SUPER EASY!!
Two spring loaded switches right in the middle of each seat between the carpet and the seat. Move them to the side and lift the cushion up, you will feel it release. You can do each side one at a time.
Each seat has a conncector for the seat heaters, there is enough harness that you can tilt the seat back and up a bit. Disconnect them.
There are two hooks, one at each back corner of the seats towards the door frame. You will need to push the seat back and up to unhook them. The seats have a wire that runs across the back that the hooks curl up around. The hooks are opened at the top, so you need to get that wire to the back of the hook and then lift. Again, you can do one side at a time.
The seat weights next to nothing... so you can just lift it out.
If you are replacing the fuel pump make sure to have a fuel pump locking ring removal tool... or a rubber mallet and a big screw driver.
