As you may surmise, we drop a lot of TJ fuel tanks for various reasons. I bought one of my few HF things purely to do nothing but drop tanks. It works so well, I'm sad I didn't think of it 10 years ago.Yeah, I'm lazy.
Full, empty, stock height, 4-5" of lift, raised tanks, it just doesn't matter and works perfectly for all of them. If you are really lazy, best money you can spend to stay that way.
