You should be able to pick up a small brass T from most auto shops, just take the hose in so they can find you the right one, I think the bov hose is 3/16, best to check this though, also if you are worried about chopping your stock bov hose in half, you can just use a new length and keep the stock one.
Yes, always use cable ties on your connections, just as an added measure of safety, would you like me to grab yet another pic of mine ?
Oh, and depending on where you run your hose, you will probably need quite a lot of it, mine runs from the bov line, across the front of the engine bay, along the side of the engine bay, through the front guard, into a small rubber grommet in the drivers side door well, then up to the pillar location.
Nearly all men can stand adversity. But if you want to test a man's character - give him power.
