You can't use gingerbread flavored liquid in plastic tanks?

[crashhat69]

why is this? does it crack the tank or something? I thought only cinnamon and citrus cracks plastic tanks?

I haven't heard this. I know there are a LOT of flavors that will crack tanks, but I've used gingerbread liquid from a couple of different vendors in plastic tanks with no problems. Maybe it depends on the vendor formulation? I certainly wouldn't use it in a plastic tank if that vendor says it is a tank-cracker, but otherwise I think you're OK to do so.
