally a returnless design, meaning there is no separate fuel return line running back to the tank.

2008–2014 Nissan Murano (Z51): These models follow the same basic layout. The fuel pump module sits inside the fuel tank, and you access it through the rear seat floor. The 2009 model year is notable because it uses a dual fuel pump system — two pumps inside the tank, not just one. The primary pump handles normal fuel delivery, while a secondary pump assists during high-load conditions or when additional pressure is needed. Both pumps are contained within the same module assembly, so you access them together through the same single access panel under the rear seat.

2015–2024 Nissan Murano (Z52): The third-generation Murano keeps the same in-tank pump location. A 2018 model, for example, uses a fuel pump module assembly accessed by removing the rear seat cushion and lifting the access cover. The procedure is the same as earlier generations.

Step-by-Step: How to Access the Fuel Pump on Your Murano

Before you start, the most important thing you can do is relieve fuel system pressure. A full fuel system is under pressure, and opening it without depressurizing can spray fuel everywhere. To relieve pressure, pull the fuel pump fuse or relay from the fuse box (the fuse box cover diagram will tell you which one), then start the engine and let it run until it stalls. Crank the engine for another two to three seconds to make sure the lines are empty, then turn the ignition OFF.

1. Disconnect the battery. Remove the negative battery cable using a 10mm socket. This prevents any accidental electrical sparks while you work near fuel vapors.

2. Remove the rear seat cushion. On most Murano models, the rear seat bottom is held in place by two or three clips at the front edge. Use a trim clip removal tool to pop these clips loose, then lift the front of the cushion up and pull it forward to release it. Once it’s free, set the cushion aside where it won’t pick up fuel odors.

3. Clean the area thoroughly. Use a handheld vacuum to remove any dirt, dust, or debris from around the access cover. Even a small amount of dirt falling into the fuel tank can damage the new pump. Vacuum the cover and the surrounding floor area, then wipe the surface clean with a shop towel.

4. Remove the access cover. The access cover is a metal plate, usually round or oval, sealed with butyl sealer. Use a small flat-blade screwdriver and a non-sparking plastic scraper to carefully lift the cover without bending it. Peel back the butyl sealer slowly so you can reuse it later if it’s still in good shape.

5. Disconnect the electrical connector and fuel lines. Once the cover is off, you’ll see the top of the fuel pump module. First, disconnect the electrical connector by pressing the release tab and pulling it apart. Then use a fuel line quick-disconnect tool set to release the fuel lines from the pump module. Place a rag underneath to catch any fuel drips.

6. Remove the lock ring and lift out the module. The pump module is held in place by a large lock ring. Use a fuel pump lock ring wrench or a brass punch and hammer to turn the ring counterclockwise. Once the ring is loose, lift it out of the way and carefully pull the pump module straight up out of the tank. The module will be full of fuel, so tilt it slowly to drain the fuel back into the tank before lifting it all the way out.

Common Symptoms of a Failing Fuel Pump

Knowing the signs of a bad fuel pump can save you time and frustration. Here are the most common symptoms Murano owners report across all generations:

• Hard starting: The engine cranks for a long time before it starts, or it may not start at all. This is often the first sign of low fuel pressure.
• Stalling: The engine dies unexpectedly, especially during acceleration or when climbing a hill. Inconsistent fuel delivery is the usual cause.
• Loss of power: The car feels sluggish, particularly at highway speeds. The engine isn’t getting enough fuel to perform properly.
• Hesitation when accelerating: Pressing the gas pedal results in a stumble or delay before the car responds.
• Rough idle: The engine runs unevenly or shakes when stopped at a light.
• Whining noise from the fuel tank: A healthy fuel pump makes a quiet hum. A loud buzzing or whining sound, especially when the fuel level is low, means the pump is struggling.
• Check Engine Light: A failing pump can trigger codes like P0087 (fuel rail/system pressure too low), P0088 (pressure too high), or P0230 (fuel pump primary circuit).

How to Confirm the Fuel Pump Is the Problem

Before you replace the pump, it’s smart to verify that the pump is actually the issue and not a relay, fuse, or wiring problem.

Listen for the prime. Turn the ignition key to the ON position without starting the engine. You should hear a brief buzzing sound from the rear of the vehicle for about two to three seconds. This is the fuel pump pressurizing the system. No sound means the pump isn’t getting power, or the pump itself has failed.

Check the fuel pump relay and fuse. Locate the fuel pump relay in the engine compartment fuse box. Use a multimeter to test the relay for proper operation. Inspect the fuse for any signs of a blown filament or corrosion. Even a small amount of corrosion can prevent the pump from running.

Measure fuel pressure. This is the most reliable way to confirm a bad pump. Connect a fuel pressure gauge to the test port on the fuel rail. With the engine running, the pressure should be around 40 to 60 psi on most Murano models. For the 2009 Murano, the specification is 45 to 50 psi. If the pressure is significantly lower than spec, the pump is likely failing.

Check for voltage at the pump connector. If you’ve already accessed the pump module, use a multimeter to check for battery voltage at the pump’s electrical connector when the ignition is turned ON. If there is voltage but the pump doesn’t run, the pump itself is bad. No voltage means the problem is in the wiring, relay, or fuse.

Why the Fuel Pump Is Inside the Tank

Automakers mount the fuel pump inside the tank for several good reasons. First, the fuel itself acts as a coolant for the pump motor, which keeps it from overheating and extends its lifespan. Second, an in-tank pump is quieter than an externally mounted pump; the fuel and the tank absorb most of the noise. Third, this design virtually eliminates the risk of vapor lock, where fuel vaporizes in the fuel lines and prevents the engine from getting fuel. Finally, in-tank placement reduces the number of external fuel line connections, which means fewer potential leak points.

Replacement Cost and Time Estimates

Replacing the fuel pump on a Nissan Murano is an intermediate-level DIY job. Expect to spend two to four hours from start to finish, depending on your experience level and whether you run into any rusted fasteners or stubborn lock rings.

The cost of the job varies by model year and whether you use OEM or aftermarket parts. For a 2007 Murano, the total cost including parts and labor typically runs $400 to $1,000. Fuel pump modules themselves range from about $150 to $450 for aftermarket units, while OEM parts can run $350 to $750. Labor at a shop will add roughly $150 to $600 at typical shop rates of $75 to $150 per hour.

Safety Tips for the Job

Working with fuel always carries risk. Follow these rules to stay safe:

• Work outside or in a very well-ventilated area. Gasoline vapors are heavier than air and can collect in low spots. A garage with the door open is acceptable; a closed garage is not.
• Keep a Class B fire extinguisher nearby. Make sure it’s rated for flammable liquid fires.
• No smoking, no open flames, and no heat guns. Even a spark from static electricity can ignite fuel vapors.
• Disconnect the battery negative cable. This prevents any electrical spark while you’re opening the fuel system.
• Do not use power tools near the open fuel tank. The risk of a spark is too high. Use hand tools only.
• Wear safety glasses and nitrile gloves. Fuel can irritate your skin and eyes, and you don’t want to get it on your hands.
