2016 Kia Soul Fuel Pump Location: Where It Is and How to Reach It

The fuel pump on a 2016 Kia Soul is located inside the fuel tank, mounted on the fuel pump module assembly under the rear seat area. You do not remove it from the engine bay. To get to it, you lift the rear seat cushion, remove the access cover on the floor, and disconnect the pump module from the top of the tank. This article walks you through the exact location, the tools you need, the step‑by‑step access procedure, the symptoms of a failing pump, replacement options, and what a shop will charge versus doing it yourself.

1. Where Exactly the Fuel Pump Sits on a 2016 Kia Soul

The 2016 Kia Soul uses an in‑tank electric fuel pump. That means the pump, the sending unit (fuel level sensor), the filter/strainer, and the fuel pressure regulator are all built into one assembly called the fuel pump module. This module is installed through a large round opening in the top of the fuel tank.

On the Soul, the fuel tank sits under the rear of the vehicle, roughly beneath the rear passenger seat and rear floor pan. The top of the tank has a service port, and Kia put an access panel in the vehicle floor so a technician does not have to drop the whole tank just to change the pump.

Here is the layout in plain terms:

  • Fuel tank: under the rear of the car, behind the rear axle line
  • Fuel pump module: inside the tank, at the top, near the center/rear section
  • Floor access cover: under the rear seat cushion, on the passenger side in most US‑market models
  • Electrical connector and fuel lines: on top of the module, reachable once the cover is off

Because the pump is electric and submerged in gasoline, it is cooled and lubricated by the fuel itself. That design is why running the tank consistently near empty can shorten pump life — the pump loses its cooling bath and runs hotter.

Why Kia Put It Inside the Tank

Older vehicles often used a mechanical pump on the engine or an inline electric pump mounted on the frame rail. Modern cars like the 2016 Soul moved the pump inside the tank for three reasons:

  1. Less vapor lock and better hot‑fuel handling — the fuel around the pump keeps it cool.
  2. Quieter operation — the tank and surrounding structure dampen pump noise.
  3. Lower fire risk — the pump is sealed inside the tank instead of sitting in the engine bay with ignition sources nearby.

The trade‑off is access. Replacing it means opening the tank from above, which is why knowing the access‑panel location saves a lot of labor time.

2. Symptoms That Point to a Failing Fuel Pump

Before you open anything, confirm the pump is actually the problem. A no‑start condition has many causes, and the fuel pump is only one of them.

Common signs of a worn or failing pump:

  1. Engine cranks but will not start — the starter turns the engine over normally, but it never fires because no fuel is being delivered.
  2. Long crank time before starting — the engine turns for several seconds before catching, especially after the car has been sitting.
  3. Loss of power under load — the Soul accelerates fine around town but stumbles, hesitates, or surges when merging onto a highway or climbing a hill.
  4. Surging at steady speed — the vehicle suddenly speeds up or slows down slightly while cruise control or a steady throttle is held.
  5. Whining or humming from the rear seat area — a loud, high‑pitched whine that rises with engine speed usually means the pump motor is wearing out.
  6. Stalling and then restarting — the engine dies while driving and may restart after a few minutes once the pump cools down.
  7. Fuel gauge reading wrong — on the Soul, the level sensor is part of the same module, so a pump‑related fault can also cause an inaccurate or dead gauge.

Important checks before replacing the pump. A bad fuel pump relay, a blown fuse, a failed fuel pump resistor (on some trims), a clogged fuel filter, or a faulty crankshaft position sensor can mimic pump failure. Always check the fuel pump fuse and relay in the engine‑bay fuse box first, and listen for the pump priming. When you turn the key to the ON position (without starting), you should hear a faint two‑second hum from under the rear seat. No hum usually means an electrical supply issue or a dead pump.

3. Tools and Safety Supplies You Need

Working on a fuel system is not like changing an air filter. Gasoline vapor is flammable, and you are opening a sealed tank. Prepare properly.

Tools:

  • Flat‑head and Phillips screwdrivers
  • 10 mm socket and ratchet (for seat bolts and cover screws)
  • Trim panel removal tool (optional, reduces broken clips)
  • Fuel line disconnect tool (for the quick‑connect fittings, often 5/16 in or 3/8 in)
  • Locking pliers or a fuel pump module ring removal tool (spanner wrench)
  • Jack and jack stands only if you choose to drop the tank — not needed for the access‑panel method
  • Shop towels and a drain container

Safety supplies:

  • Safety glasses
  • Nitrile or mechanic gloves resistant to fuel
  • A fire extinguisher rated for flammable liquids (Class B) within reach
  • No sparks, no smoking, no open flame in the work area
  • A well‑ventilated space — open the garage door or work outdoors

Practical tip: Park the Soul with less than a quarter tank of fuel. A nearly empty tank means less weight, less spillage, and far less mess when you lift the module out.

4. Step‑by‑Step: Reaching the 2016 Kia Soul Fuel Pump Location

This is the access‑panel method used by most technicians in the United States. It avoids dropping the tank.

Step 1: Relieve Fuel System Pressure

Locate the fuel pump fuse or relay in the engine compartment fuse box. With the engine off, crank the engine for a few seconds (or use the relay‑pull method) to bleed off pressure in the lines. Then disconnect the negative battery cable and secure it away from the terminal. This step prevents a spark near fuel vapor.

Step 2: Lift the Rear Seat Cushion

The rear seat bottom cushion on the 2016 Soul is held by hooks at the front and bolts or clips at the rear. Reach under the front edge of the cushion and pull up firmly to release the front hooks. Slide the cushion forward and lift it out of the vehicle. Set it aside. On most trims you will now see the metal floor and one or two round or rectangular access covers.

Step 3: Remove the Access Cover

The fuel pump access cover is typically on the passenger side of the rear floor pan, though verify by looking for the wiring harness entering the cover. Remove the screws (usually 10 mm or Phillips) around the cover. Lift the cover off. You will see the top of the fuel pump module: a large plastic locking ring, the electrical connector, and the fuel line fittings.

Step 4: Disconnect the Electrical Connector and Fuel Lines

Press the tab and pull off the wiring harness connector from the module. For the fuel lines, use the appropriate disconnect tool on the quick‑connect fittings. Expect a small amount of fuel to dribble out — have towels ready. Cap or plug the lines to keep dirt out of the system.

Step 5: Remove the Locking Ring

The module is held by a large threaded plastic or metal ring. Use a fuel pump module spanner wrench or a brass punch with a hammer to turn the ring counterclockwise. Do not use steel tools that can spark. Once the ring is free, lift it out.

Step 6: Lift Out the Fuel Pump Module

Carefully lift the module straight up and out of the tank. The float arm for the sending unit may catch, so tilt slightly as needed. Place the old assembly in a drain pan. Note the orientation of the module so the new one goes in the same way.

Step 7: Compare and Install the New Module

Compare the new pump module to the old one: connector shape, float arm, strainer, and mounting tabs must match. Transfer any reusable parts if your kit does not include them (usually just the seal/gasket — always use a new seal). Lower the new module into the tank, seat it, tighten the locking ring by hand then snug it with the tool. Reconnect the fuel lines until they click, and plug in the electrical connector.

Step 8: Reassemble and Test

Reinstall the access cover and screws. Put the rear seat cushion back, pushing the rear hooks in first then pressing the front down until the clips lock. Reconnect the battery. Turn the key to ON (not start) two or three times to let the pump prime and build pressure. Check for leaks at the fittings. Then start the engine and let it idle while you inspect again for leaks.

5. Common Mistakes to Avoid

  1. Skipping pressure relief. Opening a pressurized line sprays fuel. Always depressurize first.
  2. Reusing the old seal. The tank sealing ring/seal is one‑time use on most applications. A reused seal causes a fuel odor and an evaporative emissions (EVAP) code.
  3. Bending the float arm. The fuel level sender arm is thin. If bent, the gauge reads wrong forever.
  4. Forcing the locking ring. If it will not turn, check for a hidden tab or dirt. Forcing it cracks the ring and the tank opening.
  5. Ignoring the strainer. If the old pump failed from a contaminated tank, a new pump will fail again. Clean the tank or replace the strainer.
  6. Not checking the relay and fuse. Many "bad pumps" are actually a forty‑dollar relay.

6. Replacement Cost: DIY vs. Shop in the US Market

Knowing the cost helps you decide whether to do it yourself.

DIY parts cost: A quality replacement fuel pump module for a 2016 Kia Soul generally runs between $90 and $260 depending on brand, whether it includes the sending unit, and whether you buy the module assembly or just the pump insert. Budget brands sit at the low end; OEM‑equivalent kits with a lifetime warranty sit higher.

Shop labor cost: Because the Soul has a floor access panel, a shop can usually do the job in 1.5 to 2.5 hours. At typical US independent shop rates of $110 to $170 per hour, labor lands around $165 to $425. Total installed cost at a shop commonly falls between $300 and $700.

Dealer cost: At a Kia dealership with OEM parts, the total is often $550 to $950, depending on regional labor rates and whether the tank has to be dropped on your specific configuration.

Time saving note: If your vehicle does not cooperate with the access panel — for example, severe rust on the cover screws or an unusual trim layout — dropping the tank adds one to two hours and the job becomes much harder without a lift.

8. Maintenance Habits That Extend Pump Life

Replacing the pump is only half the job. These habits help the new one last:

  1. Keep the tank above a quarter full. The fuel cools the pump. Running on fumes overheats it.
  2. Replace the fuel filter on schedule if your setup has an inline serviceable filter.
  3. Buy fuel from high‑volume stations. Water and sediment in cheap or stale gasoline damage the strainer and pump.
  4. Address a check engine light early. Lean codes or EVAP codes can point to delivery problems before total failure.
  5. Listen for changes. A new whine or a longer crank is the pump telling you something before it strands you.

9. Frequently Asked Questions

Is the 2016 Kia Soul fuel pump under the back seat?
Yes. The pump module is inside the fuel tank, and the tank has a service access port under the rear seat cushion area, usually on the passenger side.

Do I have to drop the fuel tank to replace it?
Normally no. The Soul has a floor access cover, so the module comes out from above. Dropping the tank is only needed if the access panel is blocked or the fasteners are seized.

How long does a replacement take?
An experienced do‑it‑yourself mechanic usually finishes in one to two hours. A shop with the right tools often completes it in under two hours.

What size tools are needed for the seat and cover?
The seat cushion is held by hooks and typically 10 mm bolts or clips. The access cover uses small screws, often 10 mm hex or Phillips.

Can I drive with a failing fuel pump?
You can for a short time, but it is a bad idea. A pump that fails completely will leave you stranded, sometimes in unsafe traffic. Replace it at the first clear symptom.

Final Word

The 2016 Kia Soul fuel pump location is inside the fuel tank, accessible through a floor panel under the rear seat — not in the engine bay. Confirm the pump is at fault before you buy parts, work safely with fuel, and always install a new seal. Whether you turn the wrenches yourself or hand the job to a shop, using a dependable, direct‑fit, high‑performance replacement makes the difference between a repair that lasts and one you repeat.
