Ideally, the tubing should be PTFE. Teflon is slippery and will have much lower friction with the filament. I use 4mm ID, 6mm OD style. I did not get the 4mm OD, 2mm ID stuff, seemed to me it would just be more likely to bind with the filament.

If you have a setup that can support the single long hoses, that should work fine.
