2017 Ford Fusion Fuel Pump: Complete Guide to Symptoms, Replacement, and Cost

If you own a 2017 Ford Fusion and your engine is sputtering, hesitating, or struggling to start, the fuel pump is likely the culprit. The fuel pump on a 2017 Ford Fusion is located inside the fuel tank, and when it fails, the most reliable solution is to replace it with a high-quality unit that matches or exceeds OEM specifications. This guide covers everything you need to know about diagnosing a failing fuel pump, understanding replacement costs, and choosing the right replacement part for your Fusion.

Common Symptoms of a Failing Fuel Pump in a 2017 Ford Fusion

A fuel pump's job is straightforward: it pumps fuel from the tank to the engine at the correct pressure. When it starts to fail, your car will give you clear warning signs. Here are the most common symptoms to watch for:

1. Engine sputtering or hesitation at high speeds. If your Fusion feels like it's choking or struggling to maintain speed, especially when going uphill or carrying a load, the fuel pump may not be delivering enough fuel volume. The engine demands more fuel under load, and a weak pump simply can't keep up .

2. Whining noise coming from the fuel tank. A healthy fuel pump makes a quiet hum when you turn the key to the "ON" position. If you hear a loud, high-pitched whining sound coming from the rear of the car, especially near the fuel tank, the pump is likely wearing out. This noise means the pump is working harder than it should to push fuel through the system .

3. Hard starting or long cranking times. A failing fuel pump may not build enough pressure in the fuel system before you try to start the engine. This means you'll have to crank the engine longer than usual before it fires up. In some cases, the engine may not start at all .

4. Engine surging or bucking at steady speeds. If you're cruising on the highway and the car suddenly surges forward or bucks without you touching the gas pedal, the fuel pump could be delivering inconsistent fuel pressure. This erratic behavior is dangerous and should be addressed immediately .

5. Loss of power under acceleration. When you press the gas pedal, the engine should respond quickly. If you feel a noticeable lag or the car simply doesn't accelerate like it used to, the fuel pump may not be capable of supplying enough fuel to meet the demand .

6. Check Engine Light comes on. A failing fuel pump can trigger the Check Engine Light because the engine's computer detects low fuel pressure or a lean fuel mixture. If you see this light along with any of the symptoms above, have the system diagnosed as soon as possible .

Where Is the Fuel Pump Located on a 2017 Ford Fusion?

The fuel pump on a 2017 Ford Fusion is mounted inside the fuel tank. This is standard for modern vehicles because submerging the pump in fuel keeps it cool and reduces the risk of fire . To access the pump, you need to remove the rear seat cushion. Under the seat, there is a circular access panel or cover. Remove that panel, and you will find the fuel pump module directly on top of the fuel tank .

You will not find the fuel pump in the engine bay, trunk, or under the car. It is always inside the tank for this model year .

How Much Does a 2017 Ford Fusion Fuel Pump Replacement Cost?

Replacing the fuel pump on a 2017 Ford Fusion is not a cheap repair, primarily because of the labor involved. The fuel tank must be lowered or accessed through the interior, which takes time.

Parts cost: A new fuel pump module for the 2017 Ford Fusion typically ranges from $191 to $250 for a quality aftermarket or OEM replacement. For example, AutoZone lists TruGrade and Delphi fuel pump modules for the 2017 Fusion between $191.99 and $249.99 . Higher-end parts can go up to $509.99 depending on the brand and features .

Labor cost: The labor to replace the fuel pump is significant because the mechanic must relieve fuel system pressure, remove the rear seat, disconnect fuel lines and electrical connectors, remove the locking ring, and carefully extract the pump assembly from the tank. This process typically takes 2 to 4 hours. At a shop rate of $100 to $150 per hour, labor alone can run $200 to $600.

Total estimated cost: According to Kelley Blue Book, the average national cost for a fuel pump replacement on a 2017 Ford Fusion is between $1,263 and $1,464 . This includes both parts and labor. RepairPal gives a similar national average of $981 to $1,232 for the Ford Fusion across various model years .

Can You Replace the Fuel Pump Yourself?

Replacing the fuel pump on a 2017 Ford Fusion is a challenging but doable DIY project for someone with intermediate mechanical skills and the right tools. The process involves relieving fuel system pressure, removing the rear seat, disconnecting fuel lines, removing the locking ring, and lifting the pump module out of the tank .

Safety considerations are critical. You are working with gasoline, which is highly flammable. Always work in a well-ventilated area away from any open flames, sparks, or pilot lights. Disconnect the negative battery cable before starting. Wear safety glasses and gloves. Have a fire extinguisher rated for fuel fires nearby .

The basic steps are:

1. Relieve fuel system pressure by removing the fuel pump relay or fuse, then starting the engine and letting it run until it stalls .
2. Disconnect the negative battery cable.
3. Remove the rear seat cushion to access the fuel pump access panel.
4. Remove the access panel and disconnect the electrical connector and fuel lines from the pump module .
5. Remove the locking ring using a special tool or a hammer and punch.
6. Carefully lift the fuel pump module out of the tank. Be prepared for some fuel spillage .
7. Transfer any necessary components from the old module to the new one, such as the fuel level sending unit or fuel filter, if they are not included with the new pump .
8. Install the new pump module, secure it with the locking ring, reconnect the fuel lines and electrical connector, and reinstall the access panel and rear seat.
9. Reconnect the battery, turn the ignition to the ON position, and check for fuel leaks. Start the engine and verify proper operation .

If you are not comfortable with any of these steps, it is best to leave the job to a professional mechanic. A mistake during fuel system repair can lead to a dangerous fuel leak or fire.
