I'm looking to do my best at a duplicate K&N. I've run across a problem. I was just gonna get some rubber air hosing to use, but I don't know how to replicate this.

(See attachment) Any ideas on how to run something out of hosing to connect with that without breaking any seals/leaving in loose holes in the hose?

 

If you can't see attachment then go to http://ecx.images-amazon.com/images/I/81yeOlCzaXS.pdf and look at instruction picture #27. Thanks for any help.
