Autozone.com has repair guides. They only have guides up through the '95 or '96 year model, but it should be very close to what you have.

On the '96 and later year models the fuel pump is held in place with a large snap ring. If you don't have snap ring pliers, you'll need some.
Don't forget to relieve the fuel pressure on the fuel system first.
