@erics - that I did not do - the huma plenum tube didn't have a hole in it so I didn't add one. The huma reg itself ( if memory serves - and thats questionable . . . lol ) does have a tiny little hole in it that I'm assuming is for venting. Something else you may want to do that I learned from when I put a huma in my marauder - file the threads on the little screw that goes into the reg at the intake side of it ( where you make adjustments ). See page 5 of this document.
