Its very easy to replace the fuel pump. I did it in about 30 minutes with very little mechanical knowledge or skill.

There is an access underneath the rear seat.
-remove a circular plastic cover (about 8 inches diameter)
-disconnect wire harnesses
-there is a ring clamp that goes around the unit, loosen it and remove it
-pull of the black plastic ring that runs around the outside of the fuel pump
-pull the fuel pump straight out.
-Put the new one in and go through the steps in reverse
