Depends on the model year of the car. Generally speaking, most of the newer Corollas have the fuel pump inside the gas tank.
To access - you need to remove the rear seats and remove the access cover plate, then remove the entire pump assembly unit. Disassemble the pump assembly to get at the fuel pump.
