1999 Ford Taurus Fuel Pump Location: Where to Find It and How to Replace It

The fuel pump on a 1999 Ford Taurus is located inside the fuel tank, mounted as part of the fuel pump module assembly at the top of the tank . This is the standard location for nearly all modern vehicles, including the Taurus, and it means you cannot access the pump from outside the tank without either dropping the tank or cutting an access hole. If you are experiencing symptoms like stalling, loss of power, or a no-start condition, the fuel pump is often the culprit, and knowing its exact location is the first step toward a successful repair.

Understanding the 1999 Ford Taurus Fuel System

The fuel system in your 1999 Ford Taurus is a returnless, electric fuel injection system. The fuel pump is an electric motor-driven device that draws fuel from the tank and pushes it to the engine at a regulated pressure, typically around 30-45 psi. The pump is integrated into a module that also includes the fuel level sending unit (which tells you how much gas is in the tank) and a fuel filter strainer at the bottom.

Why the Fuel Pump is Inside the Tank

Car manufacturers, including Ford, place the fuel pump inside the tank for several reasons:

  • Cooling: The fuel in the tank helps cool the electric pump motor, preventing overheating.
  • Lubrication: The fuel itself lubricates the pump's internal components.
  • Safety: Placing the pump in the tank reduces the risk of fuel leaks in the event of a crash, since the pump is isolated from the passenger compartment.

This design is reliable, but it makes replacement more labor-intensive because you must physically access the interior of the tank.

How to Actually Access the Fuel Pump on a 1999 Ford Taurus

There are two main methods to reach the fuel pump: dropping the fuel tank or cutting an access hole in the trunk floor. Both are common, but the method you choose depends on your skill level, tools, and comfort with fuel system work.

Method 1: Dropping the Fuel Tank (The Standard Procedure)

This is the method recommended by most repair manuals and professional mechanics. It involves removing the fuel tank from the vehicle to access the pump module from the top.

Step-by-step overview:

  1. Relieve fuel system pressure: Remove the fuel pump relay from the fuse box, start the engine, and let it run until it stalls. Then crank the engine for a few seconds to purge any remaining pressure .
  2. Disconnect the battery: Remove the negative battery cable to prevent electrical sparks .
  3. Drain the fuel tank: Use a hand siphon pump to drain the tank to at least 1/4 full or less. This makes the tank lighter and easier to handle .
  4. Raise the vehicle: Safely lift the rear of the Taurus using a floor jack and support it on two jack stands. Chock the front wheels .
  5. Disconnect fuel lines and electrical connector: Locate the three quick-connect couplings at the top of the tank. Label them if needed for reassembly. Also, unplug the fuel pump electrical connector and disconnect the fuel filter inlet tube .
  6. Support and lower the tank: Place a floor jack with a wooden block under the fuel tank to support it. Then, unfasten the two fuel tank support straps using a ratchet and socket. Carefully lower the tank .
  7. Clean the pump area: Use a wire brush and rag to clean the top of the fuel pump module. This prevents dirt from falling into the tank when you remove the pump .
  8. Remove the pump module retaining ring: Use a special tool (Ford tool number 310-D006 or a suitable retaining ring remover) to unscrew the locking ring counterclockwise. You can also use a hammer and a brass punch to gently tap the ring loose .
  9. Lift out the pump module: Carefully pull the pump module straight up out of the tank. Be aware that it may have fuel residue inside, so have a rag ready .

Method 2: Cutting an Access Hole (Alternative for DIYers)

Some owners choose to cut an access panel in the trunk floor to avoid dropping the tank. This is a shortcut, but it requires careful measurement and cutting. The access hole is typically cut directly above the fuel pump location, which is on the passenger side of the trunk floor, under the carpet .

Important:

  • Use metal snips or a manual saw to avoid sparks from power tools. Fuel vapors can ignite easily .
  • After cutting, you can reach the fuel pump retaining ring and remove it without lowering the tank.
  • You must create a cover plate to seal the hole afterward to prevent fumes from entering the cabin.

Many mechanics advise against this method because it can weaken the vehicle's structure and create a potential leak path for fumes.

Recommended Parts for the 1999 Ford Taurus Fuel Pump

When replacing the fuel pump, you have two main choices: an OEM (Original Equipment Manufacturer) replacement or a high-performance aftermarket pump. For a 1999 Ford Taurus, a standard OEM-style replacement is sufficient for daily driving. However, if you want a pump that is more durable, offers better flow, and comes with a lifetime warranty, you should consider a high-performance option.

Common Symptoms of a Bad Fuel Pump on a 1999 Ford Taurus

Before you start replacing the pump, it is important to confirm it is actually the problem. Here are the most common signs that the fuel pump is failing:

  • Engine cranks but won't start: This is the most obvious symptom. The pump is not delivering fuel to the engine.
  • Loss of power under load: The car may struggle to accelerate or feel sluggish, especially when going uphill or carrying a heavy load.
  • Sputtering or stalling: The engine may cut out intermittently, especially at high speeds or when the fuel tank is low. This happens because the pump is not maintaining consistent pressure.
  • Whining noise from the fuel tank: A healthy fuel pump makes a low hum. If you hear a loud, high-pitched whine coming from the rear of the car, the pump is likely wearing out .
  • Check engine light: A failing fuel pump can trigger the check engine light, often with a code related to fuel system pressure or lean fuel mixture.

DIY vs. Professional Replacement: What You Should Know

Replacing a fuel pump on a 1999 Ford Taurus is a challenging but doable job for a home mechanic with moderate experience. The cost of the pump itself ranges from $100 to $300 for a quality aftermarket unit like KEMSO, while labor at a shop can add $500 to $1,000 or more .

If you decide to do it yourself:

  • Safety first: Fuel is extremely flammable. Work in a well-ventilated area, away from open flames or sparks. Keep a fire extinguisher nearby .
  • Use the right tools: You will need a fuel line disconnect tool, a retaining ring tool (or hammer and punch), and a jack to support the tank .
  • Take your time: Dropping the tank is the hardest part. Be patient with the fuel lines and straps.

If you choose a professional:

  • Expect to pay: In 2025, the total cost for a fuel pump replacement at a shop is typically between $916 and $1,165, with labor costing $161 to $203 and parts costing $755 to $962 .
  • Get a warranty: Most shops offer a warranty on parts and labor, which can save you money if something goes wrong later.

Final Thoughts

Finding the fuel pump on a 1999 Ford Taurus is straightforward: it is inside the fuel tank. Replacing it requires either dropping the tank or cutting an access hole, both of which are significant tasks. If you are comfortable with mechanical work and have the right tools, you can save a lot of money by doing the job yourself. Just remember to take all necessary safety precautions, including disconnecting the battery and relieving fuel pressure.
