manifold??? ...I've only tried using an adjustable wrench and channel locks to get this things off and have had no luck. So I'm wanting to purchase the exact size wrench so I can get this thing off since I've already rounded one of the edges a tiny bit. I was guessing mabye 23mm or 24mm..but not sure. Also, any advice on the best approach to get this thing off would be great too!
