That depends on whether your engine has a carburettor or is fuel injected. If your engine has a carburettor the fuel pump is on the lower engine block. If your engine is fuel injected the fuel pump is in the gas tank. Tell me which engine you have and I can give a more specific answer.
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.

All 1988 Chevy Celebritys are fuel injected. As information 1986 was the last year of carburated engines, it was the 2.8L V6.
If your car has the fuel injected V6 the fuel filter is next to the fuel tank. If your car has the carburetor the fuel filter is in the inlet to the carburetor.
If your engine has a carburetor the filter is in the supply line into the carburetor. If your engine is fuel injected the filter is right next to the gas tank in the fuel line.
