Kohler Toilet Tanks
Kohler toilet tanks are often marked with the part number stamped with ink or directly embossed into the tank. Their part numbers typically start with a K followed by 4 numbers, such as K4620 or K4519. The K is not always present, and often Kohler adheres a rectangular sticker inside their tank covering up the part number. The sticker will have its own part number listed on it, but that is the part number of the sticker, not the tank, and the sticker is often used on many of their products. If you cannot locate the part number stamped in the tank, remove the sticker to see if you can reveal it behind it.
