Forgive me for being so persnickety, but
I don't think the item in the link is the one you want unless you already own a vacuum gauge that you plan to use in conjunction with the Mityvac. I think (please correct me if I'm wrong) that you want a model that includes a gauge and a bunch of other adapters, not just the brake bleeding stuff. At the same site, it's
this one (plastic) or
this one (metal) . I think shipping is free on orders of $50 or more from them.
