Issue description:
If you insert Ethylene tank into Gas Generator game just FREEZE to death.

Version (make sure you are on the latest version before reporting):
**Forge: 2784
**Mekanism: Mekanism-1.12.2-9.7.2.373

Doesn't happen to me in my dev environment. Is this in single player or on a server?

and which type of gas tank?

Single player
Ethylene creative tank

Will look into fixing this when I get a chance, but I was able to reproduce. (The key thing about the issue is putting it INSIDE the inventory, rather than putting it in the world next to the generator)
