On a 2001 Pontiac Grand Am, you typically
do not have to drop the fuel tank to change the fuel pump. Access is usually possible by dropping the fuel tank access panel (located under the rear seat in most cases) and working from there. However, some mechanics might choose to drop the tank for easier access depending on their comfort level and the specific condition of the vehicle.
Before attempting this repair, consult a repair manual specific to your 2001 Grand Am. The manual will provide detailed instructions and will help you determine if dropping the tank is truly necessary in your situation. Improperly working on the fuel system can be dangerous due to the flammable nature of gasoline.
