What I did not know / understand initially is that G1/4 thread is NOT 1/4 pipe thread. So the local hardware store is not going to have any (barb-) fitting for you. Hesitating at first, I finally ended up buying (expensive) Enzotech elbows to connect from G1/4 to 1/4 ID soft tubing. SImilar to these:
Coolant seems to vary with the phase of the moon on the day the machine was put together. I've seen Red, Pink, "Diesel Fuel" Color...mine's Blue.
What is it that they are putting in there?
My machine arrived with the reservoir a hair under 1/3 "full"...presumably because they swapped out the pump before they sent it on from Ohio and didn't top it off. Good to see that the flow indicator that Minn posted has a choice of at least two different "wheel colors"

The factory uses a Blue variety of the recommended Propylene Glycol antifreeze...however, here in the US all similar antifreeze products vary in color by manufacturer. Typically a shade of Red to pink.
As long as it's an RV/Marine grade propylene glycol it would be correct.
Automotive ethylene glycol is harmful to the seals in the pumps and can cause a failure very quickly.
