Tank question

[BK_Malik]

Hey Vets,

I saw a tank somewhere that has a tapped filler hole and I can't remember where. Has anyone seen one of these? Thanks for your help!

MiXologist made a nice list of tanks...I only see 1 that has a hole.

There also is what is called a sub tank at MomandPopsvaporshop.com and its similar and $12.
