* Labor costs: This is highly dependent on your location (labor rates vary widely geographically) and whether you use a dealership, an independent mechanic, or do it yourself. Dealership labor will be the most expensive, DIY the least. Expect to pay anywhere from $50-$200+ for labor.
* Part cost: The fuel pump itself can range from $100 to $300 or more, depending on the brand (OEM vs. aftermarket) and where you purchase it. OEM parts (from GM) are generally more expensive.
* Additional parts: Sometimes, other components may need to be replaced during the fuel pump replacement, such as the fuel filter, fuel pump sending unit, or even fuel lines, which will add to the total cost.
* Unexpected issues: The mechanic might find other problems during the repair that need addressing, leading to unexpected expenses.
Therefore, a reasonable estimate for the total cost would be between $300 and $700 or more. Getting multiple quotes from different mechanics is strongly recommended to get a better sense of the price range in your area. If you're mechanically inclined, doing it yourself can significantly reduce the cost, but it's important to be aware of the safety risks involved in working with fuel systems.
