2013 Ford F150 Fuel Pump: Complete Guide to Symptoms, Replacement, and Best Options
Understanding the 2013 Ford F-150 Fuel Pump System
The 2013 Ford F-150 uses an in-tank electric fuel pump that is integrated into a module assembly that also includes the fuel level sender, fuel pressure regulator, and fuel strainer. This module is mounted inside the fuel tank and delivers fuel at high pressure to the fuel injection system. The fuel pump module is accessed from the top of the fuel tank after the tank is lowered or removed from the vehicle.
Different engine configurations in the 2013 F-150 use different fuel pump assemblies. The 3.5L V6 EcoBoost engine uses a specific pump assembly with part numbers like BL3Z-9350-D or BL3Z-9350-A, while the 5.0L V8 and 6.2L V8 engines use a sender and pump assembly with part number 9L3Z-9H307-F. The 2.7L EcoBoost engine introduced in later years uses part number FL3Z9H307L. It is critical to select the correct pump assembly for your specific engine and drivetrain configuration.
Common Symptoms of a Failing Fuel Pump
Recognizing the early warning signs of a failing fuel pump can prevent you from being stranded on the road. Here are the most common symptoms to watch for:
1. Engine Hard Starting or No Start Condition
The most common symptom of a bad fuel pump is difficulty starting the engine. If the pump cannot build adequate fuel pressure, the engine may crank for an extended period before firing, or it may not start at all. This happens because the fuel injection system requires a minimum pressure to properly atomize fuel for combustion.
2. Engine Stalling While Driving
A failing fuel pump may intermittently lose the ability to maintain consistent fuel pressure, causing the engine to stall unexpectedly. This is particularly dangerous when driving at highway speeds. The stalling occurs because the pump's internal components wear out and cannot sustain the required fuel flow.
3. Loss of Power Under Load or Acceleration
When you press the accelerator, the engine demands more fuel. A weak fuel pump cannot keep up with this demand, resulting in hesitation, sputtering, or a complete lack of power during acceleration. This symptom is often more noticeable when climbing hills or carrying heavy loads.
4. Whining Noise from the Fuel Tank
A properly functioning fuel pump produces a low hum when operating. If you hear a loud whining or buzzing noise coming from the rear of the truck near the fuel tank, the pump bearings may be wearing out. This noise often becomes more pronounced as the fuel level drops.
5. Check Engine Light Illuminated
Many fuel pump issues will trigger diagnostic trouble codes related to fuel pressure or fuel system performance. Common codes include P0087 (Fuel Rail/System Pressure Too Low) and P0231 (Fuel Pump Secondary Circuit Low). A professional scan tool can read these codes to confirm the issue.

Step-by-Step Fuel Pump Replacement Guide
Replacing the fuel pump on a 2013 Ford F-150 requires careful preparation and adherence to safety procedures. Warning: Gasoline is extremely flammable, so take extra precautions when working on any part of the fuel system.
Tools and Materials You Will Need
- Socket set (10mm, 13mm, 15mm sockets)
- Ratchet and extension bar
- Torque wrench
- Fuel line disconnect tool set
- Fuel pump lock ring removal tool
- Floor jack and jack stands
- Transmission jack or wide jack pad
- Drain pan for fuel
- Safety goggles and nitrile gloves
- Shop towels
- Fire extinguisher rated for flammable liquids
- New fuel pump module assembly
- New O-ring seal for the fuel pump module
- New fuel tank strap bolts (recommended)
Step 1: Relieve Fuel System Pressure
Before disconnecting any fuel lines, you must relieve the pressure in the fuel system. Start by removing the fuel pump fuse or relay from the underhood fuse box. Start the engine and let it run until it stalls. Then crank the engine for about five more seconds to bleed off any remaining pressure. Turn the ignition key to the Off position and disconnect the negative battery cable using a wrench.
Step 2: Raise and Support the Vehicle
Use a floor jack to lift the rear of the truck and support it securely on jack stands placed under the frame rails. Leave enough clearance to lower the fuel tank safely. Make sure the vehicle is stable before working underneath it.
Step 3: Remove the Fuel Filler and Vent Connections
Using a 10mm socket, remove the fuel filler neck shield or retaining hardware if your truck is equipped with them. Loosen the filler neck and vent hose connections. Disconnect any hoses or clamps attached to the tank area.
Step 4: Disconnect Electrical and Fuel Lines
Use a fuel line disconnect tool set to release the fuel supply and return lines from the top of the tank. Unplug the fuel pump electrical connector from the tank harness. Keep shop towels ready for small fuel spills that may occur during disconnection.
Step 5: Support the Fuel Tank
Place a transmission jack or a floor jack with a wide pad under the fuel tank. Raise the jack until it supports the tank evenly without crushing it. Never use a small jack pad that could puncture the tank.
Step 6: Remove the Fuel Tank Straps
Using a 15mm socket and ratchet, remove the tank strap bolts. Lower the straps carefully and keep track of their position for reinstallation. During reassembly, tighten fuel tank strap bolts to 41 Nm (30 ft-lbs).
Step 7: Lower the Fuel Tank
Lower the tank slowly just enough to reach the top of the module. Check for any remaining hoses, clips, or wiring before lowering further. Once the tank is clear of the vehicle frame, remove it from under the truck and place it on a stable, flat surface.
Step 8: Remove the Fuel Pump Module
Clean the top of the fuel tank thoroughly before opening it to prevent debris from falling into the tank. Use the fuel pump lock ring removal tool to turn the retaining ring counterclockwise until it is loose. A special tool designed for this purpose is available, but large pliers or a hammer and brass punch can also work. Warning: If using a punch, use only a brass punch to avoid creating sparks.
Once the retaining ring is removed, lift the fuel pump module straight out of the tank. Be careful not to bend the fuel level float arm. Remove and discard the old O-ring seal from the tank opening.
Step 9: Install the New Fuel Pump Module
Apply a thin coat of clean engine oil to the new O-ring seal to hold it in place during assembly. Place the new seal in the tank opening. Lower the new fuel pump module into the tank in the same orientation as the old one. Align the marks on the module and tank before tightening the retaining ring. Use the lock ring tool to install and fully seat the retaining ring, turning it clockwise until it is tight.
Step 10: Reinstall the Fuel Tank
Lift the fuel tank back into position under the vehicle. Reconnect the fuel lines and vapor lines, making sure the quick-connect fittings click securely into place. Plug in the fuel pump module electrical connector. Raise the fuel tank fully into its mounting position and install the tank straps. Tighten the strap bolts to 41 Nm (30 ft-lbs) using a torque wrench.
Install the fuel filler neck and vent connections. If your truck has a fuel tank shield, reinstall it using the ratchet and socket. Lower the vehicle from the jack stands and reconnect the negative battery cable.
Step 11: Test the System for Leaks and Proper Operation
Plug the electrical connector located on the frame rail underneath the driver side door. Attach the splash shield to the frame rail. Turn the ignition key to the On position for three seconds to let the fuel system build pressure. Then turn the key to the Off position. Repeat this cycle three times to make sure the system has enough pressure. Start the engine and check for any fuel leaks around the tank and fuel line connections.
Listen for the fuel pump priming cycle when you first turn the key on. With the engine running, monitor for a stable idle and smooth acceleration response. If the vehicle stalls or hesitates, cycle the key on and off three to four times to repressurize the system and eliminate any air pockets in the fuel lines.

Safety Tips for Fuel Pump Replacement
Working with gasoline requires strict safety measures to prevent fires and injuries. Follow these essential safety tips throughout the replacement process:
Work in a Well-Ventilated Area: Fuel vapors are heavier than air and can accumulate in enclosed spaces. Always work outdoors or in a garage with the doors fully open. If you smell strong fuel vapors, stop working and allow the area to air out before continuing.
Disconnect the Battery: Before doing any work on the fuel system, disconnect the negative battery cable. This prevents any electrical sparks that could ignite fuel vapors. Keep the cable disconnected until the entire repair is complete and all connections are secure.
Keep a Fire Extinguisher Nearby: Have a fire extinguisher rated for Class B flammable liquid fires within easy reach. You should never use water to extinguish a fuel fire, as it can spread the flames.
Avoid Open Flames and Sparks: Do not smoke, use welding equipment, grind metal, or use any open flames near the vehicle during fuel system work. Use non-sparking tools when possible, especially when working near the fuel tank opening.
Properly Dispose of Old Fuel: If you need to drain the fuel tank, collect the fuel in an approved container and dispose of it at a local recycling center or hazardous waste facility. Never pour gasoline down drains or onto the ground.
Preventing Future Fuel Pump Problems
Once you have installed a new fuel pump, taking preventive measures can extend its service life and prevent premature failure.
Keep Your Fuel Tank at Least Quarter Full: Running the tank low on fuel frequently can cause the pump to overheat because the fuel surrounding it acts as a coolant. Maintaining at least a quarter tank of fuel helps keep the pump cool and lubricated.
Replace the Fuel Filter Regularly: A clogged fuel filter forces the pump to work harder, increasing wear on the internal components. Check your owner manual for the recommended replacement interval, which is typically every 30,000 to 50,000 miles.
Use Quality Fuel: Using fuel from reputable stations with proper filtration helps prevent contaminants from entering the fuel system. Poor quality fuel can contain water, dirt, and other debris that can damage the pump over time.
Address Check Engine Lights Promptly: If your check engine light comes on, have the diagnostic codes read as soon as possible. Many fuel system issues can be caught early before they cause permanent damage to the pump.
By following these guidelines and choosing a high-quality replacement pump like KEMSO, you can keep your 2013 Ford F-150 running reliably for many more miles. Remember to visit https://www.kemsoracing.com/ for KEMSO fuel pumps backed by a lifetime warranty and superior performance.
