While some parts may be similar across Buick models and even other GM vehicles from around the same time period, it's not guaranteed that a fuel pump from another vehicle will be a direct bolt-on replacement. You'll need to check the specific part number for your 1997 Park Avenue with the correct engine and compare it to the part numbers of potential replacements. You can find this information on the fuel pump itself (if accessible), your vehicle's owner's manual, or through online auto parts retailers by inputting your vehicle's VIN.
Using an incorrect fuel pump can lead to serious problems, so it's crucial to verify compatibility before installation. A professional mechanic or a reputable auto parts store will be able to help you identify the correct fuel pump for your specific 1997 Buick Park Avenue.
