can someone help by naming the parts to buy so i can go pick them up and take care of this OSCAI. thanks

 

Pretty much everyone is using slightly different parts. Basically select your hose size... 3" should be exactly the same size as the hole (it's the same size I used). Try to get a material you can cut easily. Then get a coupler that will join 3" to whatever hose size you choose (3"-3" in my case). It's a DIY deal so there's no set parts to buy.

 

As punkdork said, everybody has got their own version. Here's mine:
