2013 Chevy Silverado Fuel Pump: Complete Guide to Symptoms, Replacement, and Best Upgrade Options

The bottom line: If your 2013 Chevy Silverado 1500 is experiencing hard starts, sputtering during acceleration, loss of power, or a whining noise from the fuel tank area, your fuel pump is likely failing. The factory pump typically lasts 100,000 to 150,000 miles, and when it goes, replacing it with a high-performance aftermarket unit like a KEMSO fuel pump not only restores your truck's performance but also delivers more flow, better reliability, and a lifetime warranty. This guide covers everything you need to know about diagnosing, replacing, and upgrading your 2013 Silverado fuel pump.

Common Symptoms of a Failing Fuel Pump in the 2013 Silverado

The fuel pump in your 2013 Chevy Silverado is an electric motor that sits inside the fuel tank. It pressurizes fuel and sends it to the injectors. When it starts to wear out, you will notice one or more of these symptoms :

1. Hard Starting or No Start
Your truck cranks but takes longer than usual to fire up. In severe cases, the engine cranks but never starts. This happens because the pump cannot build enough pressure to push fuel to the injectors.

2. Engine Sputtering During Acceleration
You step on the gas, and the engine hesitates or stumbles. This is a classic sign of fuel starvation. The pump cannot keep up with the demand for fuel when you need power.

3. Loss of Power at Highway Speeds
Your Silverado struggles to maintain speed on the highway. You may feel a lack of power when going uphill or trying to pass another vehicle. The engine simply isn't getting enough fuel.

4. Whining or Humming Noise from the Fuel Tank
A healthy fuel pump makes a quiet hum. If you hear a loud whining or buzzing sound coming from the rear of the truck near the fuel tank, the pump is working too hard and is close to failure.

5. Engine Stalling
The truck may stall unexpectedly, especially when the fuel level is low. This is a dangerous symptom and indicates the pump is on its last legs.

Diagnosing the Problem Before You Replace

Before you drop the tank and replace the pump, rule out these other common fuel system issues that mimic pump failure :

Check the Fuel Pump Relay
The relay is located in the power distribution center under the hood. If the relay fails, the pump gets no power. Swap it with a known good relay of the same type to test it. This is a cheap and easy fix.

Check the Fuel Filter
A clogged fuel filter can cause the same symptoms as a weak pump. The filter should be replaced every 30,000 to 50,000 miles. If you haven't changed it recently, start there.

Test Fuel Pressure
The only way to be sure the pump is bad is to test fuel pressure with a gauge. For the 2013 Silverado, the fuel pressure should be around 55 to 62 psi at idle. If it is lower than spec, the pump is likely failing.

Replacement Guide for the 2013 Chevy Silverado Fuel Pump

Replacing the fuel pump on a 2013 Silverado involves dropping the fuel tank. This is a moderate DIY job that takes 3 to 5 hours. Here is the step-by-step process :

What You Will Need:

  • New fuel pump assembly (KEMSO recommended)
  • Socket set and ratchet (metric and standard)
  • Flathead and Phillips screwdrivers
  • Fuel line disconnect tools
  • Jack and jack stands
  • Safety glasses and gloves
  • Fire extinguisher (safety first)

Step 1: Relieve Fuel System Pressure
Start with as little fuel in the tank as possible. Remove the fuel pump fuse from the fuse box. Start the engine and let it run until it stalls. Crank the engine a few more times to clear remaining fuel from the lines. Disconnect the negative battery cable.

Step 2: Release the Fuel Tank Straps
Jack up the rear of the truck and support it on jack stands. Place a floor jack under the fuel tank for support. Remove the fuel tank straps. There are two straps that hold the tank in place.

Step 3: Lower the Tank
Carefully lower the tank a few inches so you can access the top of the fuel pump module. Disconnect the fuel lines using the disconnect tool. Disconnect the electrical connector. Fully lower the tank and set it on a work surface.

Step 4: Remove the Old Pump Assembly
Clean all dirt and debris from the top of the tank. Use a hammer and drift or a lock ring removal tool to loosen the locking ring. Turn the ring counterclockwise until it comes off. Lift the old pump assembly straight out of the tank. Be careful—the tank will still contain some fuel.

Step 5: Install the New KEMSO Pump Assembly
Transfer the rubber seal (O-ring) from the old module to the new one, or use the new one included in the KEMSO kit. Insert the new pump assembly into the tank, making sure the float arm is oriented correctly. Hand-tighten the locking ring, then tap it snug with a hammer and drift. Reconnect the fuel lines and electrical connector.

Step 6: Reinstall the Tank
Lift the tank back into position. Reinstall the fuel tank straps and tighten them. Reconnect the battery and install the fuel pump fuse.

Step 7: Prime the System
Turn the ignition key to the ON position for 10 seconds, then turn it off. Repeat this cycle 3 to 4 times to prime the fuel system and fill the new pump with fuel. Check for leaks at the connections.

Step 8: Start the Engine
Start the engine. It may run rough for a few seconds as air is purged from the fuel lines. Let the engine idle and check for leaks again. Take the truck for a test drive to confirm the repair is complete.

How to Make Your New Fuel Pump Last Longer

Once you replace your fuel pump, follow these simple rules to extend its life :

  1. Keep Your Tank Above a Quarter Full
    This is the single most important thing you can do. The fuel pump is cooled and lubricated by the fuel it sits in. Running the tank low causes the pump to run hot, which shortens its life. Make it a habit to refill when the gauge hits a quarter tank.

  2. Replace the Fuel Filter
    A clogged fuel filter puts extra strain on the pump. Replace the filter every 30,000 to 50,000 miles to keep the system running smoothly.

  3. Use Quality Fuel
    Low-quality fuel can contain contaminants that wear out the pump faster. Stick to top-tier gasoline from reputable stations.

  4. Avoid Running the Tank Dry
    If you run out of gas, the pump will suck air and run dry. This can damage the pump instantly. Never let the tank go below empty.
