I used Dwn4nythng idea when I tried to make my own air hose. It works perfect. The only thing, I put a little silicone on the inside of the metal inlet (the side that touches hose inside) to to glue it to the silicone hose and let it dry. All you need is :
- 3/8 BRB x 3/8 MPT Barb-MPT Adapter (@ Osh)
- Pin Clip .062" Dia. x1" L (@ Osh)
here is a video he posted. It gives more clear pic how to do it.

It worked really good for me and it was tight. I didnt have any problem with idle. I would recommend to choose drill bit with the right diameter. I tried a few bits on a separate piece of hose and picked the one that was the best. Hope it makes sence. I have my hose still laying in a garage, I can make pics if it wasnt too clear. Once again, its Dwn4nythng idea, not mine and i think it will work perfect for what you are looking for.
