2016 Ford Explorer Fuel Pump Replacement: A Complete DIY Guide

Replacing the fuel pump on a 2016 Ford Explorer is an advanced DIY job that involves dropping the fuel tank, and it typically costs between $900 and $1,600 at a professional shop. If you do it yourself, the parts cost ranges from $250 to $700, and you can save between $650 and $900 by completing the repair on your own . The job requires 4 to 7 hours of labor, and you must relieve fuel system pressure, disconnect the battery, and work safely in a well-ventilated area away from sparks and flames .

Signs Your 2016 Ford Explorer Needs a New Fuel Pump

A failing fuel pump on a 2016 Ford Explorer will show clear symptoms. Here are the most common signs to watch for:

  1. Hard starting: The engine cranks but takes longer than usual to start, or it may not start at all .
  2. Hesitation and loss of power: The vehicle sputters or hesitates when accelerating, especially uphill or at highway speeds .
  3. Stalling: The engine may stall while driving, particularly when the fuel tank is low .
  4. Whining noise from the fuel tank: A loud, high-pitched whine coming from the rear of the vehicle indicates the pump is wearing out .
  5. Check engine light: The check engine light may come on with fuel system-related diagnostic trouble codes .

Important: If you experience any of these symptoms, do not continue driving the vehicle. A bad fuel pump can leave you stranded and may cause damage to other fuel system components .

Cost of Replacing a Fuel Pump on a 2016 Ford Explorer

The total cost varies depending on whether you do the work yourself or hire a professional:

  • Professional shop cost: $900 to $1,600, which includes both parts and labor. Labor rates typically range from $100 to $150 per hour, and the job takes a shop approximately 3 to 6 hours .
  • DIY cost: $250 to $700, which covers the cost of the fuel pump module and related parts. You save $650 to $900 by doing the job yourself .

Parts You Will Need

For a 2016 Ford Explorer fuel pump replacement, you will need these parts:

  • Fuel pump module assembly: This is the complete in-tank unit that includes the pump, fuel level sender, and strainer .
  • Fuel tank seal ring/O-ring: Always replace this seal to prevent fuel leaks and fuel odor inside the cabin .
  • Fuel filter sock: The strainer attached to the pump pickup should be replaced with the new pump.
  • Fuel line O-rings and seals: These small seals help prevent leaks at the fuel line connections .
  • Fuel tank straps: If the original straps are rusted or corroded, replace them at the same time .

Tools Required for the Job

Before starting, gather the following tools:

  • Fuel line disconnect tool set: This specialty tool is required to release the quick-connect fittings on the fuel lines without damaging them .
  • Socket set (8mm to 18mm): For removing the battery cable, tank straps, and underbody shields .
  • Torque wrench: To tighten the tank strap bolts to the correct specification of 48 Nm (35 ft-lbs) .
  • Transmission jack or wide-support floor jack: The fuel tank is heavy and awkward, so you need a sturdy jack to support and lower it safely .
  • Jack stands (rated for vehicle weight): Always support the vehicle securely before working underneath it .
  • Brass drift punch and non-sparking hammer: Used to tap the fuel pump lock ring loose without creating sparks near fuel vapors .
  • Fuel-safe drain pan, shop rags, safety glasses, and nitrile gloves: Fuel will spill, so protect yourself and your work area .

Step-by-Step Replacement Process

Preparation

  1. Park on level ground and set the parking brake. Run the fuel tank as low as possible before starting. Less fuel makes the tank lighter and safer to lower .
  2. Disconnect the negative battery cable using an 8mm socket. Move the cable aside so it cannot touch the terminal .
  3. Relieve fuel system pressure. Use the fuse or relay method: remove the fuel pump fuse or relay, start the engine and let it idle until it stalls, then crank the engine for a few more seconds. Open the fuel filler cap carefully after pressure is relieved .

Removing the Fuel Tank

  1. Raise and support the vehicle using a floor jack and jack stands. Make sure the vehicle is stable before working underneath .
  2. Remove underbody shields and supporting components. Use a socket set to remove any splash shields that block access to the fuel tank. On AWD models, check for exhaust and driveshaft clearance .
  3. Support the fuel tank with a transmission jack or a wide-support jack. Raise it just enough to hold the tank securely. Never let the tank hang by the hoses or straps .
  4. Disconnect filler and vent hoses. Use a flat trim tool to release any clamps or retainers. Mark each connection so you can reinstall it correctly .
  5. Disconnect electrical connectors and fuel lines. Use the fuel line disconnect tool set to release the quick-connect fittings. Have a drain pan and shop rags ready for any fuel that spills. Cap or wrap open lines with clean rags to keep dirt out .
  6. Lower the fuel tank slowly using the transmission jack. Double-check that all hoses, connectors, and lines are free. Slide the tank out from under the vehicle .

Replacing the Fuel Pump Module

  1. Clean the area around the pump lock ring with shop rags to remove dust and debris. Mark the orientation of the module with a permanent marker so the new one goes in the same way .
  2. Remove the lock ring using a brass drift punch and hammer. Tap the lock ring counterclockwise until it releases. Lift the lock ring off and set it aside .
  3. Carefully lift the fuel pump module out of the tank. Angle the module as needed to clear the float arm. Remove the old tank seal/O-ring by hand .
  4. Install the new tank seal/O-ring into the tank opening. Make sure it is clean and fully seated .
  5. Lower the new fuel pump module into the tank. Keep the float arm from bending. Align the module using your orientation mark. Install the new lock ring and tap it clockwise with the brass drift punch until it is fully locked .

Reinstalling the Fuel Tank

  1. Slide the tank back under the vehicle and raise it using the transmission jack .
  2. Reconnect the fuel and vapor lines. Push the quick-connect fittings until you hear a solid click. Reconnect all electrical connectors .
  3. Reinstall the tank straps. Start the strap bolts by hand to prevent cross-threading. Torque the strap bolts to 48 Nm (35 ft-lbs) .
  4. Reinstall any underbody shields and lower the vehicle off the jack stands .

Priming the System and Testing

  1. Reinstall the fuel pump fuse or relay and reconnect the negative battery cable. Torque the battery terminal clamp to 7 Nm (62 in-lbs) .
  2. Prime the fuel system. Turn the key to the ON position (do not start) for 5 seconds, then turn it OFF for 5 seconds. Repeat this cycle 3 to 4 times to build fuel pressure .
  3. Start the engine and let it idle. Inspect for leaks around the tank area and fuel line connections. Take a short test drive, then recheck for leaks again .

Common Mistakes to Avoid

  • Forgetting to relieve fuel pressure: This is the most common mistake. If you disconnect a fuel line under pressure, you will get a face full of gasoline .
  • Using excessive force on the pump assembly: The fuel pump module is made of plastic and has delicate components. Do not pry on it or use excessive force to remove it .
  • Damaging the fuel level sender: The float arm on the fuel level sender is thin and bends easily. Handle the assembly gently .
  • Skipping the new O-ring: The O-ring that seals the fuel pump assembly to the tank is a wear item. Always replace it with a new one to prevent leaks and fuel odor inside the cabin .
  • Not labeling connections: Fuel lines and electrical connectors can look similar. Mark them before disconnecting to ensure correct reinstallation .

How to Extend the Life of Your New Fuel Pump

Once you install a new fuel pump, follow these maintenance practices to help it last as long as possible:

  • Never run the tank below a quarter full. When the fuel level is low, the pump is exposed to air and runs hotter, which accelerates wear. The fuel in the tank helps cool and lubricate the pump .
  • Use quality fuel from reputable stations. Poor-quality fuel contains more contaminants and impurities that can clog the pump strainer and damage internal components .
  • Replace the fuel filter regularly. A clogged fuel filter forces the pump to work harder, generating more heat and wear. Follow your manufacturer's recommended service intervals .
  • Keep your fuel system clean. Use a quality fuel system cleaner every 5,000 miles to remove deposits and prevent buildup that can restrict fuel flow .
  • Address check engine lights promptly. If your vehicle stores fuel system fault codes, have them diagnosed immediately. Small problems can become major repairs if ignored .

When to Call a Professional

Even if you are an experienced DIYer, there are situations where it is better to seek professional help:

  • If your vehicle requires extensive disassembly beyond what is described in this guide .
  • If the fuel tank is rusted, damaged, or contains excessive contamination that requires specialized cleaning .
  • If you encounter seized or rusted fasteners that you cannot safely remove .
  • If you do not have access to proper lifting equipment and jack stands for safely supporting the vehicle .
  • If you are uncomfortable working with fuel systems or have any doubts about your ability to complete the job safely .
