If they did, I would probably know by now. I say that only because our prototype tester is a part of a Nissan dealership, and he would have most likely noticed a change in the part number. If the tank itself using the same part number has been revised, then we will know that shortly when his new tank arrives.
BTW Our prototype is in the Performance Motorsports 370z. I dont think they post a whole lot, but I did a quick search and found they have some videos on youtube but they dont add any descriptions or anything. I havent been there in person to see anything, but I assume this is the car running the prototype:

I cant recall when he installed the prototype, I would have to look back thru this thread at my old posts... I dont think it was in the car in that video.
