I just ordered a bunch of o-rings from McMaster-Carr for my KFL, and other stuff. http://www.mcmaster.com/#catalog/120/3508/=rpyleq
The o-rings are spec'd by ID & thickness. All dimensions below are mm. Sold in packs of 100. But really inexpensive. They ship fast.
Fill screw: 2 x 1
Chimney: 5 x 1.5
Base, sections: 18 x 1
Quoting this for future reference, thank you for the info!
