Are you guys talking about TIG coolant? I am not familiar with a "sump".

No, cutting fluid for the milling machine. It is a "milk" made of
water and concentrate that prevents rust, cools cutting bits,
lubricates the point of cutting. The "sump" is a tub in the bottom
of the mill where the fluid collects. It also is a point where tramp
way oil collects, which causes problems with lack of oxygen and
anaerobic bacteria.

I wasn't getting it, but understand now. I'd add a little green food
coloring, and market it as Mean Green, the Planet Friendly Coolant. You can
use the name, just remember me every Christmas with a card and some "real"
green.
