Can this replace a K4645 Tank

The one I have has flushmate pressurized unit within it. It was a unit that is on recall and could decide to replace the parts sent to me, but I read there is some risk of tank exploding, so rather not risk it. The bowl connected to though say 1.4 GPS or less - it is back outlet vs floor outlet. I would like to keep the bowl intact and only change the tank as would be a bit of a pain to change out the bowl. Also, if not this tank, then which one would work? Thank you in advance.
Asked by: Burton
Hello, my name is Andrea with Kohler Customer Service. I am happy to assist you with your toilet question. I am sorry to advise the only tank which will work with your rear flush bowl is model number 4645. If you have concerns about replacing your parts in the flush mate tank, Sloan Flush mate would be more than happy to address those concerns. However if you decide to replace the toilet please work with your local Home Depot to help identify an alternative toilet for your requirements. Thank you for choosing the Bold Look of KOHLER.
