Makes you want to take a look at the other stuff on ebay.
I just scrolled a few that say pressure and vacuum.
But notice the pictures!
None of the gauges have a positive pressure scale
and I don't seem to see any valving to change functions.
Be careful what you buy!
And I think atpchas has the best price linked already.
I bought mine from them, good folks to work with. They have a fairly good sized line card of tools, with many being available for immediate shipping. They are local for me, so about a 15 minute drive and had it in hand.
I have a set of crankcase tools that Matt Olson's designed tools Iam selling them . I'm asking $200 for the tools and some other specialty tools buyer pay shipping I used these twice and they work as designed
