2013 Ford F150 Fuel Pump Replacement: Complete Cost Guide, Symptoms, and DIY Steps

The bottom line: Replacing the fuel pump on a 2013 Ford F-150 typically costs between $500 and $1,200 total, depending on engine type, labor rates, and whether you choose OEM or aftermarket parts. The pump is located inside the fuel tank, which means the tank must be lowered or removed for access, adding to the labor time. This guide covers everything you need to know: symptoms of a failing pump, step-by-step replacement instructions, cost breakdown, and how to choose the right replacement part.

Symptoms of a Failing Fuel Pump in Your 2013 F-150

If your truck is experiencing any of these issues, the fuel pump is likely failing:

  1. Hard starting or no start – The engine cranks but takes a long time to fire up, or it cranks and won't start at all.
  2. Stalling while driving – The engine suddenly dies, especially during acceleration or when climbing hills.
  3. Loss of power under load – You feel a noticeable lack of power when towing or accelerating uphill.
  4. Whining noise from the fuel tank – A loud, high-pitched sound coming from the rear of the truck indicates a failing pump.
  5. Poor fuel economy – A sudden drop in miles per gallon without any change in driving habits can point to a fuel pump issue.

Replacement Cost Breakdown

The total cost of replacing the fuel pump on a 2013 Ford F-150 varies by several factors:

Parts Cost:

  • OEM fuel pump assembly: $300 to $600, depending on the engine (3.7L V6, 5.0L V8, 6.2L V8, or 3.5L EcoBoost V6)
  • Aftermarket fuel pump assembly: $150 to $450, with quality varying widely between brands
  • Additional parts (seals, O-rings, fuel filter): $20 to $80

Labor Cost:

  • Independent shop (non-metropolitan area): $500 to $900 total
  • Independent shop in a city or dealer-like setting: $900 to $1,400 total
  • Dealership or high-cost urban market: $1,000 to $1,600 or more

DIY savings: If you do the job yourself, you can expect to pay $200 to $500 for just the parts, saving $300 to $1,000 in labor.

Tools and Materials You'll Need

Before starting, gather these essential items:

  • Socket set (metric) and wrenches
  • Floor jack and two jack stands
  • Fuel line disconnect tool
  • Fuel tank sending unit wrench (Ford part number 310-123 or equivalent)
  • Screwdriver and slip joint pliers
  • Drain pan (5-gallon capacity minimum)
  • Safety goggles and nitrile gloves
  • New O-ring seal and clean engine oil
  • Fire extinguisher (keep nearby)

Step-by-Step Replacement Guide

Step 1: Relieve Fuel System Pressure

Disconnect the battery ground cable using a wrench. Locate the Schrader valve on the fuel rail and press the valve stem with a rag to release residual pressure. If the engine can still run, start it and let it idle until it stalls, then crank for about five seconds to relieve remaining pressure.

Step 2: Access the Fuel Tank

Jack up the rear of your F-150 and support it securely on two jack stands. Remove the fuel tank shield if equipped, using a ratchet and socket. Support the fuel tank with the floor jack, then disconnect the straps holding the tank to the truck's body using a ratchet, ratchet extension, and socket.

Step 3: Lower the Tank and Disconnect Lines

Lower the fuel tank just enough to gain access to the fuel lines, vapor lines, and fuel pump electrical connector on top of the tank. Press the lock tabs on the quick-connect fittings and carefully pull the lines from their fittings. Unplug the pump-module electrical connector.

Step 4: Remove the Fuel Pump Assembly

Use the fuel tank sending unit wrench to turn the lock ring counterclockwise. Lift the sending unit/pump module off the tank carefully. Discard the old O-ring seal underneath the flange of the module. Inspect the tank for debris or contamination, as this can damage the new pump.

Step 5: Install the New Fuel Pump

Remove the old fuel pump from the module using a screwdriver and slip joint pliers, then install the new pump onto the module. Lubricate the new O-ring seal with clean engine oil and place it on the fuel tank opening. Install the sending unit/pump module in the tank and turn the lock ring clockwise using the sending unit wrench.

Step 6: Reinstall the Tank

Lift the fuel tank just enough to attach the fuel lines and vapor line, and plug the pump module electrical connector. Raise the fuel tank to its mounting position and secure the tank straps using the ratchet, ratchet extension, and socket. Install the fuel tank shield if removed, then lower your F-150. Connect the ground battery cable using the wrench.

Step 7: Build Fuel System Pressure and Test

Plug the electrical connector located on the frame rail underneath the driver's side door, and attach the splash shield. Turn the ignition key to the "On" position for three seconds to let the fuel system build pressure, then turn it to "Off." Repeat this cycle three times to ensure the system has enough pressure. Start the engine and check for fuel leaks. Listen for the fuel pump's priming cycle (a brief hum) and monitor for stable idle and acceleration response.

Maintenance Tips to Extend Fuel Pump Life

To prevent premature fuel pump failure in the future, follow these simple guidelines:

  • Never run your tank below a quarter full – The fuel in the tank acts as a coolant for the pump. Running low consistently can overheat and damage the pump.
  • Use high-quality fuel from reputable sources – Contaminated fuel can clog the pump's filter and damage internal components.
  • Replace the fuel filter regularly – If your 2013 F-150 is equipped with a separate fuel filter, inspect and replace it as recommended by your owner's manual.
  • Consider using a fuel system cleaner periodically – This helps remove deposits that can affect pump performance.

Common Questions About 2013 F-150 Fuel Pump Replacement

Is it safe to drive with a failing fuel pump? No. A failing pump can cause stalling at highway speeds, which creates a serious safety hazard. Replace it as soon as you notice symptoms.

Can I replace just the pump, or do I need the whole assembly? While you can replace just the pump, the entire module (including the fuel level sender and filter) is typically replaced for simplicity and reliability. The labor cost is the same whether you replace the pump alone or the full assembly.

How long does a fuel pump replacement take? For a DIY mechanic, expect 2 to 4 hours depending on experience and model year. Professional shops typically complete the job in 1.5 to 3 hours.

Will a performance fuel pump hurt my stock engine? A performance pump designed for higher flow, like KEMSO's 340LPH models, will not harm a stock engine as long as it maintains proper fuel pressure. However, it's generally unnecessary for a stock engine—a standard OEM replacement pump is sufficient for most drivers.

Final Thoughts

Replacing the fuel pump on your 2013 Ford F-150 is a manageable repair that can save you hundreds of dollars if you do it yourself. The key is to recognize the symptoms early, use quality parts, and follow proper safety procedures. Whether you choose an OEM or aftermarket replacement, investing in a reliable brand like KEMSO ensures your truck stays on the road for years to come.
