The setup consists of a cheap 3-gallon coolant pump, some 3/8" vinyl

about 15" long. *Only one needle valve and tube is in current use.

You can do this without the pump if you hang the coolant tank (coffee
can, maybe) from the ceiling and let it gravity feed.

Yep. The coolant pump zero-flow pressure is a few psi, maybe 5 psi, so
a tank hanging from the ceiling will generate adequate pressure. But a
coffee can may not be big enough.

For the record, the 1 gallon Little Giant VMC-1 coolant pump has a 11.5
foot head at zero flow.
