The question is if you hook this up using the inlet and outlet wouldn't it be pulling in fresh air thrpugh that filter which would be un-metered?

The answer to your question is yes. If you use a vented catch can such as the Jaz, you must use it as an "output only" catch can by plugging one of the fittings. In addition, you must plug the now-unused fitting on the air intake boot (where the PCV hose used to go).

So you run this set-up? No problems then? What did you use to plug the intake tube hole?

I run this set up without any problems, although I have a VF-Engineering S/C kit, so my intake piping is different than stock.
The VF intake has a male fitting that plugs directly into the 3/4" PCV return hose. To plug the fitting, I clamped a 2" piece of 3/4" hose onto the fitting and plugged the hose with a 1/2" barbed plug (available in the plumbing department of most hardware stores). I don't know whether this will work with the stock intake tube, but hopefully you can adapt the basic concept.
Finally, be aware that using a vented catch can eliminates the "crankcase scavenging" effect of the stock PCV system, and this theoretically robs you of some top-end power. For me, however, the benefit of not having to replace my oil-fouled MAF sensor on a regular basis (a common problem with VF S/C kits) far outweighs any small top-end power loss.
