Where to route vacuum line on Safari 3.7 tank?

So I removed the flapper valve from the airbox, as I'm sure many do this, and for those who have the Safari tank, where do you route the vacuum hose? It says in the instructions to tee it with the hose that was part of that flapper assembly, but it's gone... What's a good vacuumation area? Thanks.

if you removed the flapper assembly, then you have the hose from the throttle body...reinstall it and run it to your tank...
I removed the flapper also and have the IMS 4.7 tank, I just ran the hose to my tank and had to cap off one of the fittings off my tee...
