Smaller ID and I'm going to radius and polish the ends, but it shouldn't matter. Hopefully it doesn't shoot the liquid out too fast.
If it does, plan B is to run a short section of Ti tube bonded into a larger diameter thinner wall carbon tube. It's tempting to go all-out and prep the surface with trivalent chromium etch before bonding with the same aerospace adhesive used to hold F1 cars together. Sometimes you have to work with what you've got!
6mm OD 5mmID 158mm long!
edit: for the original. imagine carbon would be thicker thus larger OD?
