To find the correct fuse and relay, you need to consult your owner's manual. The manual will show you the fuse box diagrams and identify the fuse that provides power to the fuel pump relay. The relay itself will likely be in the same fuse box. It's usually a larger component than the fuses.
Without the owner's manual, it's difficult to give precise locations. The fuse box is typically located under the hood or under the dashboard.
