Don't bother replacing it. Remove the useless piece of junk (2 screws hold it to the firewall), and cut, and cap the "vacuum" line that feeds it. IT WILL NOT AFFECT YOU'RE EMISSIONS! I have the same jeep as you bro, and I did this a year ago with ABSOLUTELY NO PROBLEMS... My email is firstname.lastname@example.org. Im NO MECHANIC, but I KNOW THIS JEEP.. lol.. F******g YJ's... good luck..
