Putting an older tank on a '99. What about emmissions stuff?

OK, So after all my misadventures with body work I'm looking to just replace my tank. I have a 1999. My tank has two small hose attachments coming from the rear of the tank where the seat goes. Any tank older than '99 either has only one or doesn't have them at all. I looked at the pdf repair manual and on pg 44 (of the pdf, not the manual) it has a picture of the whole emmissions system.

Question is: What do I block or remove to put an older tank on my bike? Is it just trial and error; run it and start pulling hoses and see what happens?

Does any of this make any sense????

Here's a pic of my tank.

What you have if you have 2 tubes coming out of the rear is a U.S. California bike, they can be sold anywhere but not the other way around... I bought my 06 here in Tenn. and it was a Cal. bike...... It would give me greif most times after a short stop by starting off good then as you pulled out in traffic or whatever it would start stumbling...... I raised a fuss with a Kaw. rep but to no avail...... I did remove the one tube (right side) and block the tank outlet and left the other (left side tank vent) tube attached & open... +/-3yrs later and still not the first stumble...... Of course it would be illegal to remove it if you are in California...... I would have removed mine even if I had lived in California, as it was an accident looking for a place to happen...... My 03 bought new also, only had the one tube (tank vent) coming out of the tank......
[Edit]--At least that is my take on it, others better qualified may give you more correct answers...

What Old Dog said.

The one on the left is the external vent.

The most important thing to know here is if you buy a older used tank.......Clean it out real freaking well , and check the petcock too.

Nothing worse than slapping on an older tank only to find it has crap in it that ends up clogging up your carbs .................
