A typical fuel-pump replacement for an INFINITI G37 costs about $600–$1,200, including parts and labor.
Several factors shape the final bill: the quality of parts (OEM Infiniti vs. aftermarket), the car's model year within the G37 range, local labor rates, and whether additional components or services are needed during the repair (such as replacing the sending unit, seals, or related fuel-system work).
Cost breakdown
The following items outline typical price ranges for parts and what they cover. These figures are common benchmarks, but actual prices can vary by region and supplier.
- OEM fuel pump assembly (in-tank) for G37: roughly $350–$600, depending on year and supplier
- Aftermarket fuel pump assembly (in-tank): roughly $150–$350
- Ancillary components that are sometimes replaced with the pump (sending unit, seals, gaskets, clamps): roughly $20–$100
Prices vary by region and shop, and some repairs may involve core charges, freight, or additional parts if ancillary wear is found during service.
Labor and install details
Labor costs are driven by shop rates and the time required to access and replace the pump. The following ranges reflect typical scenarios for a G37.
- Estimated labor time: about 2–4 hours, depending on vehicle access and service bay workflow
- Typical labor rate: $75–$150+ per hour, varying by region and shop
- Estimated total labor cost (excluding parts): roughly $150–$600
Actual labor costs depend on the exact repair setup, regional labor markets, and whether any related issues are discovered during disassembly (for example, fuel-line fittings or wiring problems).
Getting quotes and choosing parts
When shopping for a fuel-pump replacement, request itemized estimates that separate parts, labor, and any diagnostic fees. Ask whether the quote uses OEM Infiniti parts or reputable aftermarket equivalents, and confirm warranty terms on both parts and labor. Some shops may offer a bundled package that includes the pump, sending unit, seals, and a warranty, which can simplify comparison.
What to ask your mechanic
Key questions include: Is the sending unit included or replaced separately? Are there any known issues with the gas tank or lines in your specific G37 year range? What diagnostic steps are included to confirm fuel-delivery problems versus other fuel-system faults? Is there a warranty on the pump and on the labor?
Regional considerations
Prices can differ significantly by region due to labor markets, parts availability, and shop overhead. Urban areas with higher living costs tend to see higher labor rates, while rural areas may be more affordable. Always compare multiple quotes to ensure you’re getting a fair price for your area.
Summary
Replacing the fuel pump on an INFINITI G37 is a mid-range repair that typically costs between $600 and $1,200 in total, with the bulk of the variation coming from parts choice (OEM vs aftermarket) and local labor rates. By understanding the cost components, requesting detailed, itemized quotes, and factoring in regional differences, owners can make informed decisions and avoid surprises at the shop.
