Fx impact external plenum

The photo is from the forum. Is not mine but I made it same. And I am also a little bit confused with OM valve housing for last impact mkii. The VH I bought is a full body only with the small hole for the bar gauge contact.I see in another dealer site a valve house with 3 long openings . When I order it I gave the code from the latest schematic of fx. I am curious with which one is coming the new impact.

Actually that picture is mine :)

Polish the sharp edges real good, if not the valveH might get stuck
