The fuel pump replacement part for a 2004 Chevy Silverado typically costs between about $60 and $600, depending on whether you choose a remanufactured, aftermarket, or OEM unit, with labor and other fees added on top.
In 2004, the Silverado generally uses an in-tank electric fuel pump located inside the fuel tank. Replacing it usually involves draining the tank and removing the pump assembly, and prices can vary by engine type (4.3L V6 or 5.3L V8), supplier, and warranty options.
What affects the price
Several factors drive the total cost of a fuel pump for a 2004 Silverado, including the pump type, brand, warranty, and where you buy it. Understanding these can help you compare prices and choose the right option.
Remanufactured vs. new
Remanufactured in-tank fuel pump modules are typically the least expensive option, often selling in the $60–$150 range. New aftermarket assemblies usually run higher, roughly $120–$250. OEM dealership parts can push the price upward to the $350–$600 range or more.
Brand and warranty
GM/OEM-grade parts often cost more but come with longer warranties and guaranteed compatibility. Aftermarket brands (such as ACDelco, Spectra Premium, Delphi, or Duralast) offer lower prices but vary in warranty terms and longevity. Warranties differ by seller and part type, so read the fine print carefully.
Parts options and price ranges
Prices vary by source and specification; here is a quick breakdown by type.
- Remanufactured in-tank fuel pump module: typically $60–$150
- New aftermarket in-tank fuel pump assembly: typically $120–$250
- New OEM/GM dealership fuel pump assembly: typically $350–$600
- Fuel pump kit with sending unit (aftermarket): typically $100–$200
Prices can fluctuate based on availability, shipping, and special promotions. Always verify compatibility with your specific engine (4.3L V6 or 5.3L V8) and model year, and check whether the price includes the sending unit and gasket kit.
Where to buy and how to compare prices
Smart shopping can save you hundreds of dollars. Consider multiple sources and compare prices, warranties, and return policies before purchasing.
- Major auto parts chains (AutoZone, Advance Auto Parts, O'Reilly): typically stock aftermarket in-tank assemblies in the $120–$250 range; OEM options are usually higher.
- Online retailers and marketplaces (RockAuto, Amazon, PartsGeek): often have broader brand choices and may show remanufactured options in the $60–$150 range plus shipping.
- GM dealership or authorized dealers: generally the most expensive, often $350–$600 or more for a new OEM unit.
When comparing prices, also consider whether the price includes the sending unit, harness, and fuel tank seal, as these add-ons can push the total cost. Check customer reviews for reliability and confirm compatibility with your truck’s engine code (e.g., 4.3L or 5.3L).
Labor and total cost expectations
Labor costs depend on local rates and how the work is performed (garage vs. DIY). Replacing an in-tank fuel pump typically requires removing the fuel tank, which is a moderate to extensive job.
- Estimated labor time: 2–4 hours, depending on access and technician experience
- Common labor rate range: $80–$150 per hour (varies by region and shop)
- Estimated installed price range (pump part + labor): roughly $260–$1,000+
DIYers with appropriate tools may save on labor, but tank removal and fuel system work carry safety risks and require proper precautions. Professional installation often ensures warranty coverage and proper resealing of the fuel system.
Summary
For a 2004 Chevy Silverado, plan for a fuel pump part price that ranges from about $60 to $600, depending on whether you choose a remanufactured, aftermarket, or OEM unit. Labor and additional components can push the total installed cost higher, typically in the $260–$1,000+ range. Compare multiple retailers, pay attention to warranties, and confirm compatibility with your engine variant to avoid surprises.
