How much does it cost to replace a fuel pump on a 2018 Silverado?
Replacing the fuel pump on a 2018 Silverado typically costs between $600 and $1,000 total, with most customers paying about $700 to $900 depending on parts, labor rates, and location.
What to expect when replacing the fuel pump
The fuel pump is located inside the fuel tank for most Silverado configurations. Replacing it generally requires safely draining and removing the tank, installing a new pump module, and testing the fuel system. Symptoms of a failing pump include a no-start condition, stalling, or loss of power under load. The exact process and time can vary slightly by engine option (such as 4.3L V6, 5.3L V8, or 6.2L V8) and by whether the shop uses OEM or aftermarket parts.
Engine options and feasibility
All gasoline engine options for the 2018 Silverado use an in-tank pump module. While the part itself is similar across configurations, labor time can vary based on access and vehicle layout. This is primarily a labor-intensive job due to tank work, rather than a vast difference in part price across engines.
Cost breakdown
The following breakdown offers a general sense of how the total price is assembled. This helps you compare quotes from shops.
- Parts: fuel pump module plus sending unit and related hardware (gasket/seals): typically $120–$350
- Labor: removing the fuel tank, installing the new pump, and testing the system; about 3–5 hours depending on shop and location: $250–$750
- Taxes and miscellaneous fees: $20–$100
The total usually falls in the range of roughly $500 to $1,100, with many customers paying around $700–$900 depending on local labor rates and parts choices. Always request a written estimate that itemizes parts and labor.
Cost by provider and options
Where you get the service can influence price. Dealerships typically charge more, while independent shops may offer lower labor rates. If your vehicle is under warranty or if a recall covers the fuel system, some or all of the cost may be covered.
- Dealerships: often $800–$1,200 total
- Independent shops: typically $600–$1,000 total
- DIY parts purchase (not including labor): $150–$350
DIY can save on parts, but it requires mechanical skill and proper safety precautions. Improper tank work or fuel handling can cause leaks or fire hazards, so assess your comfort level and consider professional installation if in doubt.
Warranty and considerations
Warranty coverage
Fuel pump replacements are not typically covered under standard ownership unless the vehicle is still under factory or powertrain warranty, or if there’s a recall related to the fuel system. Some independent shops may offer labor warranties on the installation, so ask about coverage and duration when you receive a quote.
What to do next
If you’re experiencing symptoms such as a no-start, stalling, or inconsistent fuel pressure, schedule a diagnostic with a trusted shop to confirm whether the fuel pump is failing before proceeding with replacement. Obtain a written estimate that clearly lists parts, labor, and any additional fees, and ask about OEM versus aftermarket parts and the pump’s warranty.
Summary
For a 2018 Silverado, the typical cost to replace the fuel pump ranges from about $600 to $1,000, though many estimates land around $700–$900. Price variability comes from engine type, part choice, and regional labor rates. Always compare multiple quotes and confirm what’s included in the price before authorizing work.
Closing note
Costs can vary by region and vehicle condition. Consulting several shops for tailored quotes based on your Silverado’s configuration will yield the most accurate estimate.
