Can you change the fuel pump on a 1991 305 Chevy Camaro without dropping tank?

No, you generally cannot change the fuel pump on a 1991 305 Chevy Camaro without dropping the fuel tank. The fuel pump is located inside the fuel tank on this model. While there are some vehicles where access is possible from above, the Camaro's design requires tank removal for proper access and safe fuel pump replacement. Attempting to do it otherwise is risky and could lead to damage or injury.
