The fuel lines themselves connect to the fuel pump assembly at the top of the tank. These lines then run from the tank to the engine compartment. Their exact routing may vary slightly depending on the engine and options, but they'll generally follow the frame rails.
In short, there's no easily visible external fuel pump or lines. Accessing them requires dropping the fuel tank, which involves some mechanical skill and safety precautions. A repair manual specific to your 1997 Ford Ranger XLT is highly recommended for detailed instructions and diagrams.
