The location of the fuel pump depends on which engine the car has.
If it is the 2.5L 4 cylinder fuel injected engine the fuel pump is in the fuel tank.
If it is the carburetted 2.8L V6 the fuel pump is on the lower part of the engine block on the radiator side of the engine.
The fuel pump on your 1988 Chevy Celebrity is in the fuel tank.
The fuel pump is in the fuel tank.

Chevy didn't make a 1981 Celebrity
On all models of Chevrolet Celebrity with fuel injection the fuel pump is inside the fuel tank.

you need to drop the gas tank down and remove fuel pump from tank.
The fuel pump location depends on the engine in your car. If it is fuel injected the pump is in the fuel tank. If it is the carburetted V6 the fuel pump is on the bottom of the block on the right side of the engine.
