The fuel pump module for a 2004 GMC Envoy typically costs about $70 to $350 for the part, with total project costs usually ranging from $300 to $850 once labor is included, depending on engine type, part source, and regional labor rates.
The exact price depends on several factors: the engine option (4.2L inline-six or 5.3L V8 in some models), whether you buy OEM, aftermarket, remanufactured, or used, your location, and whether you hire a mechanic or do the replacement yourself. The sections below outline typical costs and buying options.
Part price breakdown
Prices you’ll see when shopping for a replacement pump vary by source and configuration. The list below summarizes common options.
- New OEM fuel pump module: typically about $180–$350
- New aftermarket fuel pump module: about $70–$200
- Remanufactured/refurbished pump module: about $60–$150
- Used/salvage pump from a scrap yard or rebuilt unit: about $20–$60
Prices include the pump module itself; some kits include the sending unit, fuel filter, and mounting hardware, which can affect the price. Always verify compatibility with your VIN and engine.
Engine variations that affect pump price
The 2004 GMC Envoy offered at least two major powertrain setups. While the pump function is the same, slight differences in the fuel system hardware can cause small price differences among engines. In practice, most price ranges above cover both configurations, but OEM parts for certain configurations can sit at the higher end of the range.
Labor and total cost
Labor costs for replacing a fuel pump are driven by tank access, vehicle design, and local shop rates. The ranges below reflect typical prices in many areas, though regional differences apply.
- Estimated labor time: 2–4 hours, depending on tank access and whether fuel system pressure needs relief procedures
- Labor rate: roughly $75–$125 per hour in many regions
- Estimated total labor cost: about $150–$500
Doing the job yourself can lower total cost if you have the tools and safety setup to drain the tank, relieve pressure, and handle fuel-system work. However, mistakes can be dangerous and costly; consult a repair manual and follow safety precautions before proceeding.
Where to buy
Shopping options include both brick-and-mortar and online retailers. Each option offers different price advantages and warranties.
- OEM/GM dealership parts: typically the best fit and most reliable warranty, but often the most expensive
- Major auto parts stores (AutoZone, O'Reilly, NAPA): mid-range pricing with warranties and in-store availability
- Online retailers (RockAuto, Amazon, manufacturer websites): frequently the lowest upfront price, but verify compatibility and return policies
- Salvage yards or rebuilt units: cheapest upfront, with higher risk and variable history
Always confirm that the part fits your exact Envoy model year and VIN, and check the return window and warranty terms before purchasing.
Summary
For a 2004 GMC Envoy, expect a fuel pump replacement to cost roughly $70–$350 for the pump itself, with total job costs typically $300–$850 once labor is included. The exact amount hinges on engine configuration, part source (OEM vs aftermarket vs remanufactured vs used), regional labor rates, and whether you perform the work yourself. Shop around, verify compatibility, and consider replacing the fuel filter to optimize longevity and performance.
