How do you install a new fuel pump in a 1989 cabriolet?

There are two fuel pumps on that car. One is located under the car back by the gas cap. The other one is in the tank (sort of). The one in the tank can be located by removing your back seat. There is a fuel port - remove it and you can access the internal fuel pump. We have a Chilton book and it tells you to remove the fuel tank - you don't have to, learn from our mistake. Super easy. Don't forget to change the fuel filter too!
