Hello Taylor
How are you doing? In replacing the fuel pump, be sure that the car is shut off. You can remove the cable going to the battery underneath the seat behind the passenger side. I strongly suggest that you take a picture of every connectors of the battery and it's best to put a tag on each cable so that you will have a guide in reinstalling everything.
About the fuel pump, you can access the fuel tank underneath by removing the metal band with two bolts holding it. You may need to remove some fuel if it's full. I will send you some videos that you can use as guide.

Just remove the battery connector first before doing anything. Below is a picture where you should disconnect it. Then put tags on everything you will remove then take a picture so that you won't be lost.
Hope this helps and hope to get your vehicle back to it's normal operating state. Have a good one!
Thank you
Relly
