The fuel pump on a 1994 Cadillac DeVille is mounted in the gas tank. This pump is responsible for getting gasoline from the tank to the engine. Should the pump fail or start to fail, then the engine will first have trouble running before failing completely in turn. Replacing the fuel pump takes at least an hour, but does not require any special tools or equipment.
