Symptoms of a Failing Fuel Delivery System
Before you commit to a 2016 ford explorer fuel pump replacement, you must verify that the pump is actually the culprit. Fuel systems are complex, and several components can mimic the signs of a bad pump. One of the most common signs is a high-pitched whining noise coming from the rear of the vehicle where the tank is located.
You might also experience “surging” while driving at a constant speed, which feels like the car is trying to speed up even when you haven’t pressed the gas. This happens because the pump is struggling to maintain a consistent flow of gasoline to the injectors. If the engine stalls under load, such as when climbing a hill or towing, the pump likely cannot meet the increased demand.
Check your dashboard for a “Check Engine” light; often, a failing pump will trigger lean codes like P0171 or P0174. Another classic symptom is a long cranking time before the engine finally fires up. This indicates that the check valve inside the pump assembly has failed, allowing fuel to drain back into the tank when the car is off.
Testing Fuel Pressure
The most scientific way to confirm a failure is to use a fuel pressure gauge. Attach the gauge to the Schrader valve on the fuel rail under the hood. For a 2016 Explorer, you should typically see pressure readings between 55 and 65 PSI, depending on your specific engine variant.
If the pressure is significantly lower than the manufacturer’s specification, the pump is likely worn out. However, always check the fuel pump fuse and the relay in the engine bay power distribution box first. A blown fuse is a much cheaper fix than a full pump assembly.
2016 ford explorer fuel pump replacement: Tools and Supplies Needed
Performing a 2016 ford explorer fuel pump replacement requires a specific set of tools to ensure the job is done correctly and safely. Because the fuel tank must be lowered on this model, you will need more than just a basic screwdriver set. Preparation is key to avoiding mid-project trips to the parts store.
- Floor Jack and Jack Stands: You need to lift the vehicle high enough to slide the fuel tank out from underneath.
- Fuel Line Disconnect Tools: These plastic or metal clips allow you to release the quick-connect fittings without damaging the lines.
- Socket Set: Specifically, you will need 10mm, 13mm, and 15mm sockets for the tank straps and heat shields.
- Brass Drift or Lock Ring Tool: Using a steel punch can create sparks near fuel vapors; a brass punch is much safer for removing the lock ring.
- Fuel Drain Jugs: It is much easier to drop a tank that is nearly empty. A full tank can weigh over 150 pounds.
- Safety Gear: Nitrile gloves and wraparound eye protection are non-negotiable when working with pressurized gasoline.
Choosing the Right Replacement Part
When buying your new pump, try to get the entire fuel pump assembly rather than just the motor. The assembly includes the sending unit (which controls your gas gauge), the internal filter, and the pressure regulator. Replacing the whole unit ensures you won’t have to drop the tank again in six months to fix a faulty level sensor.
Stick with reputable brands like Motorcraft, Bosch, or Delphi. While “no-name” parts on discount sites are tempting, the labor involved in this job makes reliability your top priority. You do not want to perform this repair twice because of a cheap component.
Safety First: Precautions Before You Start
Working on a fuel system is inherently dangerous due to the presence of flammable vapors. You must work in a well-ventilated area, preferably outdoors or in a garage with the door wide open. Never use a halogen work light, as the heat can ignite fumes; use LED lighting instead.
Keep a Class B fire extinguisher within arm’s reach at all times. Before you touch any fuel lines, disconnect the negative terminal of the battery. This prevents any accidental electrical sparks from the fuel pump wiring or other sensors while you are working near the open tank.
Relieve the fuel system pressure before disconnecting lines. You can do this by removing the fuel pump relay and cranking the engine until it stalls. This simple step prevents a high-pressure spray of gasoline from hitting your face when you pop the first connector loose.
Step-by-Step Guide to Dropping the Fuel Tank
On the 2016 Ford Explorer, there is no factory access panel under the rear seat. This means you must lower the fuel tank to perform a 2016 ford explorer fuel pump replacement. This is the most labor-intensive part of the process, but it is straightforward if you take your time.
- Drain the Tank: Use a siphon pump to remove as much gasoline as possible. If you can’t siphon it, you will need a second jack to balance the heavy tank as it comes down.
- Remove the Driveshaft (AWD Models): If your Explorer is All-Wheel Drive, the driveshaft may obstruct the tank. Mark the orientation of the shaft before removing the bolts so you can reinstall it without causing vibrations.
- Disconnect the Filler Neck: Loosen the hose clamps on the rubber hose connecting the gas cap area to the tank. Carefully pull the hose off the tank inlet.
- Support the Tank: Place a floor jack with a wide block of wood under the center of the tank to distribute the weight.
- Unbolt the Straps: Remove the bolts holding the metal straps in place. Once the straps are hanging, slowly lower the jack a few inches.
Disconnecting Lines and Electrical Plugs
Do not drop the tank all the way to the ground immediately. Lower it just enough to reach your hand over the top. You will need to disconnect the electrical harness and the main fuel supply and return lines. These usually feature “push-to-release” tabs.
Be careful with the evaporative emission (EVAP) lines. These plastic lines can become brittle over time and are prone to snapping. If a connector feels stuck, spray it with a bit of silicone lubricant to help the O-rings slide off without tearing.
Replacing the Pump Assembly
With the tank on the ground, clean the top surface thoroughly. Use compressed air or a brush to remove all dirt, sand, and debris. If any of this grime falls into the tank while the pump is out, it can clog your new pump or damage your fuel injectors down the line.
Use your brass drift and a hammer to rotate the metal lock ring counter-clockwise. Once the ring is removed, carefully lift the old pump assembly out of the tank. Be prepared for some fuel to drip out of the unit; have a bucket or drain pan ready to catch it.
Compare the old pump to the new one to ensure they are identical. Before dropping the new unit in, verify that the new O-ring seal is seated perfectly in the tank groove. A pinched seal will cause a “Large Leak” EVAP code and a persistent smell of raw gasoline around your car.
Installing the New Lock Ring
Place the new pump into the tank, paying attention to the orientation of the fuel ports. Most assemblies have an alignment tab that fits into a notch on the tank. Press down firmly and slide the lock ring back into place, rotating it clockwise until it is fully seated against the stops.
Double-check the electrical pins on the new pump. Ensure they are straight and clean before you lift the tank back into position. A bent pin during installation will result in a “no-start” condition, forcing you to repeat the entire labor process.
Reinstalling the Tank and Final Checks
Lift the tank back into position using your floor jack. As you rise, reconnect the fuel lines and the electrical harness. You should hear a distinct click when the fuel lines are properly seated. Tug on them gently to ensure they won’t blow off under pressure.
Reinstall the tank straps and tighten the bolts to the manufacturer’s torque specifications. Reconnect the filler neck hose and ensure the hose clamp is tight. If you removed the driveshaft or any heat shields, bolt those back into place now.
Reconnect the battery and turn the ignition key to the “ON” position without starting the engine. You should hear the fuel pump prime for about two seconds. Do this three or four times to build pressure in the lines and purge any air from the system.
Checking for Leaks
Start the engine and let it idle. While it is running, look under the vehicle for any signs of dripping fuel. If everything looks dry, take the vehicle for a short test drive. Pay attention to the responsiveness of the throttle and ensure the gas gauge is reading correctly.
A successful 2016 ford explorer fuel pump replacement should result in a smooth idle and immediate throttle response. If the vehicle still struggles, you may need to investigate the Fuel Pump Driver Module (FPDM), which is a common failure point on Ford vehicles of this era.
Frequently Asked Questions About 2016 Ford Explorer Fuel Pump Replacement
How long does it take to replace the fuel pump?
For an experienced DIYer with the right tools, the job typically takes between 3 and 5 hours. If you are working on the ground with jack stands, expect it to take a bit longer due to the limited space for maneuvering the tank.
Can I replace the fuel pump without dropping the tank?
Technically, no. The 2016 Ford Explorer does not have a factory-made access door. While some owners choose to cut a hole in the floorboard under the rear seat, this is generally not recommended as it can compromise the structural integrity of the vehicle and create a fire hazard if not sealed correctly.
Why did my fuel pump fail so early?
Fuel pumps are cooled by the gasoline surrounding them. Frequently running your tank below a quarter-full can cause the pump to overheat. Additionally, contaminated fuel or a clogged internal filter can put extra strain on the motor, leading to premature failure.
Do I need to replace the fuel filter too?
On the 2016 Explorer, the fuel filter is integrated into the fuel pump assembly. By replacing the entire module, you are automatically installing a fresh filter. There is no external, inline filter that requires separate maintenance on this model year.
What is the average cost of this repair at a shop?
A professional 2016 ford explorer fuel pump replacement usually costs between $800 and $1,200, including parts and labor. By doing it yourself, you can save several hundred dollars in labor costs, often spending only $200 to $400 on a high-quality pump assembly.
Final Thoughts on Fuel System Maintenance
Completing a 2016 ford explorer fuel pump replacement is a significant achievement for any DIY mechanic. It requires patience, the right tools, and a strict adherence to safety protocols. Once the job is done, you will have the peace of mind that comes with a reliable fuel delivery system.
To extend the life of your new pump, try to keep your fuel level above a quarter tank at all times. This keeps the pump motor submerged and cool. Also, stick to high-quality fuel stations to minimize the amount of sediment entering your tank.
