The o-ring on the base on some of these Dvarws is too thick. Use one of the thinner o-rings from the spares bag and the tank will screw off easily without having to take it off the mod.

Did u experience this with the FL version as well?
I have 22 and 24 FL and non FL
Glass tank is nice and coil maybe placed easier
but i doubt that it was a FL
I want non FL with Pyrex tank and clamps, old threads and chimney cap were much easier to handle.
