I don't know exactly how old my DualV is, but it's definitely over 10 years old (I inherited it about 8 years ago). When the plastic around the water tank valve started to crack I was very upset but luckily this tank fits perfectly! As others have said you need a grip off your old tank and it snaps right into place. The tank is actually even a bit more bitter than my old one, which is nice. There are no logos on it, but I didn't worry about that while it was working. I'm just glad I only had to spend $35 on it instead of buying a brand new car!
