MAC valve used for Dejon Tool 1g BOV mod

[gprix1]

Well I'm a fan of the Dejon Tool 1g BOV stop leak mod' and today I went to buy one and could not find it on the site. I gave him a call and he said they just weren't selling enough of them so they no longer stock them.
He said it was a MAC series 100, pilot operated valve that could be purchased from an industrial suppy store but when I look it up there are several variations of this valve and I'm not sure which one to get. Would anyone happen to know the correct part number for this?

Call them back up and ask, I'm sure they would know.

I don't think he felt like looking it up and I just left it at that figuring I would find it easy enough from what he did say. If nobody knows what the part number is I'll call back or email him if necessary and hopefully get an answer.
