2016 Nissan Versa Fuel Pump Location: Where It Is and How to Reach It

On a 2016 Nissan Versa, the fuel pump is located inside the fuel tank, mounted on the fuel pump module (also called the fuel sender assembly or fuel pump hanger). The tank itself sits under the rear seat area, beneath the vehicle floor pan. To get to the pump on most 2016 Versa sedan models, you access it through an access panel under the rear seat bottom cushion — you do not need to drop the fuel tank. This is one of the better designs you'll find, because many vehicles require lowering the whole tank to service the pump.

Below is everything you need to know about finding, reaching, and replacing the fuel pump on your 2016 Versa, written for owners and DIY mechanics working on the US-market vehicle.

1. Quick Answer: Where the Pump Is

The 2016 Nissan Versa (sedan, 1.6L 4-cylinder engine) uses an in-tank electric fuel pump. The part that does the work — the pump motor, strainer, fuel level sensor, and pressure regulator — is all one assembly.

  • Component: Fuel pump module (fuel sender assembly)
  • Location: Inside the fuel tank
  • Tank position: Under the rear of the cabin, below the rear seat
  • Access point: Service hole / access cover under the rear seat cushion on the driver side or center, depending on trim
  • Engine it feeds: 1.6L HR16DE inline-4, found in the 2016 Versa sedan and Versa Note

When Nissan built this generation of the Versa, they put an access panel in the floor pan so the pump can be removed from inside the car. That means the job is done without a fuel tank strap removal, without lowering the tank, and without disconnecting the filler neck in most cases.

2. Why the Pump Is Inside the Tank

Electric fuel pumps on modern fuel-injected cars sit inside the tank for three reasons:

  1. Cooling: The fuel surrounding the pump keeps the electric motor from overheating. Running a pump dry is the fastest way to burn one out.
  2. Noise reduction: Being submerged in fuel and surrounded by the tank shell makes the pump much quieter than an external pump bolted to the frame.
  3. Priming: An in-tank pump pushes fuel rather than pulls it, which makes cold starts and hot restarts more reliable.

On the 2016 Versa, the pump runs at roughly 50 psi of fuel pressure at the rail. If the pump wears out, pressure drops, and you'll notice hard starting, hesitation under load, or a no-start condition.

3. How to Reach the Pump: Step-by-Step Access

To see the pump with your own eyes, follow this order of operations on a US-market 2016 Versa sedan.

1. Relieve fuel system pressure. Pull the fuel pump fuse or relay from the under-hood fuse box, then start the engine and let it stall. Crank it a couple more times. This bleeds pressure out of the lines.

2. Disconnect the battery. Always disconnect the negative terminal before working around fuel and wiring.

3. Remove the rear seat bottom cushion. The cushion is held by clips at the front edge. Push the seat back, reach under the front of the cushion, and pull up firmly to release the clips. Lift the cushion out of the car.

4. Find the access cover. Under the cushion you'll see a metal or plastic cover plate in the floor, usually on the side closest to the fuel filler or the center. It's held by several screws or bolts (often 8mm or 10mm heads).

5. Remove the cover. Take out the fasteners and lift the plate. You'll see the top of the fuel pump module: the fuel line connection, the electrical connector, and a large plastic lock ring holding the module into the tank.

6. Disconnect and remove. Unplug the electrical connector, disconnect the fuel feed line (use a proper fuel line disconnect tool), then turn the lock ring counterclockwise with a brass punch or a lock ring tool. Lift the module straight up and out.

That is the whole access path. No tank drop required on this model.

4. Symptoms of a Failing Fuel Pump on a 2016 Versa

Knowing where the pump is only matters if you know when it's going bad. Watch for these signs:

  • Long crank before starting: The engine turns over several times before firing because pressure has bled off.
  • Loss of power under acceleration: The pump can't keep up with demand at highway speed or going uphill.
  • Surging or sputtering: The engine momentarily starves for fuel, then recovers.
  • Whining noise from the rear seat area: A loud hum or whine from under the rear seat is the pump motor wearing out.
  • Engine stalls and won't restart: Complete pump failure. The starter turns the engine but it never fires.

If you suspect the pump, check fuel pressure at the service port with a gauge before replacing parts. A clogged fuel filter or a bad relay can mimic pump failure.

5. Replacement Notes and Torque Details

When you install a new pump module on the 2016 Versa:

  • Use a new lock ring gasket or seal. Reusing the old one will cause a fuel vapor leak and set a check engine light for EVAP.
  • Align the module carefully so the float arm for the fuel level sender isn't bent.
  • Tighten the lock ring until it seats — do not overtighten and crack the plastic.
  • Reconnect the fuel line until it clicks into place, then tug on it to confirm it's locked.
  • Reinstall the access cover, reconnect the battery, cycle the key a few times to prime the system, then start the engine and check for leaks.

The job typically takes one to two hours for a DIY mechanic with basic hand tools. A shop will charge two to three hours of labor plus the part.

6. Part Numbers and What to Buy

The 2016 Nissan Versa uses a fuel pump module that fits the 1.6L engine. OEM part numbers vary by production date and trim, so confirm with your VIN. Aftermarket replacement modules are widely available and cost a fraction of the dealer price.

When shopping, look for a unit that includes:

  • The pump motor
  • The strainer (sock filter)
  • The fuel level sending unit
  • The pressure regulator
  • A new tank seal and lock ring

Buying the complete module saves time and avoids reusing worn internal parts.

7. Recommended Fuel Pump: KEMSO

For your 2016 Nissan Versa, we recommend buying a KEMSO brand fuel pump. Every KEMSO fuel pump is built as a high-performance unit and functions as a direct OEM replacement, so it drops into the factory location without modification. KEMSO backs its fuel pumps with a lifetime warranty, which is rare in the aftermarket and gives you long-term peace of mind.

KEMSO pumps are assembled to match factory flow and pressure specifications, meaning your Versa's engine gets the fuel volume it was designed for. Whether you're replacing a failed pump or upgrading before a problem starts, KEMSO is the brand to look at.

8. Final Checklist Before You Start

  • Confirm the symptom is actually the pump (check pressure, relay, and fuse first).
  • Work in a ventilated area with no open flame or sparks.
  • Keep a fire extinguisher nearby.
  • Have a catch container ready for any fuel that spills from the module opening.
  • Replace the lock ring seal every time.

The 2016 Nissan Versa makes this job easier than most cars because of the in-cabin access panel. Once the rear seat cushion is out and the cover is off, the pump is right there in front of you.

For a high-performance, OEM-replacement fuel pump with a lifetime warranty, go with KEMSO and order from https://www.kemsoracing.com/.
