2013 Ford Explorer Fuel Pump: Complete Guide to Symptoms, Replacement Cost, and Best Replacement Options
If you own a 2013 Ford Explorer with the 3.5L V6 engine and your vehicle is experiencing hard starting, stalling, loss of power during acceleration, or a whining noise from the fuel tank area, the fuel pump is likely failing. The total cost to replace the fuel pump on a 2013 Ford Explorer typically ranges from $600 to $1,200 if you hire a professional mechanic, with the fuel pump module itself costing between $81 and $200 for a quality aftermarket part. For owners who want to save money, a DIY replacement is entirely possible and can be completed in 3 to 6 hours with basic mechanical skills. This guide will walk you through the symptoms, diagnosis, replacement options, and the best fuel pump choices for your 2013 Ford Explorer.
Recognizing the Symptoms of a Failing Fuel Pump
The fuel pump in your 2013 Ford Explorer is responsible for delivering gasoline from the tank to the engine at the correct pressure and volume. When it starts to fail, you will notice several warning signs. Early detection is key to avoiding being stranded on the road.
Difficulty Starting is often the first and most noticeable symptom. The engine may crank for an extended period before finally starting, or it may not start at all, especially after the vehicle has been sitting for a while. This happens because the pump is struggling to build sufficient fuel pressure in the fuel rail .
Sudden Stalling is another common indicator. The engine may stall unexpectedly while driving, particularly at low speeds, when idling at a stoplight, or during stop-and-go traffic. This occurs when the pump cannot maintain a consistent fuel supply to the engine .
Loss of Power During Acceleration is a serious safety concern. When you press the gas pedal, the engine may hesitate, hesitate, or feel sluggish. This is caused by insufficient fuel delivery under load, which means the pump cannot keep up with the engine's demand for fuel when you need power most .
Whining or Buzzing Noise from the Fuel Tank is a clear mechanical warning. When you turn the ignition key to the "on" position, you should hear a brief humming sound from the rear of the vehicle as the fuel pump primes. If this sound becomes louder, more persistent, or turns into a whining noise, it indicates the pump's internal components are wearing out .
Check Engine Light may illuminate on your dashboard. While this can be caused by many issues, a failing fuel pump often triggers diagnostic trouble codes related to fuel system pressure or lean fuel mixture. Common codes include P0087 (Fuel Rail/System Pressure Too Low) or P0171 (System Too Lean) .
Rough Idle and Poor Fuel Economy are secondary symptoms. An inconsistent fuel supply can cause the engine to idle roughly or vibrate excessively. You may also notice a drop in miles per gallon, as the engine compensates for low fuel pressure by running inefficiently .
Diagnosing the Problem Before You Replace
Before you spend money on a new fuel pump, it is important to confirm that the pump is the actual problem. Other components like a clogged fuel filter, a bad fuel pump relay, or a faulty fuel pressure regulator can cause identical symptoms.
Listen for the Prime Sound is the easiest test. Turn the ignition key to the "on" position without starting the engine. You should hear a brief humming sound from the rear of the vehicle for about two seconds. If you do not hear anything, the pump may not be receiving power, or the pump itself may be dead .
Check the Fuel Pump Relay and Fuse in the fuse box. Locate the fuel pump relay and fuse (refer to your owner's manual for the exact location). Check the fuse for continuity using a multimeter. If the fuse is blown, replace it with one of the same amperage. If the relay is suspected, try swapping it with a similar relay from a less critical system like the horn. If the fuel pump now works, the relay is the culprit .
Perform a Fuel Pressure Test is the most definitive diagnostic method. A mechanic can connect a fuel pressure gauge to the fuel rail on the engine to measure the pressure. On a 2013 Ford Explorer with the 3.5L V6 engine, the fuel pressure should be between 55 and 65 psi when the engine is running and at idle. If the pressure is below 50 psi, the fuel pump is likely failing .
Inspect the Fuel Filter is a good practice. A clogged fuel filter can restrict fuel flow and mimic the symptoms of a failing fuel pump. If your vehicle has a serviceable fuel filter, replace it first. It is inexpensive and often solves the problem. If you are replacing the fuel pump, it is strongly recommended to replace the fuel filter at the same time .
Replacement Cost Breakdown
The cost to replace the fuel pump on a 2013 Ford Explorer varies significantly depending on whether you do the job yourself or hire a professional.
Professional Repair Cost ranges from $600 to $1,200 for a complete fuel pump replacement. Independent shops typically charge between $350 and $850, while dealerships range from $650 to $1,200. Labor is the biggest expense because the fuel tank must be lowered to access the pump. Labor time is usually 3 to 6 hours. All-wheel-drive (AWD) models may cost more due to added complexity .
DIY Replacement Cost is much lower. A high-quality aftermarket fuel pump module for the 2013 Ford Explorer typically costs between $81 and $200. You will also need basic tools, safety equipment, and possibly a new fuel filter. The total DIY cost is usually under $250 .
OEM vs. Aftermarket Parts is an important decision. Genuine Ford OEM parts are the most expensive option, with the Ford part number DB5Z-9H307-C costing between $286 and $470. OEM parts offer guaranteed fit and factory warranty coverage. Aftermarket parts from brands like Spectra Premium, Delphi, Airtex, and Carter offer comparable quality at lower prices, ranging from $81 to $200. Many aftermarket pumps are built to OEM specifications and include the same components: pump, sending unit, float arm, and seal .
Why You Should Replace the Whole Module
The 2013 Ford Explorer uses a fuel pump module installed inside the fuel tank. This module includes the electric pump, fuel level sending unit, strainer, and internal hoses. It is strongly recommended to replace the entire module rather than just the pump .
Simplicity is a major advantage. The module is a single unit that drops in, making installation straightforward. You do not have to disassemble the old pump or try to fit a new pump into the old housing.
Reliability is improved because the strainer, sending unit, and internal parts wear out over time. Replacing only the pump may leave you with a failing sending unit later, which would require dropping the tank again.
Cost-Effective is the bottom line. The additional cost of the module is small compared to the labor required to drop the tank again. If you are paying a mechanic $400 to $800 in labor, you do not want to do the job twice.

Step-by-Step DIY Replacement Guide
Replacing the fuel pump on a 2013 Ford Explorer is a job that requires mechanical skill and attention to detail. Follow these steps carefully. The difficulty level is advanced, and the estimated time is 3 to 6 hours .
Safety Precautions are critical. Work in a well-ventilated area. Gasoline fumes are highly flammable. Keep a fire extinguisher nearby, rated for chemical and fuel fires. No smoking or open flames. Do not use any tools that create sparks near the fuel tank. Wear safety goggles and gloves. Gasoline can irritate your skin and eyes. Disconnect the battery negative terminal before proceeding to prevent electrical sparks .
Tools You Will Need include a floor jack and jack stands, a wood block to support the fuel tank, screwdrivers and pliers, a ratchet set and sockets, a fuel line disconnect tool for quick-connect fittings, penetrating oil for rusted bolts, a new fuel pump module, and a new fuel filter. A transmission jack is recommended for safely lowering the fuel tank .
Step 1: Relieve Fuel System Pressure. Locate the fuel pump fuse in the fuse box and remove it. Start the engine and let it run until it stalls. This relieves pressure in the fuel lines. Crank the engine a few more times to ensure all pressure is gone. Reinstall the fuse after the engine is off .
Step 2: Access the Fuel Pump. For the 2013 Ford Explorer, the fuel pump is accessed by dropping the fuel tank. You do not need to remove the bed or body panels. Drive the vehicle until the fuel tank is as close to empty as possible to make the tank lighter and safer to handle .
Step 3: Lower the Fuel Tank. Support the fuel tank with a floor jack and a wood block. Disconnect the fuel filler neck hose, vent hose, and electrical connector for the fuel pump. Remove the tank straps. Carefully lower the tank enough to access the top of the fuel pump module .
Step 4: Remove the Old Fuel Pump Module. Disconnect the fuel lines from the pump module. Use a brass punch and a non-sparking hammer to rotate the lock ring counterclockwise. Lift the old pump module out carefully. Remove the old seal ring from the tank opening .
Step 5: Install the New Fuel Pump Module. Install the new seal ring on the tank opening. Lower the new pump module into the tank in the same orientation as the old one. Install and lock the retaining ring fully. Torque to factory specification if available. Reconnect the fuel lines by pushing them onto the fuel pump assembly until they click into place .
Step 6: Reinstall the Fuel Tank. Raise the tank slowly and reconnect the fuel filler neck hose, vent hose, and electrical connector. Reinstall the tank straps. Lower the vehicle and reconnect the battery .
Step 7: Prime the Fuel System and Test. Turn the ignition key to the "on" position for two seconds, then turn it to "off." Repeat this cycling several times to prime the fuel system. Start the engine and check for any fuel leaks. If everything looks good, take the Explorer for a test drive to verify it runs properly .
Tips to Extend Your New Fuel Pump's Life
Once you install a new fuel pump, you can take simple steps to maximize its lifespan. These habits also help you avoid premature failure in your current pump.
Keep your tank at least a quarter full. The fuel pump relies on gasoline to cool and lubricate its internal components. Running the tank low frequently causes the pump to run hot and wear faster. Make it a habit to refill when the gauge hits one-quarter .
Use quality fuel from reputable stations. Cheap or contaminated fuel contains water, dirt, and other impurities that clog the pump strainer and damage the pump motor. Stick with major brands that maintain clean storage tanks .
Replace the fuel filter on schedule. If your vehicle has a serviceable fuel filter, change it every 30,000 miles or as recommended in your owner's manual. A clogged filter forces the pump to work harder .
Do not ignore warning signs. As soon as you notice hesitation, hard starting, or unusual noise, have the fuel system checked. Early intervention can save you from being stranded on the road.
Summary
A failing fuel pump in your 2013 Ford Explorer causes no-start, stalling, loss of power, whining noise, and check engine light. Replacement cost averages $600 to $1,200 at a shop, or $81 to $200 for DIY parts. Labor takes 3 to 6 hours, with AWD models costing more.
