Asking because I just got in my BMS BOV adapter kit, but the supplied straight barb is too small to be used with the Mishimoto can.
There are a number of options available from RB, including one that has the 1/8" NPT to 3/8" straight barb (usually installed into the intake manifold, but I didn't want to drill/tap) in lieu of the RB throttle body fitting. I believe Earls, Aeroquip, or Vibrant offer them as well. If you use the BMS BOV adapter, you won't need the RB equivalent.

The straight barb supplied with the BMS adapter (which I did not end up using) is for the BOV, not the external PCV system. I used the RB 1/8" NPT to 3/8" for that.
