To find the correct fuse, you'll need to consult your Jeep Wrangler's owner's manual. It will have a fuse box diagram showing which fuse(s) are related to the fuel pump circuit or the fuel pump relay. The relay itself is also a crucial component for the fuel pump's operation; a faulty relay can also cause the pump to not function.
Without knowing the specific year and model of your Jeep Wrangler, it's impossible to give a more precise answer. Always refer to your owner's manual for the most accurate information.
