* Labor costs: This varies widely by location (rural vs. urban, etc.) and the shop's hourly rate. Expect to pay anywhere from $50 to $200+ in labor. DIY is significantly cheaper, but requires mechanical aptitude.
* Part cost: The fuel pump itself can range from $100 to $300+ depending on the brand (OEM vs. aftermarket) and where you buy it (dealer vs. auto parts store online vs. local store).
* Additional parts: You might need new fuel filter, fuel pump gasket(s), or other related parts, adding another $20-$50 to the cost.
* Difficulty of access: The G20's fuel pump location could make the job easier or harder, impacting labor time.
Therefore, a reasonable estimate for the total cost would be between $250 and $600 or more. Getting multiple quotes from different mechanics is highly recommended. If you're mechanically inclined, doing it yourself could save you considerably on labor costs, but remember to prioritize safety and follow proper procedures.
