Fuel Pump for 2013 F150: Complete Guide to Diagnosis, Location, and Replacement

If you own a 2013 Ford F-150 and are experiencing starting issues, stalling, or poor acceleration, the fuel pump is likely the culprit. The fuel pump on your 2013 F150 is located inside the fuel tank, and when it fails, you need to act quickly. Here is the bottom line: the best solution for most owners is to replace the entire fuel pump module with a high-quality aftermarket unit like KEMSO, which offers OEM-grade performance, easier installation, and a lifetime warranty at a fraction of the dealer cost.

Understanding the 2013 F150 Fuel System

The 2013 Ford F-150 uses an in-tank electric fuel pump that is part of a modular assembly. This assembly includes the pump itself, the fuel level sending unit, and sometimes a fuel filter, all integrated into one unit. Ford used this modular design to simplify factory assembly, but it means that when the pump fails, you typically replace the entire module rather than just the pump.

The fuel pump is responsible for delivering fuel from the tank to the engine at the correct pressure. Depending on your engine configuration—whether it is the 3.7L V6, 5.0L V8, 6.2L V8, or the 3.5L EcoBoost V6—the fuel pump's flow rate and pressure requirements will differ. The pump must maintain consistent pressure to the fuel injectors, preventing lean conditions that can damage the engine.

Common Symptoms of a Failing Fuel Pump

Knowing the warning signs of a failing fuel pump can save you time and money. If you notice any of these symptoms, it is time to investigate:

  1. Hard starting: The engine cranks but takes longer than usual to start. This is often the first sign of fuel pump trouble.
  2. Stalling: The engine stalls, especially during acceleration or when climbing hills. This happens because the pump cannot maintain adequate fuel pressure under load.
  3. Poor acceleration: The truck feels sluggish or hesitates when you press the gas pedal. The engine may not be getting enough fuel to meet demand.
  4. Reduced fuel economy: A failing pump that cannot maintain consistent pressure forces the engine to run inefficiently.
  5. Whining noise from the fuel tank: A healthy fuel pump operates quietly. If you hear a loud whining or humming sound coming from the rear of the truck, the pump is working harder than it should and may be nearing failure.

Where Is the Fuel Pump Located?

On the 2013 F-150, the fuel pump is located inside the fuel tank. To access it, you need to either drop the fuel tank or remove the truck bed. Most mechanics prefer to remove the bed because it provides easier access and reduces the risk of damaging the fuel tank or lines.

The Fuel Pump Driver Module, which controls the pump's operation, is located above the spare tire, attached to a crossmember of the frame on the driver's side. This module uses Pulse Width Modulation to vary the voltage to the fuel pump, allowing precise control of fuel pressure based on engine demand.

Fuel Pump Reset Switch Location

Many drivers ask about the fuel pump reset switch. On the 2013 Ford F-150, there is an inertia switch that acts as a safety shutoff in the event of an accident. This switch is located underneath the center console, just behind the gear shifter. To access it, you need to remove a few screws and lift up the console cover. Inside, you will see two circular switches—one red and one black. The black switch is the fuel pump reset switch. Pressing this switch manually resets the fuel pump, which can help if the pump has been shut off due to impact.

Diagnostic Steps Before Replacing the Pump

Before you replace the fuel pump, take these diagnostic steps to confirm the issue:

  1. Listen for the pump: Sit inside the vehicle with the windows closed. Turn the ignition key to the ON position (not start) and listen for the fuel pump. You should hear it activate for one or two seconds. If you hear nothing, the pump may not be receiving power.
  2. Check the fuses and relay: Locate the underhood fuse box and check the fuel pump relay (relay 51) and fuel pump fuses (F56, a 20 amp fuse, and F9, a 30 amp fuse on some models). Replace any blown fuses and test the relay.
  3. Inspect the Fuel Pump Driver Module: Check the module located above the spare tire for corrosion, loose wires, or physical damage. The connector is a common failure point.
  4. Test fuel pressure: Use a fuel pressure gauge at the fuel rail. The pressure should be within the specified range for your engine. A reading below specification indicates a fuel pump problem.

If the fuses, relay, and wiring are all good but the pump does not run, the fuel pump itself is likely defective.

Replacement Options and Costs

When it comes to replacing the fuel pump on your 2013 F-150, you have several options:

OEM Ford Fuel Pump

The genuine Ford fuel pump assembly, part number BL3Z-9350-A or BL3Z-9350-D, is available from Ford dealers and online parts retailers. The cost ranges from about $157 to $300, depending on the specific part number and whether you need the full sender and pump assembly. OEM parts guarantee perfect fit and performance matching the original specifications, but they come at a premium price.

Aftermarket Fuel Pumps

Several aftermarket manufacturers offer fuel pumps for the 2013 F-150. Quality and performance vary greatly, so it is important to choose a reputable brand. Brands like Bosch, Walbro, Delphi, and ACDelco have established reputations for reliability. Aftermarket pumps can be significantly cheaper than OEM, but you must ensure compatibility with your specific engine and fuel system.

Performance Fuel Pumps

If you have modified your engine for increased horsepower, a performance fuel pump may be necessary. Brands like Walbro and KEMSO offer high-flow pumps that can support up to 600 horsepower or more. These pumps are designed for both naturally aspirated and forced induction applications.

Total Replacement Cost

The cost of the fuel pump itself ranges from $200 to $600, depending on the brand and type. Labor costs add another $200 to $500, depending on the shop's labor rate and the complexity of the job. The total replacement cost typically falls between $400 and $1,100. Factors affecting labor time include ease of access to the fuel tank and the presence of rust or corrosion.

Fuel Pump Removal and Installation

Replacing the fuel pump on a 2013 F-150 is a job that many DIYers can handle, but it requires careful preparation. Here is a simplified overview of the process:

  1. Relieve fuel system pressure: Locate the fuel pressure relief valve on the fuel rail and depress it to release pressure. Gasoline is extremely flammable, so take all necessary precautions.
  2. Disconnect the battery: Always disconnect the negative battery terminal before working on the fuel system.
  3. Remove the fuel tank: Either drop the fuel tank or remove the truck bed. Most home mechanics find it easier to remove the bed.
  4. Remove the fuel pump module: Use a large pair of pliers or a brass punch to turn the retaining ring counterclockwise until it is loose. Lift the module out of the tank, being careful not to damage the float arm.
  5. Replace the O-ring: Discard the old O-ring and install a new one. Apply a thin coat of heavy grease to hold it in place during assembly.
  6. Install the new pump module: Align the marks on the module and tank before tightening the retaining ring. Connect the vent line quick-connect fitting.
  7. Test for leaks: After installation, turn the ignition on and check for leaks before starting the engine.
