Help finding fitting for OBA to engine intake

[Stinkbug]

I am trying to find a fitting something like the one circled in green in the attached picture. The only ones I have found so far have a small base and I am not able to secure them as well as I would like to the intake tube.

Ideally it would have straight threads for a nut on the backside and a large base to allow me to use some sort of silicon adhesive to seal it tight. Any help in finding such a barb or other solution to connect a 1/2 heater hose to the intake is appreciated.

Grainger or McMaster-Carr perhaps?

Bulkhead barb or intake emissions fittings. Lots of them out there. The problem will be matching up a curved washer to fit the intake hose but doable.

Two thoughts.

Why not a T on the existing breather line? I think my oba instructions said to do that.

Do you have to use the existing filter? Maybe a small filter right on the end of the oba intake line?

That's my photo. That is a plastic nylon hose fitting I picked up at Home Depot or Ace Hardware. I drilled a hole slightly smaller than the fitting and just threaded it onto the intake tube. I meant to change it to something more permanent and secure but it's been on there for 5 years with no issue

Is that going to the compressor infeed? What's the purpose of the line?

Yes. Idea that it is drawing cold air from cowl (in my case anyway)
