NB fuel tank - tipover valve inside?

Building a car for time attack and getting rid of all the emissions control devices. Running some new line for fuel tank ventilation and i don't see a tipover valve mounted on the tank like the NA seems to have.  Does anyone know if there is an internal tipover valve inside the tank of NB's (NB2 specifically)?  

I replaced mine in my 1999, I can't imagine there would not be one in a NB2. It was a small cap like structure away from the main fuel lines, to the passenger side on top of the tank. Difficult to see if I recall correctly with the tank in the car. I replaced my tank and it was easy to see in that instance. I would keep looking if the tank is in the car, I just don't think you have found it yet. Or go on the mazdamotorsports site, pull up the schematic for the Emissions/fuel

Good luck
