If this is the vehicle that I think it is, yes. With the exception of S/T trucks, all fuel injected GM vehicles from that time period required movement of the tank to replace the pump. Luckily, the Century has a relatively easy tank to drop so long as you can disconnect the fuel lines easily. Spray the connection with penetrating oil a day ahead of time. I strongly recommend replacing the fuel filter and any o-rings along with the pump, and if this application uses a pulsator, get a new one of those as well as a leaky pulsator often leads to a misdiagnosis of failed fuel pump.

Hi, the fuel pump is PROBABLY inside the fuel tank. You would need to drop the gas tank, by disconnecting all the lines of course, and unblot the tank "neck" at where you put the gas in, etc... I have a 1995 Buick Century, and I am thinkng your is the same about. When mine was going, the car was stalling out of nowhere, then finally died. Might be a wise investment to replace the entire tank WITH a "new" used tank WITH a new used fuel pump........... goodluck
