I ordered a pulse-g clone from slowtech, and when it came in the glass tank was broke into pieces. Instead of trying to get them to send me another tank I decided to just order some replacements since they are so cheap. Well, once they came in I thought "hmmm, this looks a lot like the glass on my hybrid. Well, sure enough it fits! It is actually a bit shorter than the original, but it makes the top cap stay on better since it has more surface area exposed on the top o rings. No leaks, easy on and off. So if you have the hybrid mod go ahead and give these replacemnt tanks a try.
