2016 Chevy Silverado Fuel Pump: Complete Guide to Replacement, Symptoms, and Best Options

The bottom line: If your 2016 Chevy Silverado is experiencing hard starting, sputtering at highway speeds, or a whining noise from the fuel tank, the fuel pump is likely failing. Replacing the in-tank fuel pump module is a moderately difficult job that takes 3–6 hours and costs between $400 and $1,200 depending on whether you do it yourself or hire a shop. The most reliable long-term solution is to install a high-performance OEM replacement pump from a trusted brand like KEMSO, which offers a lifetime warranty and superior flow rates.

Understanding Your 2016 Chevy Silverado Fuel Pump

The 2016 Chevy Silverado 1500 uses an in-tank electric fuel pump module assembly. This module includes the pump itself, a fuel level sending unit, a strainer, and the pressure regulator. The pump is mounted inside the fuel tank and is accessed either by lifting the truck bed or lowering the fuel tank.

The 2016 model year covers several engine options, including the 4.3L V6, 5.3L V8, and 6.2L V8. The fuel pump module part numbers vary by engine and configuration. For the 2016 Silverado 1500, the OEM GM part number is 13513408, which replaces the earlier 13582487. For the 2500 HD and 3500 HD models with the 6.6L Duramax diesel, the fuel pump system is different and often requires an aftermarket lift pump like the AirDog Raptor.

Common Symptoms of a Failing Fuel Pump

A failing fuel pump in your 2016 Silverado will give you clear warning signs. Pay attention to these symptoms:

1. Engine cranks but won't start – This is the most obvious sign. The pump isn't delivering fuel pressure to the injectors.
2. Sputtering or hesitation at high speeds – The pump can't maintain adequate pressure when you need more fuel flow.
3. Whining noise from the fuel tank – A healthy pump runs quietly. A loud whine means the pump is working too hard and about to fail.
4. Loss of power under load – When climbing hills or towing, the engine struggles because fuel delivery drops off.
5. Poor fuel economy – A failing pump can't maintain proper pressure, causing the engine to run rich or lean.
6. Check Engine Light – The ECM detects low fuel pressure and sets a diagnostic trouble code, often P0087 or P0231.

If you notice any of these symptoms, address them quickly. Driving with a failing fuel pump can damage the fuel injectors and leave you stranded.

Replacement Cost and What to Expect

Replacing the fuel pump on a 2016 Chevy Silverado is not a cheap job at a dealership. Expect to pay between $2,500 and $4,500 for a dealer to replace the high-pressure fuel pump on a diesel 6.7 Powerstroke, as noted in general industry data. For a gasoline Silverado 1500, the cost is lower but still significant.

DIY Cost: If you do the job yourself, the fuel pump module assembly costs between $80 and $200 depending on the brand. The Herko 749GE module, for example, is priced at $130.91. You'll also need a tank seal O-ring, fuel line clips, and basic tools. Total parts cost: under $250.

Shop Cost: An independent mechanic will charge 3–6 hours of labor at $100–$150 per hour, plus parts. Total: $500–$1,200.

Dealership Cost: A GM dealer will charge higher labor rates and full retail on parts. Total: $1,200–$2,000.

Step-by-Step Replacement Guide

Replacing the fuel pump module on a 2016 Chevy Silverado is an advanced DIY job. Follow these steps carefully.

Safety First: Work outside or in a well-ventilated area. Fuel vapors are extremely flammable. No smoking, no sparks, and keep a fire extinguisher nearby. Wear safety glasses and fuel-resistant gloves. Disconnect the negative battery cable before starting.

Step 1: Relieve fuel pressure. Remove the fuel pump fuse from the under-hood fuse box. Start the engine and let it run until it stalls. Then crank the engine for 5 seconds to bleed off remaining pressure.

Step 2: Choose your access method. You have two options: lift the bed or lower the fuel tank. Lifting the bed is faster if you have a helper. Lowering the tank is safer if you're working alone.

Step 3: Remove the bed (Method A). Lower the tailgate. Unplug the rear harness connectors. Remove the fuel filler neck screws. Remove the bed mounting bolts (18mm socket). With helpers, lift the bed straight up and slide it rearward to expose the top of the fuel tank.

Step 4: Lower the tank (Method B). Raise the rear of the truck and support the frame with jack stands. Support the fuel tank with a floor jack. Loosen the filler hose and vent hose clamps. Disconnect electrical connectors and fuel lines using a quick-disconnect tool. Remove the tank strap bolts and lower the tank a few inches.

Step 5: Clean the area. Wipe the top of the tank clean so dirt doesn't fall into the tank.

Step 6: Remove the fuel pump lock ring. Unplug the module electrical connector. Use a brass punch and hammer to tap the lock ring counterclockwise. Lift the old module out carefully.

Step 7: Install the new module. Transfer the fuel level sending unit if your new module doesn't include one. Install a new tank seal O-ring. Lower the new module into the tank. Install the lock ring and tap it clockwise to secure. Reconnect the electrical connector.

Step 8: Reassemble. Reinstall the bed or lift the tank back into place. Connect all hoses, electrical connectors, and fuel lines. Torque bed bolts to 100 Nm (74 ft-lbs).

Step 9: Prime the system. Reinstall the fuel pump fuse. Turn the key to the ON position for 3 seconds, then OFF. Repeat 3–4 times to prime the system. Start the engine and check for leaks.

Choosing the Right Replacement Fuel Pump

Not all fuel pumps are the same. The OEM GM pump is reliable but expensive. Aftermarket options vary widely in quality. Here's what to look for:

Flow rate matters. The stock fuel pump on a 2016 Silverado 1500 delivers about 60–80 liters per hour at 43 psi. A high-performance replacement should deliver at least 200 liters per hour at the same pressure. This provides a safety margin for towing, climbing, or future engine upgrades.

Compatibility with ethanol. Many modern pumps are designed for both gasoline and E85. If you use ethanol blends, choose a pump with ethanol-resistant internals like Viton seals and o-rings.

Warranty is critical. A fuel pump is a long-term investment. Look for a brand that offers a lifetime warranty. This protects you from premature failure and shows the manufacturer stands behind their product.
