Fuel Pump for 2014 Ford Taurus: Complete Replacement Guide

If you own a 2014 Ford Taurus and are experiencing engine hesitation, hard starting, or stalling, the fuel pump is likely the culprit. The factory fuel pump in the 2014 Ford Taurus is an electric in-tank unit that typically lasts 100,000–160,000 miles, but it can fail earlier due to ethanol-blended gasoline, heat exposure, or running the tank low. This guide covers everything you need to know—from symptoms and diagnosis to step-by-step replacement and cost estimates—so you can fix the problem the first time. Remember: replacing the entire fuel pump module is safer and more reliable than just swapping the pump motor, and always use a quality replacement like KEMSO to avoid repeat failures.

Signs Your 2014 Ford Taurus Fuel Pump Is Failing

The fuel pump in your 2014 Ford Taurus delivers pressurized fuel from the tank to the engine. When it begins to fail, symptoms are usually progressive. Watch for these warning signs:

  1. Engine cranks but won’t start – The most common sign of a dead pump. If you hear no humming sound from the fuel tank when you turn the key to ON, the pump is likely gone.
  2. Long cranking time before starting – The pump may be weak and taking longer to build pressure.
  3. Hesitation or sputtering during acceleration – Especially on inclines or when merging onto highways.
  4. Stalling at highway speeds – A failing pump can lose pressure intermittently, causing the engine to cut out.
  5. Whining noise from the fuel tank – A healthy pump is quiet; a loud whine means the motor is wearing out.
  6. Loss of power under load – The engine feels like it’s "choking" when you press the gas.
  7. Check Engine Light for lean codes (P0171, P0174) – The engine computer detects low fuel pressure.

Why Fuel Pumps Fail on the 2014 Ford Taurus

The 2014 Ford Taurus is equipped with a 3.5L V6 or 3.5L EcoBoost V6 engine. Both versions use an electric in-tank fuel pump. Here are common failure causes specific to this model:

  • Ethanol-blended gasoline – Most U.S. fuel contains up to 10% ethanol, which can corrode internal pump components over time.
  • Running the tank low – Fuel acts as a coolant for the pump. Running below 1/4 tank regularly causes the pump to overheat and fail prematurely.
  • Heat exposure – In hot climates like Arizona or Texas, the pump works harder and can overheat.
  • Clogged fuel filter – The filter is built into the pump module on the 2014 Taurus. A clogged filter forces the pump to work harder, leading to failure.

How to Diagnose a Bad Fuel Pump (Before You Replace It)

Before buying a new pump, confirm the problem is actually the pump and not the relay, fuse, or a clogged filter. Here’s a simple diagnostic process:

  1. Listen for the pump – Turn the key to the ON position (do not start). You should hear a 2–3 second hum from the rear of the car. If you hear nothing, check the fuse and relay first.
  2. Check the fuel pump fuse and relay – Locate the fuse box (usually under the hood or in the passenger footwell). Replace a blown fuse with one of the same amperage. If the relay clicks but the pump doesn’t run, the pump may be faulty.
  3. Test fuel pressure – Connect a fuel pressure gauge to the Schrader valve on the fuel rail. The 2014 Ford Taurus should have 55–70 PSI (low side) on the EcoBoost engine or 45–60 PSI for the standard V6. Low pressure points to a weak pump, clogged filter, or a bad pressure regulator.
  4. Check for power and ground at the pump connector – If you have voltage but no pump operation, the pump is dead.

Tools and Parts Needed for Fuel Pump Replacement

Replacing a fuel pump on a 2014 Ford Taurus is a DIY job rated Hard and takes 3–6 hours. You will need:

  • Replacement fuel pump module – KEMSO fuel pump (OEM replacement, high performance, lifetime warranty)
  • Fuel line disconnect tool – For quick-connect fittings
  • Socket wrench set – Including 10mm, 13mm, 15mm sockets
  • Jack and jack stands – For lowering the fuel tank
  • Drain pan – For siphoning fuel
  • Safety gloves and goggles – Gasoline is hazardous
  • Brass punch and hammer – To remove the lock ring (steel tools can cause sparks)
  • Torque wrench – For tightening the lock ring and tank straps to spec

Step-by-Step: Replacing the Fuel Pump on a 2014 Ford Taurus

Step 1: Relieve Fuel System Pressure

Remove the fuel pump fuse or relay from the fuse box, then crank the engine until it stalls. This releases pressure in the lines. Open the fuel filler cap to release tank vapor pressure, then disconnect the negative battery cable.

Step 2: Drain the Fuel Tank

Siphon as much fuel as possible using a proper transfer pump. Never siphon by mouth. A nearly empty tank is much easier and safer to lower.

Step 3: Access the Fuel Pump

The 2014 Ford Taurus does not have an interior access panel under the rear seat. You must lower the fuel tank. Place a jack with a block of wood under the tank to support it.

Step 4: Remove the Fuel Tank Straps

Disconnect the filler tube hose, electrical connector, and EVAP hoses. Remove the retaining straps or bolts holding the tank to the frame. Slowly lower the tank just enough to access the pump module.

Step 5: Remove the Old Fuel Pump Assembly

The fuel pump module is held in place by a lock ring. Use a brass punch and hammer to loosen it—never use steel tools to avoid sparks. Lift the old pump assembly straight out, being careful not to bend the float arm.

Step 6: Install the New Fuel Pump

Compare the new KEMSO pump to the old one to verify fitment. Install a new O-ring seal on the tank opening. Insert the new pump assembly straight down, align it correctly, and tighten the lock ring to manufacturer torque spec (typically 30–40 ft-lbs). Reconnect all fuel lines, electrical connectors, and EVAP hoses.

Step 7: Reinstall the Fuel Tank

Lift the tank back into position, reinstall the straps, and reconnect the filler tube and electrical connector. Tighten strap bolts to spec.

Step 8: Prime the System and Test

Fill the tank with at least 2–3 gallons of fuel. Turn the key to ON for 2–3 seconds, then OFF. Repeat 3–4 times to prime the pump. Start the engine and let it idle. Check for fuel leaks, listen for unusual noises, and verify the engine runs smoothly. Take a road test to confirm full power restoration.

Cost to Replace a Fuel Pump on a 2014 Ford Taurus

The average cost for a Ford Taurus fuel pump replacement at a shop is between $1,015 and $1,286, including parts and labor. The pump module itself costs $100–$500, and labor (tank drop) runs $300–$700. If you DIY, you save the labor cost and only pay for the pump (typically $80–$200). Always replace the fuel filter and strainer at the same time—they are often the root cause of the original pump failure.

Common Mistakes to Avoid During Fuel Pump Replacement

  • Reusing the old O-ring – Always install a new seal to prevent leaks.
  • Using steel tools on the lock ring – Sparks can ignite fuel vapors. Use brass or nylon tools.
  • Not replacing the fuel filter – On the 2014 Taurus, the filter is built into the module. If you replace only the pump, the old filter will clog again.
  • Forgetting to prime the system – Starting the engine without priming can damage the new pump.
  • Tightening the lock ring by feel – Use a torque wrench to avoid damaging the seal or causing leaks.

Final Thoughts

A failing fuel pump on your 2014 Ford Taurus is not something to ignore. It can leave you stranded, cause engine damage, and create a safety hazard if it stalls suddenly on the highway. By diagnosing the symptoms early and following this guide, you can replace the pump yourself or confidently take it to a shop.
