Refilling Voss, prime needed?

[Pvtgloss]

I think I know the answer but figured I'd ask. I have a diy Voss container hooked up to DOS with black rodi tubing. So I can't see if there is air in line. When I unhook the bulkhead from the tube and unscrew the bottle open is it necessary to prime the dosing tube every time? I have been doing it just to be safe.

It's a lot easier to tell if you run the clear tubing, that's for certain. I think priming it for a few seconds every time you switch it out is probably a good idea.
