Can you access the fuel pump on a 1999 Oldsmobile bravada without dropping tank?

No, you generally cannot access the fuel pump on a 1999 Oldsmobile Bravada without dropping the fuel tank. The fuel pump is located inside the tank itself, and there's no other way to reach it on this model. While some vehicles have access panels, the Bravada's design doesn't include one for the fuel pump.
